Abstract
Purpose: Direct-to-consumer advertising by industry has
been criticized for encouraging overuse of unproven therapies,
but advertising by health care providers has not been as carefully
scrutinized. Stereotactic radiation therapy is an emerging tech-
nology that has sparked controversy regarding the marketing
campaigns of some manufacturers. Given that this technology is
also being heavily advertised on the Web sites of health care
providers, the accuracy of providers’ marketing claims should be
rigorously evaluated.
Methods: We reviewed the Web sites of all US hospitals and
private practices that provide stereotactic radiation using two
leading brands of stereotactic radiosurgery technology. Centers
were identified by using data from the manufacturers. Centers
without Web sites were excluded. The final study population
consisted of 212 centers with online advertisements for stereo-
tactic radiation. Web sites were evaluated for advertisements
that were inconsistent with advertising guidelines provided by the
American Medical Association.
Results: Most centers (76%) had individual pages dedicated
to the marketing of their brand of stereotactic technology that
frequently contained manufacturer-authored images (50%) or
text (55%). Advertising for the treatment of tumors that have not
been endorsed by professional societies was present on 66% of
Web sites. Centers commonly claimed improved survival (22%),
disease control (20%), quality of life (17%), and toxicity (43%) with
stereotactic radiation. Although 40% of Web sites championed
the center’s regional expertise in delivering stereotactic treat-
ments, only 15% of Web sites provided data to support their
claims.
Conclusion: Provider advertisements for stereotactic radia-
tion were prominent and aggressive. Further investigation of pro-
vider advertising, its effects on quality of care, and potential
oversight mechanisms is needed.
Introduction
Over the past decade, widespread adoption of the Internet has
drastically changed the manner in which health information is
obtained, with patients increasingly turning to Web sites as a
trusted source of medical information.
1-3
A 2010 survey exam-
ining Internet use revealed that 80% of Internet users, which
equates to 59% of American adults, gather their health infor-
mation online.
4
Although greater access to health information
may lead to a more engaged patient population, concerns
abound regarding the prevalence of misinformation on the In-
ternet, particularly in the form of advertising.
5-7
Furthermore,
although direct-to-consumer advertising (DTCA) by pharma-
ceutical and medical device companies has long been strictly
regulated by the US Food and Drug Administration (FDA),
similar practices by health care providers have only recently
been scrutinized.
8
In 2009, the New York Times drew attention
to hospital advertising with an article that exposed the often
emotional and anecdotal nature of these ads.
9
The article
pointed out that the nonprofit status of many hospitals excludes
them from the same FDA oversight as for-profit companies.
New technologies are particularly susceptible to controver-
sial marketing campaigns, as it takes time to fully evaluate safety
and efficacy while companies are eager to see returns on their
investment. In radiation oncology, novel stereotactic radiosur-
gery (SRS) platforms have sparked considerable enthusiasm for
their ability to deliver large doses of radiation to precisely
defined targets. Although SRS was first developed to treat
intracranial lesions, advancements in target localization
through continuous image guidance and increased robotic
mobility have spurred interest in the application of stereo-
tactic treatment to extracranial sites, a procedure known as
stereotactic body radiation therapy (SBRT). Indeed, the use
of SRS and SBRT has surged, with one manufacturer report-
ing worldwide growth rates for intracranial, lung, and pros-
tate tumors of 42%, 80%, and 113% respectively over the
past five years.
10
Yet, whereas SRS has been well studied for
intracranial lesions,
11-16
many clinicians still consider ex-
tracranial SBRT to be experimental in the absence of more
robust, long-term data.
17-22
As illustrated in Table 1, the
most recent Clinical Practice Guidelines of the National
Comprehensive Cancer Network (NCCN) designate inop-
erable lung and liver tumors as the only two approved first-
line indications for SBRT.
23
In addition, a recent position
statement on the use of SBRT for low-to-intermediate risk
prostate cancer by the American Society for Radiation Oncologists
concluded that “there is not sufficient or mature data at this time to
demonstrate equivalency to existing standard treatment modali-
ties.”
24
In light of the uncertain role of SBRT, advertisements by
manufacturers promoting the use of SBRT across multiple body
sites have been controversial.

Notably absent from this discussion has been the role that
hospitals and/or individual providers might play in propagating
such inaccuracies through their own marketing campaigns. We
therefore sought to systematically examine the online advertis-
ing for stereotactic radiation by providers to assess its educa-
tional benefit and explore the prevalence of potentially
misleading information. Given the absence of formal regulation
for determining the bounds of acceptable marketing, we evalu-
ated the Web site advertising of SRS/SBRT by using the Amer-
ican Medical Association (AMA) Code of Ethics, which
includes an Opinion on Advertising and Publicity (Appendix,
online only).
26
These guidelines provide a framework for deter-
mining whether online provider advertising for stereotactic ra-
diation is being conducted in a manner consistent with our
profession’s ethical standards.
Methods
Study Population
We identified two leading manufacturers of stereotactic radio-
surgery technology that produce machines primarily designed
to administer SRS/SBRT treatments and that have been the
subject of criticism for aggressive advertising campaigns. Using
the manufacturer Web sites, we identified all academic hospi-
tals, community hospitals, and private practices in the United
States that provide either of these two brands of stereotactic
technology, counting organizations that had multiple locations
only once (N 215). We excluded two centers that had re-
cently purchased stereotactic equipment and had yet to include
advertisements on their Web sites. We also excluded the Web
site of a large multicenter organization that lacked advertising
because only one of its locations had invested in a stereotactic
radiosurgery system. Our final study population consisted of
212 centers.
Data Collection and Study End Points
All pages of each center’s Web site were fully reviewed using a
predefined scoring sheet designed for prior studies of hospital
advertising.
27
Web sites were scored on the basis of prominence
of advertising, which was assessed by measuring the navigation
depth needed to reach stereotactic radiosurgery-related material
and by noting the presence of a unique webpage dedicated to
the center’s brand of stereotactic technology. Navigation depth
was defined as the number of mouse clicks required to arrive at
a Web page that mentioned the center’s brand of stereotactic
technology, beginning with the Web page of the hospital or
practice where the stereotactic system was located. In addition,
the presence of a link to the manufacturer’s Web site and the use
of manufacturer-provided stock material, as defined by images
or text from the manufacturer Web site, were tracked.
Web sites were also scored on the extent to which the adver-
tising material was consistent with the AMA guidelines on ad-
vertising and publicity, as outlined in Code of Ethics Opinion
5.02.
26
These guidelines state that “objective claims regarding
experience, competence, and the quality of physicians and the
services they provide may be made only if they are factually
supportable.” The guidelines also suggest that “it is unlikely
that a physician will have a truly exclusive or unique skill or
remedy. Claims that imply such a skill or remedy therefore
can be deceptive.” Thus, we focused on whether centers
made factually insupportable or unsubstantiated claims re-
garding (1) the center’s own expertise in using stereotactic
technology or (2) the quality of stereotactic radiation ser-
vices that the center provided.
To analyze whether centers made claims of unique institu-
tional expertise, we tracked those centers that labeled them-
selves as either the regional leader in stereotactic technology or
the region’s first center to implement its use. We also recorded
whether centers supported these claims by detailing the number
of years that they had been offering SRS/SBRT. To analyze
whether centers made unsubstantiated claims regarding the
quality of their stereotactic radiation services, we examined
whether Web sites made statements of improved efficacy, mor-
bidity, and quality of life without providing clinical data or
referencing peer-reviewed publications to support these asser-
tions. Claims of efficacy included implications that SRS/SBRT
represents the standard of care for treatment of certain tumors

(ie, “gold standard,” “most effective,” and so on) or provides a
benefit in either survival (ie, “saves lives,” “cures,” and so on) or
disease control (ie, “more complete eradication of cancer,” “bet-
ter disease control,” and so on). Assertions of decreased mor-
bidity included implications that stereotactic treatment reduces
toxicity (ie, “less complications,” “less risk of infection,” and so
on) or recovery time (ie, “immediate return,” “get back to your
life faster,” and so on). Statements that stereotactic radiation
improves quality of life were also noted. In addition, Web sites
that directly compared outcomes or toxicity with stereotactic
treatment versus with alternative surgical or radiation treatment
options were documented.
Furthermore, we compared the specific tumors that Web
sites advertised as amenable to stereotactic treatment with those
tumors listed by the NCCN as indications for SRS/SBRT. We
chose the NCCN guidelines, which are outlined in Table 1, as
our reference standard because they were the most robust state-
ment from a professional society regarding use of stereotactic
radiation. Thus, we documented whether advertisements for
non-NCCN– endorsed disease sites were characterized as inves-
tigational or as part of a clinical trial. All data were summarized
with simple proportions.
In order to explore the potential impact of practice type on
outcomes, we divided our cohort into academic centers, defined
as the primary center affiliated with a medical school, and non-
academic centers. Outcomes were compared between both
groups by using the two-sample z-test.
Results
Of the 212 centers that constituted our study, 43 (20%) were
academic institutions, and 169 (80%) were community-based
hospitals or private practices. Seventy-five percent of facilities
were operated out of a nonprofit hospital or center. Table 2
summarizes data regarding characteristics of Web site advertis-
ing for SRS/SBRT. One in five centers (19%) highlighted their
brand of stereotactic technology on their Web site’s homepage,
and 39% of centers mentioned their stereotactic technology
within two clicks of the homepage. Most centers (76%) had a
unique Web page dedicated to their stereotactic equipment,
and roughly half of Web sites contained manufacturer-pro-
vided stock images (50%) or stock text (55%). Of the Web sites
that used manufacturer-provided material, only 30% listed the
source. Furthermore, 26% of all Web sites supplied a direct link
to the manufacturer’s homepage.
A majority (66%) of Web sites advertised SBRT as a treat-
ment modality for non-NCCN–designated indications with-
out stating that the use of stereotactic radiation in these
instances is unproven or being conducted on a clinical trial.
These included endorsements of SBRT for spinal (58%), pros-
tate (50%), pancreatic (39%), head and neck (19%), and renal
(15%) cancers, as illustrated in Table 3. Literature supporting
SBRT for these tumor sites was rarely provided, with clinical
data referenced in only 9% of Web sites. In addition to listing
indications for SRS/SBRT, Web sites frequently included a
separate section purporting improved clinical outcomes with
stereotactic treatment. However these sections rarely stipulated
the specific tumors to which these claims applied. Table 3 illus-
trates the prevalence of these claims of clinical benefit, which
included language suggesting that stereotactic radiation im-
proves survival (22%), disease control (20%), and quality of life
(17%). Nineteen percent implied that stereotactic radiation is
the standard of care for certain tumor sites. Claims of shorter
recovery time (77%) and decreased toxicity (43%) were also
common, although specific adverse effects were mentioned in
only 8% of Web sites. AlWhile comparisons to alternative
forms of radiation therapy were rare, a number of Web sites
noted better outcomes with SRS/SBRT versus surgery, partic-
ularly with respect to toxicity (22%). Furthermore, although
40% of centers labeled themselves as the region’s “leader” in
stereotactic services, and 35% claimed to be the first in the
region to acquire stereotactic technology, only 15% of Web
sites provided the actual length of time the center had been
treating patients. This information is summarized in Table 3.
When the data were stratified by academic status, there were
no significant differences in the proportion of center Web sites
in each group that had a dedicated stereotactic radiation page
(P.078), stock images (P.2062), stock text (P.3472),
or a direct link to the manufacturer (P.206). In addition,
average navigation depth was not significantly different (P
.134) between academic and nonacademic centers. There were
also no significant differences in the proportion of centers
claiming to be the regional leader in delivering radiation or the
first to acquire stereotactic technology (P.295). Also, aca-
demic centers did not differ from nonacademic centers in the
proportion of Web sites that maintained advertisements for
non-NCCN–designated indications (data not shown) or that
provided supporting literature or references for their claims
(P.652).
Discussion
Our analysis of health care providers’ advertisements for stereo-
tactic services raises serious questions regarding the transpar-
ency and accuracy of provider DTCA for stereotactic radiation.
Indeed, many of the centers in our study used marketing that

prominently displayed stock industry images and text without
proper attribution. More concerning was the prevalence of un-
substantiated statements and misleading language, which fre-
quently promoted the benefits of SRS/SBRT without providing
evidence to support these claims while also failing to describe
potential risks. In addition, centers commonly labeled them-
selves as the region’s leader in stereotactic services or the first to
offer stereotactic technology, which, even if true, runs counter
to AMA guidelines by implying an ability to offer unique or
exclusive services. Interestingly, these findings seem to apply to
both academic and nonacademic institutions equally. Given the
absence of clinical data, emphasis on institutional expertise, and
claims of improved outcomes compared with alternative treat-
ment options, we found that the advertising campaigns for
stereotactic technology appear to be largely shaped by the com-
petitive market for radiosurgical services rather than a specific
interest in patient education.
We selected stereotactic radiosurgery as the focus of the cur-
rent study because of its expanding role in radiation oncology
and the preliminary nature of the data supporting its use, par-
ticularly for extracranial applications. With advanced opera-
tional capabilities, newer stereotactic radiation platforms have
garnered considerable enthusiasm among radiation oncologists,
and studies across multiple body sites have suggested favorable
survival, toxicity, and quality of life, particularly for brain, lung,
and liver lesions.
11-18
However, most published work to date
has consisted of nonrandomized analyses of small cohorts of
patients without significant follow-up, and some reports have
described unacceptably high toxicity levels, underscoring the
need for caution when advocating the benefits of stereotactic
radiation.
19-22
Without more robust, long-term data, contro-
versy has centered on the promotional language that some man-
ufactures of stereotactic radiation platforms have used in their
DTCA.
25
Rather than focusing on manufacturer DTCA, which has
long been controversial, we instead sought to explore DTCA by
the hospitals and centers that provide stereotactic radiation ser-
vices. Aggressive marketing by health care providers has become
an increasingly recognized phenomenon that threatens the fi-
duciary duty of providers to offer nonbiased assessments of
medical interventions.
28-30
Indeed, a 2005 study of the adver-
tising of 17 leading medical centers revealed that marketing
strategies were frequently based on exploiting emotional ap-
peals and institutional reputation, with rare quantification of
potential benefits or mention of potential harms.
31
The study
also exposed the lack of internal or external measures to regulate
the content of hospital advertisements, a topic more recently
discussed in the popular press.
8,9,32
Although patients generally
exhibit a healthy skepticism of private industry, misleading
DTCA by providers may be particularly worrisome given that
patients often perceive these advertisements to be representative
of the physician perspective.
33,34
Our study suggests that providers need to better ensure that
their advertisements contain accurate and valid information
regarding the risks and benefits of therapies. Furthermore, pro-
viders should seek to distance themselves from medical device
companies by removing links to manufacturer Web sites and
eliminating manufacturer-provided material, or at the very least
acknowledging the source of such material. Providers should
also institute formalized internal processes for evaluating and
approving advertisements. Whereas the institutional review
boards of medical centers are required to approve marketing
materials aimed at recruiting research participants, it is striking
that similar oversight does not exist for advertisements targeted
towards the general population. Recent discussion of these is-
sues at both the Association of American Medical College’s
2010 Group on Institutional Advancement annual meeting
and the NCCNs 2010 annual meeting is encouraging.
8
A number of important limitations of our study must be
acknowledged. First, our analysis was primarily rooted in ethics
using the AMA guidelines to define end points, but future
studies should expand on the possible implications of provider
advertising by examining the effect of this advertising on more

patient-centric end points such as patient education, quality of
care, cost of care, and use of services. Considerable literature
exists on the effect of DTCA by industry on patient education,
patient-physician communication, patient adherence to treat-
ments, and overuse of treatments, and future analysis on pro-
vider advertising should parallel this work.
35
Second, we
examined the advertisements of providers for two brands of
stereotactic technology, and so our results may not be represen-
tative of provider marketing in general. We also included both
hospitals and private practices when assessing the prominence
of advertising, despite the disparity in range of services pro-
vided. In addition, by examining only Web sites, we excluded
other forms of advertising such as print, radio, and television.
Furthermore, our methodology for interpreting and classifying
Web site language was subjective and was constrained by the
fact that Web sites often did not specify tumor sites or differ-
entiate between SRS and SRBT when expounding on the clin-
ical benefits of stereotactic radiation, prohibiting stratification
of our results. Moreover, we used the clinical guidelines of a
single professional society in defining our reference for appro-
priate use of SRS/SBRT. We recognize that the NCCN guide-
lines do not represent a legal standard of care and that use of
SRS/SBRT for non-NCCN–endorsed indications may be le-
gally and/or ethically justifiable given the specific clinical con-
text. Finally, because the NCCN does endorse SBRT for
patients with recurrent spinal metastases who have undergone
prior surgery and/or conventional radiotherapy, but Web sites
rarely clarified the specific patient or tumor characteristics that
would qualified a patient with spinal disease for SBRT, the
percentage of Web sites deemed as advertising a non-NCCN–
designated indication may represent an overestimate.
Nevertheless, by selecting an emerging, expensive technol-
ogy with limited definitive data and using the profession’s eth-
ical code to define end points, we believe our study methods are
sufficient for highlighting an important issue that merits the
attention of providers. Given the extensive literature on the
relative merits of industry DTCA, we believe that similar
attention should also be given to the marketing practices of
providers.
In summary, we found that more than 20% of provider Web
sites advertising stereotactic radiation made unsupported claims
of clinical benefit, 40% championed their own expertise in
delivering stereotactic radiation treatments, and more than
60% endorsed the use of stereotactic radiation for indications
not supported by professional societies. Although the FDA pro-
vides protections against exaggerated advertising by manufac-
turers, consumers have no such protections against aggressive
marketing campaigns by providers. Greater oversight is needed
to ensure that the claims made by providers regarding the ben-
efits of therapies are accurate.

Appendix
American Medical Association Code of Ethics
Opinion 5.02 on Advertising and Publicity
There are no restrictions on advertising by physicians except
those that can be specifically justified to protect the public from
deceptive practices. A physician may publicize him or herself as
a physician through any commercial publicity or other form of
public communication (including any newspaper, magazine,
telephone directory, radio, television, direct mail, or other adver-
tising) provided that the communication shall not be misleading
because of the omission of necessary material information, shall not
contain any false or misleading statement, or shall not otherwise
operate to deceive.
Because the public can sometimes be deceived by the use of
medical terms or illustrations that are difficult to understand,
physicians should design the form of communication to com-
municate the information contained therein to the public in a
readily comprehensible manner. Aggressive, high-pressure ad-
vertising and publicity should be avoided if they create unjus-
tified medical expectations or are accompanied by deceptive
claims. The key issue, however, is whether advertising or pub-
licity, regardless of format or content, is true and not materially
misleading. The communication may include (1) the educa-
tional background of the physician, (2) the basis on which fees
are determined (including charges for specific services), (3)
available credit or other methods of payment, and (4) any other
nondeceptive information.
Nothing in this opinion is intended to discourage or to limit
advertising and representations which are not false or deceptive
within the meaning of Section 5 of the Federal Trade Commis-
sion Act. At the same time, however, physicians are advised that
certain types of communications have a significant potential for
deception and should therefore receive special attention. For
example, testimonials of patients as to the physician’s skill or the
quality of the physician’s professional services tend to be decep-
tive when they do not reflect the results that patients with
conditions comparable to the testimoniant’s condition gener-
ally receive.
Objective claims regarding experience, competence, and the
quality of physicians and the services they provide may be made
only if they are factually supportable. Similarly, generalized
statements of satisfaction with a physician’s services may be
made if they are representative of the experiences of that physi-
cian’s patients.
Because physicians have an ethical obligation to share med-
ical advances, it is unlikely that a physician will have a truly
exclusive or unique skill or remedy. Claims that imply such a
skill or remedy therefore can be deceptive. Statements that a
physician has an exclusive or unique skill or remedy in a
particular geographic area, if true, however, are permissible.
Similarly, a statement that a physician has cured or success-
fully treated a large number of cases involving a particular
serious ailment is deceptive if it implies a certainty of result
and creates unjustified and misleading expectations in pro-
spective patients.
Consistent with federal regulatory standards which apply to
commercial advertising, a physician who is considering the
placement of an advertisement or publicity release, whether in
print, radio, or television, should determine in advance that the
communication or message is explicitly and implicitly truthful
and not misleading. These standards require the advertiser to
have a reasonable basis for claims before they are used in adver-
tising. The reasonable basis must be established by those facts
known to the advertiser, and those which a reasonable, prudent
advertiser should have discovered. Inclusion of the physician’s
name in advertising may help to assure that these guidelines are
being met.

Stereotactic body radiation therapy (SBRT) and stereotactic radiosurgery have become widely used in both palliative and curative treatments for variety of primary and secondary malignancies. Although the indications and use of stereotactic techniques have increased substantially in the past decades, there been no studies to date analyzing public interest in these techniques. Using Google Trends (Google LLC, Mountain View, CA), four search terms ("SBRT," "stereotactic radiosurgery," "Gamma Knife" and "Cyberknife") were analyzed in the U.S. from January 2004 to June 2019. Each term was assigned a relative interest score based on frequency of searches. "SBRT" is becoming an increasingly popular search term, reaching peak interest in October 2018. Conversely, "stereotactic radiosurgery" and "Gamma Knife" radiosurgery initially had high interest, before declining over the past decade. "Cyberknife" was most popular in the mid-2000s but decreased steadily since that time. These trends were subsequently compared against PubMed publication data over the same time.
... Controversial DTCA for new oncology treatments has been previously identified [9,12]. Patients with cancer may be especially vulnerable to controversial marketing due to associated fear and anxiety [11,13]. ...
... The websites of PTCs were evaluated using a standardized data collection form, adapted from previously published studies assessing hospital website DTCA [9,12]. The data collection form is available in Additional file 1: Appendix A. In two instances, two PTC's were represented by a single website; data was collected once for these PTCs. ...

Background: Cancer patients frequently search the Internet for treatment options, and hospital websites are seen as reliable sources of knowledge. Guidelines support the use of proton radiotherapy in specific disease sites or on clinical trials. This study aims to evaluate direct-to-consumer advertising content and claims made by proton therapy centre (PTC) websites worldwide. Methods: Operational PTC websites in English were identified through the Particle Therapy Co-Operative Group website. Data abstraction of website content was performed independently by two investigators. Eight international guidelines were consulted to determine guideline-based indications for proton radiotherapy. Univariate and multivariate logistic regression models were used to determine the characteristics of PTC websites that indicated proton radiotherapy offered greater disease control or cure rates. Results: Forty-eight PTCs with 46 English websites were identified. 60·9% of PTC websites claimed proton therapy provided improved disease control or cure. U.S. websites listed more indications than international websites (15·5 ± 5·4 vs. 10·4 ± 5·8, p = 0·004). The most common disease sites advertised were prostate (87·0%), head and neck (87·0%) and pediatrics (82·6%), all of which were indicated in least one international guideline. Several disease sites advertised were not present in any consensus guidelines, including pancreatobiliary (52·2%), breast (50·0%), and esophageal (43·5%) cancers. Multivariate analysis found increasing number of disease sites and claiming their centre was a local or regional leader in proton radiotherapy was associated with indicating proton radiotherapy offers greater disease control or cure. Conclusions: Information from PTC websites often differs from recommendations found in international consensus guidelines. As online marketing information may have significant influence on patient decision-making, alignment of such information with accepted guidelines and consensus opinion should be adopted by PTC providers.

Full-text available
La validation des traitements de radiothérapie repose sur le calcul de la dose absorbée. Les algorithmes utilisés en routine clinique sont rapides mais limités dans certains cas. Dans ces situations, le calcul Monte-Carlo (MC) reste la référence. Cependant, celui-ci est complexe à mettre en place, et nécessite d'importantes ressources de calcul. Dans ce contexte, ces travaux de thèse ont consisté à élaborer une solution de double calcul MC applicable sur des cas cliniques, et à en étudier les apports. Pour ce faire nous avons développé un package nommé GAMMORA (GAte Monte carlo MOdel for RAdiotherapy). Il comprend la modélisation MC du TrueBeam (Varian) implémenté sur la plateforme GATE, ainsi qu'un script Python permettant de générer automatiquement les macros des simulations pour tous les types de traitements (électrons, VMAT, SRS, SBRT, VMAT-SBRT) à partir des données DICOM du patient. Le modèle étant déjà validé pour des applications simples de faisceaux de photons (X-RTE), nous l'avons complété en y intégrant la modélisation des faisceaux d'électrons (e-RTE) et celles de cas cliniques complexes. En parallélisant les simulations sur le mésocentre de calcul CALMIP, nous atteignons des temps de calcul raisonnables avec une incertitude statistique toujours inférieure à 2% dans les zones d'intérêts (de 10 min pour l'e-RTE à 3 h pour l'X-RTE). Pour éviter l'utilisation de fichiers d'espaces des phases (PHSP) volumineux, nous avons créé et validé un générateur de particules à partir d'un apprentissage profond (GAN) basé sur les PHSP constructeur. Pour l'e-RTE, les applicateurs ont été modélisés pour des champs simples et complexes. Les simulations ont été validées en les comparant aux mesures de référence faites dans l'eau pour les énergies 6, 9, 12, et 18 MeV. Nous avons également comparé les performances de GAMMORA et l'algorithme clinique eMC à des mesures (films radiochromiques) pour un fantôme complexe avec hétérogénéité (os et poumon) ou irrégularité de surface. Les résultats de GAMMORA étaient supérieurs ou équivalents à ceux d'eMC dans presque toutes les configurations. L'étude de cas cliniques a aussi montré des écarts de distributions de dose importants entre les deux algorithmes (particulièrement dans les régions de hautes densités). Une étude de l'effet interplay (IE) a ensuite été réalisée. Tout d'abord, des mesures ont été réalisées à l'aide d'un fantôme de contrôle qualité (Octavius 4D) placé sur une plateforme de mouvement 3D programmable. Il s'agissait d'abord d'évaluer qualitativement l'IE pour quelques configurations. Ensuite, ces dernières ainsi que 300 autres ont été simulées à l'aide de GAMMORA pour étudier l'IE de façon extensive en modifiant différents paramètres physiques (période, amplitude et forme du mouvement, dose par fraction ou marges de sécurité). Une méthodologie adaptée nous a permis d'isoler l'IE du blurring. [...]
... Although the influence of these drug industry practices on physician prescribing patterns has been recognized and is regulated under both the federal anti-kickback statute and the Sunshine Act, this history may not be familiar to patients, families and nonphysician practitioners who treat eating disorders. Combined with the relative dearth of healthcare related outcomes from intensive treatment programs for eating disorders, these marketing practices raise ethical questions and concerns about quality and cost of care (Friedman et al., 2016;Guarda et al., 2017) that have been broadly linked to privatization of healthcare in the U.S. and worldwide (Bachhuber, Southern, & Cunningham, 2014;Herrera, Rada, Kuhn-Barrientos, & Barrios, 2014;Narang et al., 2013;Segal & Siver-Greenberg, 2018) . ...
Article
In the United States, the past decade has seen rapid growth in treatment centers providing specialty care to patients with eating disorders. Much of this growth has been in higher levels of care, including hospital‐based and residential treatment. Despite this expansion, there remains lack of agreement regarding the most important components of care, such as staff training or specifics of treatment delivery. Additionally there is no consensus on how best to assess outcome and compare performance across programs. This leaves patients, families, public and private insurance programs, and policy makers with limited information to help facilitate treatment decisions. The present paper considers implications of these changes in the eating disorder treatment landscape and examines two ideas that, if implemented, may enhance the quality of eating disorder care. First, we explore the proposal to develop a network of centers of excellence in eating disorder treatment and the value this may have for improving overall treatment quality. This idea was discussed at an expert meeting held at SAMSHA in 2017 regarding issues important to the field following passage of the 21st Century Cures Act. Second, we consider the potential utility of a study using the Delphi method to promote expert consensus regarding clinical outcome assessments.

Importance Manufacturers, companies, and health care professionals and organizations use an array of promotional activities to sell and increase market share of their products and services. These activities seek to shape public and clinician beliefs about laboratory testing, the benefits and harms of prescription drugs, and some disease definitions. Objective To review the marketing of prescription drugs, disease awareness campaigns, health services, and laboratory tests and the related consequences and regulation in the United States over a 20-year period (1997-2016). Evidence Analysis (1997-2016) of consumer advertising (Kantar Media data for spending and number of ads); professional marketing (IQVIA Institute for Human Data Science, Open Payments Data [Centers for Medicare & Medicaid Services]); regulations and legal actions of the US Food and Drug Administration (FDA), Federal Trade Commission (FTC), state attorneys general, and US Department of Justice; and searches (1975-2018) of peer-reviewed medical literature (PubMed), business journals (Business Source Ultimate), and news media (Lexis Nexis) for articles about expenditures, content, and consequences and regulation of consumer and professional medical marketing. Spending is reported in 2016 dollars. Findings From 1997 through 2016, spending on medical marketing of drugs, disease awareness campaigns, health services, and laboratory testing increased from 17.7to17.7 to 29.9 billion. The most rapid increase was in direct-to-consumer (DTC) advertising, which increased from 2.1billion(11.92.1 billion (11.9%) of total spending in 1997 to 9.6 billion (32.0%) of total spending in 2016. DTC prescription drug advertising increased from 1.3billion(79000ads)to1.3 billion (79 000 ads) to 6 billion (4.6 million ads [including 663 000 TV commercials]), with a shift toward advertising high-cost biologics and cancer immunotherapies. Pharmaceutical companies increased DTC marketing about diseases treated by their drugs with increases in disease awareness campaigns from 44 to 401 and in spending from 177millionto177 million to 430 million. DTC advertising for health services increased from 542millionto542 million to 2.9 billion, with the largest spending increases by hospitals, dental centers, cancer centers, mental health and addiction clinics, and medical services (eg, home health). DTC spending on advertising for laboratory tests (such as genetic testing) increased from 75.4millionto75.4 million to 82.6 million, although the number of ads increased more substantially (from 14 100 to 255 300), reflecting an increase in less expensive electronic media advertising. Marketing to health care professionals by pharmaceutical companies accounted for most promotional spending and increased from 15.6billionto15.6 billion to 20.3 billion, including 5.6billionforprescriberdetailing,5.6 billion for prescriber detailing, 13.5 billion for free samples, 979millionfordirectphysicianpayments(eg,speakingfees,meals)relatedtospecificdrugs,and979 million for direct physician payments (eg, speaking fees, meals) related to specific drugs, and 59 million for disease education.

From 1997 through 2016, the number of consumer and professional drug promotional materials that companies submitted for FDA review increased from 34 182 to 97 252, while FDA violation letters for misleading drug marketing decreased from 156 to 11. Since 1997, 103 financial settlements between drug companies and federal and state governments resulted in more than 11 billion in fines for off-label or deceptive marketing practices. The FTC has acted against misleading marketing by a single for-profit cancer center. Conclusions and Relevance Medical marketing increased substantially from 1997 through 2016, especially DTC advertising for prescription drugs and health services. Pharmaceutical marketing to health professionals accounted for most spending and remains high even with new policies to limit industry influence. Despite the increase in marketing over 20 years, regulatory oversight remains limited.

Objective: To evaluate the quality of information presented and claims made on websites offering bioidentical hormone therapy (BHT) products or services. Methods: A quantitative content analysis was completed on 100 websites promoting or offering BHT products or services. Websites were identified through Google search engine from September to October 2013. Search terms included "bioidentical hormone therapy" or "bioidentical progesterone," accompanied by "purchase or buy," "service," or "doctors." The Brief DISCERN instrument was used to determine the quality of the health information. Results: Websites were from Canada (59%), United States (38%), and other countries (3%). Almost half of the websites originated from medical clinics (47%), and healthcare professionals offering BHT services included physicians (50%), pharmacists (19%), and naturopaths (16%). Majority of websites promoted BHT as custom-compounded formulations (62%), with only 27% indicating that BHT is also commercially available. Websites overall claimed that BHT had less risk compared with conventional hormone therapy (62%). BHT was described as having less breast cancer risk (40%), whereas over a quarter of websites described BHT as "protective" for breast cancer. Websites mainly targeted women (99%), with males mentioned in 62% of websites. Product descriptors used to promote BHT included individualization (77%), natural (70%), hormone imbalance (56%), and antiaging (50%). The mean Brief DISCERN score was 15, indicating lower quality of information. Conclusions: Claims made about BHT on the internet are misleading and not consistent with current professional organizations' recommendations. Understanding how BHT may be promoted on the internet can help healthcare professionals when educating patients.

Introducing the topic of comparative effectiveness for prostate cancer treatments with a reminder of the disease's heterogeneity risks tautology. However, the profound variation both in this cancer's biology and its clinical course is increasingly widely recognized, while management alternatives for clinically localized prostate cancer have exploded. Available options now include active surveillance, multiple surgical approaches to prostatectomy, various forms of external-beam and interstitial radiation, and a growing list of energy ablative technologies. Each treatment option has its own efficacy rate as well as its own set of complications, side effects and financial costs. Difficulties comparing these options, together with the high prevalence of the disease, led the Institute of Medicine to include localized prostate cancer among the top 25 priority conditions for future comparative effectiveness research. The sheer volume of possible treatment options, with their individual risks and benefits, can be confusing for patients and clinicians to research, understand and explain. To help clinicians navigate these treatment options, we have assembled this Urologic Oncology Seminar on the comparative effectiveness of treatments for clinically localized prostate cancer. The articles focus on high quality evidence-based medicine and most have included useful tables summarizing seminal trials and available resources.

Communication researchers, recognizing the message sent is not necessarily the same as the message received, have incorporated the perspective of advertising professionals into the study of advertising effects. Health marketing research could similarly benefit from incorporating this largely absent perspective into the academic and policy debate surrounding the impact of advertising on health issues ranging from obesity to alcohol use. This commentary serves as a call to action to stakeholders in this academic and policy debate: focus on the perspective of advertising professionals to enrich health marketing and public health research in which advertising is the delivery vehicle for health messages.

Plant water deficits during flowering came maize (Zea mays L.) kernels to abort. Lack of current and reserve photosynthate account for much of the kernel toss, but partitioning to ovaries at low ovary water potential (psi(w)) may also be limited by lack of assimilate demand. To test this possibility, we measured the water status, carbohydrate content, and growth elf ovaries on plants grown in the field in pots containing 22 kg of soil under one of three light environments [Control, 75-cm rows, 43 055 plants ha(-1); Shade, same as Control except under shade cloth (55% light interception) from the sixth leaf stage until physiological maturity; or Isolated, 122-cm rows, 6727 plants ha(-1)] and exposed to a water deficit during pollination. Water was withheld at silk emergence and plants were hand-pollinated 4 d later when silk psi(w) was approximate to - 1.1 MPa, leaf psi(w) was approximate to - 1.8 MPa, and photosynthesis was completely inhibited. The water deficit decreased kernel set, which was correlated with the inhibition of ovary dry matter accumulation. The concentration of sucrose and glucose increased in ovaries of water-deficient plants, and ovary turgor remained at or above control levels. Thus, inhibition of ovary growth at low psi(w) was not related to a loss of turgor, nor was it caused by a depletion of ovary sugars. Sugar accumulation at low psi(w) suggested that metabolism may have been impaired. Coupled with a low level of reserves, failure to utilize available sugars at low psi(w) would severely inhibit assimilate flux to the ear and render kernel set highIy vulnerable to water deficits during pollination.

Hypofractionated, stereotactic body radiotherapy (SBRT) is an emerging treatment approach for prostate cancer. We present the outcomes for low-risk prostate cancer patients with a median follow-up of 5 years after SBRT. Between Dec. 2003 and Dec. 2005, a pooled cohort of 41 consecutive patients from Stanford, CA and Naples, FL received SBRT with CyberKnife for clinically localized, low-risk prostate cancer. Prescribed dose was 35-36.25 Gy in five fractions. No patient received hormone therapy. Kaplan-Meier biochemical progression-free survival (defined using the Phoenix method) and RTOG toxicity outcomes were assessed. At a median follow-up of 5 years, the biochemical progression-free survival was 93% (95% CI = 84.7% to 100%). Acute side effects resolved within 1-3 months of treatment completion. There were no grade 4 toxicities. No late grade 3 rectal toxicity occurred, and only one late grade 3 genitourinary toxicity occurred following repeated urologic instrumentation. Five-year results of SBRT for localized prostate cancer demonstrate the efficacy and safety of shorter courses of high dose per fraction radiation delivered with SBRT technique. Ongoing clinical trials are underway to further explore this treatment approach.

PURPOSE To compare Google (www.google.com) to other web-based resources for identifying specific medical information. METHOD AND MATERIALS A 10-question multiple-choice test was designed using information from medical textbooks to cover uncommon diseases, diagnostic tests, procedures or devices. Medical student volunteers were randomized to complete the exam either (1) using Google or (2) using any web resource(s) except Google, and tally the number of links viewed to answer the question. Participants repeated the exam with the alternative arm 2 weeks later, providing data for paired comparison of Google to alternative resources used. Measures included efficiency (based on number of links viewed) and correctness (correct/total answers). Results based on individual websites and search engines used were also compiled for comparison across resources. For Google searches, the sites that ultimately provided the information ("end-sites") were categorized. RESULTS Eighty-nine medical students completed the protocol. Paired analysis showed that Google was more efficient compared to all alternatives (mean links 1.50 vs 1.94, p=0.002), with no significant difference in correctness (26/843 or 3.1% vs 35/843 or 4.2% incorrect answers). Following a Google search, 89% of end-sites identified that provided correct answers were medical websites (e.g. eMedicine, Merck), National Library of Medicine resources, journal articles or dictionary/encyclopedia sites. The most frequent alternatives used to initiate a search were the search engines Yahoo & Ask, and the encyclopedia Wikipedia. Yahoo yielded comparable correctness to Google (96% vs. 97%), but was less efficient (mean links 1.90 vs 1.54, p<0.001). Non-google search engines were more efficient than other resources (e.g. medical websites, Wikipedia, Pubmed) (mean links 1.87 vs 2.66, p=0.002). Used for 10 searches, Pubmed required a mean of 4.25 links to find the correct answer. CONCLUSION Google quickly identifies specific medical information located in web-based medical resources. CLINICAL RELEVANCE/APPLICATION Physicians seeking a specific piece of medical information online should consider initiating searches with Google, which provides a list of medical resources likely to contain the information needed.

This paper reviews the empirical evidence of the effect of credibility of the message source on persuasion over a span of 5 decades, primarily to come up with recommendations for practitioners as to when to use a high- or a low-credibility source and secondarily to identify areas for future research. The main effect studies of source credibility on persuasion seem to indicate the superiority of a high-credibility source over a low-credibility one. Interaction effect studies, however, show source credibility to be a liability under certain conditions. The variables found to interact with source credibility are categorized into 5 categories: source, message, channel, receiver, and destination variables. The most heavily researched variables have been the message and receiver variables. Implications for marketers/advertisers and suggestions for future research are discussed.

To examine the prevalence and content of robotic surgery information presented on websites of U.S. hospitals. We completed a systematic analysis of 400 randomly selected U.S. hospital websites in June of 2010. Data were collected on the presence and location of robotic surgery information on a hospital's website; use of images or text provided by the manufacturer; use of direct link to manufacturer website; statements of clinical superiority; statements of improved cancer outcome; mention of a comparison group for a statement; citation of supporting data and mention of specific risks. Forty-one percent of hospital websites described robotic surgery. Among these, 37% percent presented robotic surgery on their homepage, 73% used manufacturer-provided stock images or text, and 33% linked to a manufacturer website. Statements of clinical superiority were made on 86% of websites, with 32% describing improved cancer control, and 2% described a reference group. No hospital website mentioned risks. Materials provided by hospitals regarding the surgical robot overestimate benefits, largely ignore risks and are strongly influenced by the manufacturer.

This study examines whether cancer patients' Internet use leads them to prefer a more active role in medical decision making and whether the effects of Internet use on active participation preferences vary according to patients' education levels. Randomly drawn sample (N=2013) from the Pennsylvania Cancer Registry, comprised of breast, prostate, and colon cancer patients, completed mail surveys in the fall of 2006 (overall response rate=64%). Of 2013 baseline respondents, 85% agreed to participate in follow-up survey (N=1703). Of those who agreed, 76% (N=1293) completed follow-up surveys in the fall of 2007. Cancer patients' Internet use for health information at wave one led them to want to be more active participants in medical decision making at wave two (β=.06, p<.05). This applied to all cancer patients regardless of their education levels. Higher levels of Internet use among cancer patients may lead patients to want to be more actively involved in medical decision making. Considering the beneficial effects of patients' active participation in medical decision making, it will be worthwhile for health educators to recommend Internet use to cancer patients.
