Pancreatic cancer is the fourth most common cancer in both men and women in the United States. It has the lowest survival rate of all cancers, largely due to the presence of non-specific symptoms, leading to diagnosis at advanced stages. While the majority of cases of pancreatic cancer are sporadic, up to 10% may be associated with an inherited predisposition. Currently, there is no standard screening protocol for pancreatic cancer, although this will change in the future as technology improves. Additionally, there is little information regarding the perceptions and intent to screen for pancreatic cancer among those with an increased risk due to a hereditary cancer predisposition syndrome, which was the objective of this study. Focus groups and individual telephone interviews were conducted, with questions focused on knowledge about pancreatic cancer and screening, perceived motivators, and perceived barriers related to each of the screening techniques currently available. Participants were recruited from the High Risk Breast Cancer and Pancreatic Cancer Registries at Huntsman Cancer Institute. The findings of this study indicated that individuals from these high-risk groups have low knowledge levels of pancreatic cancer screening, despite their desire for this information. Motivation to undergo a particular screening technique is related to whether the test is recommended by a physician, cost, degree of invasiveness, and comfort level. This information is useful to genetics professionals who counsel at-risk individuals, physicians who formulate patient care plans, and translational researchers who are developing pancreatic screening methods.

- "EUS). These findings are consistent with qualitative data reported by Lewis  and are important with regard to developing early detection methods that will be acceptable to the individuals for whom they are intended. Previous studies including highly-selected, at-risk individuals have reported actual uptake of PC screening ranging between 61% (for EUS) and 67% (for MRI), which reflects variation in individual preferences and provides evidence that uptake cannot always be assumed [6,8].

ABSTRACT: Pancreatic cancer (PC) is considered the most lethal cancer and approximately 10% of PC is hereditary. The purpose of the study was to assess attitudes of at-risk family members with two or more relatives affected with pancreas cancer (PC) toward PC risk and future screening options.
At-risk family members and primary care controls were surveyed regarding perceived PC risk, PC worry/concern, attitude toward cancer screening, screening test accuracy, and intentions regarding PC screening via blood testing or more invasive endoscopic ultrasound (EUS).
PC family members reported greater perceived risk of PC than controls (54% vs. 6%, respectively, p < 0.0001). PC family members also reported higher levels of PC worry/concern than controls (p < 0.0001), although 19% of PC family members indicated they were "not at all concerned" about getting PC. PC family members indicated greater acceptance of a false-negative result on a PC screening test relative to controls (12% vs. 8%, p = 0.02). Both groups reported high (>89%) receptivity to the potential PC screening options presented, though receptivity was greater among PC family members as compared to controls (p < 0.0001) for EUS. In multivariable analyses, degree of PC concern (p < 0.0001) was associated with intention to screen for PC by blood test and EUS, while perceived PC risk was associated with likelihood of undergoing EUS only (p < 0.0001).
Receptivity to screening options for PC appears high. Clinicians should address behavioral and genetic risk factors for PC and foster appropriate concern regarding PC risk among at-risk individuals.

ABSTRACT: Expanding the existing Breast Cancer Family Registry (BCFR) to enrol daughters aged 6-17 years in a prospective cohort study named LEGACY (Lessons in Epidemiology and Genetics of Adult Cancer from Youth) offers the opportunity to study the effects of genetic and environmental exposures in youth on adult breast cancer risk. Few studies have assessed parents' willingness to enroll their daughters in genetic epidemiological cohort studies. Since BCFR parents are the gatekeepers of their daughters' future enrollment, it is important to explore their interests and attitudes towards LEGACY.
Semi-structured telephone interviews were conducted with 85 BCFR participant parents at 3 BCFR sites in Ontario, Canada, and in Utah and Northern California. We explored parents' thoughts and feelings (interests and attitudes) regarding their daughters' enrollment in LEGACY and different data collection modalities. Qualitative analysis of audiotaped interviews was carried out utilizing an inductive content analysis.
Parents' acceptance of three data collection modalities were 92% (78/85) for questionnaire data, 87% (74/85) for biological samples and 63% (46/73) for physical examination for pubertal staging. The parents' primary motivation for participation was altruistic. Their concerns regarding their daughters' participation centered on exacerbating awkward pubertal feelings, increasing cancer anxiety, respecting autonomy and maturity, privacy and future use of data and logistical impediments.
Parents demonstrated a high level of interest in the creation of LEGACY. Their motivation to participate was balanced by their desire to protect daughters from undue harm. These interviews contributed valuable information for the design of LEGACY.

ABSTRACT: : The success of any surveillance program depends not solely on its technological aspects but also on the commitment of participants to adhere to follow-up investigations, which is influenced by the psychological impact of surveillance. This study investigates the psychological impact of participating in a pancreatic cancer surveillance program.
: High-risk individuals participating in an endoscopic ultrasonography-magnetic resonance imaging-based pancreatic cancer surveillance program received a questionnaire assessing experiences with endoscopic ultrasonography and magnetic resonance imaging, reasons to participate, psychological distress, and benefits and barriers of surveillance. High-risk individuals were individuals with a strong family history of pancreatic cancer or carriers of pancreatic cancer-prone gene mutations.
: Sixty-nine participants (85%) completed the questionnaire. Surveillance was reported as "very to extremely uncomfortable" by 15% for magnetic resonance imaging and 14% for endoscopic ultrasonography. Most reported reason to participate was that pancreatic cancer might be detected in a curable stage. Abnormalities were detected in 27 respondents, resulting in surgical resection in one individual and a shorter follow-up interval in five individuals. Surveillance outcomes did not influence cancer worries. Overall, 29% was "often" or "almost always" concerned about developing cancer. Six respondents (9%) had clinical levels of depression and/or anxiety. According to 88% of respondents, advantages of surveillance outweighed disadvantages.
: Although endoscopic ultrasonography is more invasive than magnetic resonance imaging, endoscopic ultrasonography was not perceived as more burdensome. Despite one third of respondents worrying frequently about cancer, this was not related to the surveillance outcomes. Anxiety and depression levels were comparable with the general population norms. Advantages of participation outweighed disadvantages according to the majority of respondents. From a psychological point of view, pancreatic cancer surveillance in high-risk individuals is feasible and justified.
