[show abstract] [hide abstract]
ABSTRACT: Purpose/Objectives: To identify women's information and communication preferences about treatment-focused genetic testing (TFGT) in the ovarian cancer context.Research Approach: A qualitative interview study.Setting: Two familial cancer services and a gynecologic oncology clinic at a major teaching hospital in Australia.Participants: 22 women diagnosed with ovarian cancer who had either advanced disease and had previously undergone TFGT (n = 12) or had been diagnosed in the previous 6-20 weeks with ovarian cancer and had not undergone TFGT (n = 10).Methodologic Approach: Participants were interviewed individually about actual and hypothetical views of TFGT. The interviews were transcribed and organized into themes using qualitative analysis software.Findings: Most women wanted to be informed about TFGT prior to their surgery for ovarian cancer. The majority preferred to receive the information verbally; slightly more women preferred their medical oncologist to deliver the information compared to a genetic specialist or oncology nurse. Women preferred the focus of pretest information to be on them and their treatment.Conclusions: Women diagnosed with ovarian cancer want information about genetic testing early with focus placed on the potential benefits of genetic testing on treatment.Interpretation: The findings of this study provide much-needed guidance to oncology nurses and other oncology healthcare professionals about when, what, and how information about TFGT should be delivered to patients diagnosed with ovarian cancer. Supportive patient education materials now need to be developed to assist these women in making informed decisions about genetic testing.Knowledge Translation: Knowing that women do want TFGT, how they want it presented and by whom, and the content and level of detail that women want means that TFGT can now be presented as an option to women newly diagnosed with ovarian cancer, which may influence firstline treatment. The findings also provide the knowledge required to prepare education tools to assist oncology nurses involved in frontline care.Oncology Nursing Forum 05/2013; 40(3):275-83. · 1.91 Impact Factor -
Article: The Acceptability, Feasibility, and Efficacy (Phase I/II Study) of the OVERcome (Olive Oil, Vaginal Exercise, and MoisturizeR) Intervention to Improve Dyspareunia and Alleviate Sexual Problems in Women with Breast Cancer.
[show abstract] [hide abstract]
ABSTRACT: INTRODUCTION: Almost half of breast cancer survivors experience chronic sexual problems. Despite the negative effects of dyspareunia on physical and overall quality of life, sexual dysfunction remains underreported and undertreated in clinical practice. This is likely due to the paucity of evidence-based interventions to improve sexual functioning. AIM: The study aims to prospectively evaluate the acceptability, feasibility, and efficacy of a novel intervention (Olive Oil, Vaginal Exercise, and MoisturizeR [OVERcome]) to improve sexual problems following breast cancer treatment. MAIN OUTCOME MEASURES: Dyspareunia, sexual functioning, quality of life, distress, and pelvic floor muscles (PFMs) functioning were evaluated. METHODS: Twenty-five women with dyspareunia were instructed to perform pelvic floor muscle (PFM) relaxation exercises twice/day to prevent/manage PFM overactivity, apply a polycarbophil-based vaginal moisturizer three times/week to alleviate vaginal dryness, use olive oil as a lubricant during intercourse, and complete a weekly compliance diary. PFM relaxation training was administered by a physiotherapist at weeks 0 and 4, with follow-up at weeks 12 and 26. At each visit, women completed validated self-report questionnaires and the physiotherapist recorded objective measures of PFM functioning. RESULTS: OVERcome resulted in significant improvements in dyspareunia, sexual function, and quality of life over time (all P < 0.001). PFM relaxation training was reported to be effective (P ≤ 0.001). Maximum benefits were observed at week 12. Most women rated PFM relaxation exercises (92%), vaginal moisturizer (88%), and olive oil (73%) as helpful, indicating that the intervention was acceptable. Unexpectedly, six cases (11%) of vaginal stenosis were noted during initial screening. CONCLUSIONS: This novel intervention is acceptable to patients with demonstrated efficacy in improving dyspareunia and sexual function following breast cancer. Delivery of the OVERcome intervention appears feasible in a clinical setting, providing a potential treatment for this important clinical issue. The unexpected number of observed cases of stenosis further highlights the underreporting of sexual problems in this population, deserving further exploration.

Article: LRP1B deletion in high-grade serous ovarian cancers is associated with acquired chemotherapy resistance to liposomal doxorubicin.
[show abstract] [hide abstract]
ABSTRACT: High-grade serous cancer (HGSC), the most common subtype of ovarian cancer, often becomes resistant to chemotherapy, leading to poor patient outcomes. Intratumoral heterogeneity occurs in nearly all solid cancers, including ovarian cancer, contributing to the development of resistance mechanisms. In this study, we examined the spatial and temporal genomic variation in HGSC using high-resolution single-nucleotide polymorphism arrays. Multiple metastatic lesions from individual patients were analyzed along with 22 paired pretreatment and posttreatment samples. We documented regions of differential DNA copy number between multiple tumor biopsies that correlated with altered expression of genes involved in cell polarity and adhesion. In the paired primary and relapse cohort, we observed a greater degree of genomic change in tumors from patients that were initially sensitive to chemotherapy and had longer progression-free interval compared with tumors from patients that were resistant to primary chemotherapy. Notably, deletion or downregulation of the lipid transporter LRP1B emerged as a significant correlate of acquired resistance in our analysis. Functional studies showed that reducing LRP1B expression was sufficient to reduce the sensitivity of HGSC cell lines to liposomal doxorubicin, but not to doxorubicin, whereas LRP1B overexpression was sufficient to increase sensitivity to liposomal doxorubicin. Together, our findings underscore the large degree of variation in DNA copy number in spatially and temporally separated tumors in HGSC patients, and they define LRP1B as a potential contributor to the emergence of chemotherapy resistance in these patients.Cancer Research 08/2012; 72(16):4060-73. · 7.86 Impact Factor -
Article: How should we discuss genetic testing with women newly diagnosed with breast cancer? Design and implementation of a randomized controlled trial of two models of delivering education about treatment-focused genetic testing to younger women newly diagnosed with breast cancer.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Germline BRCA1 and BRCA2 mutation testing offered shortly after a breast cancer diagnosis to inform women's treatment choices - treatment-focused genetic testing 'TFGT' - has entered clinical practice in specialist centers and is likely to be soon commonplace in acute breast cancer management, especially for younger women. Yet the optimal way to deliver information about TFGT to younger women newly diagnosed with breast cancer is not known, particularly for those who were not suspected of having a hereditary breast cancer syndrome prior to their cancer diagnosis. Also, little is known about the behavioral and psychosocial impact or cost effectiveness of educating patients about TFGT. This trial aims to examine the impact and efficiency of two models of educating younger women newly diagnosed with breast cancer about genetic testing in order to provide evidence for a safe and effective future clinical pathway for this service. DESIGN/METHODS: In this non-inferiority randomized controlled trial, 140 women newly diagnosed with breast cancer (aged less than 50 years) are being recruited from nine cancer centers in Australia. Eligible women with either a significant family history of breast and/or ovarian cancer or with other high risk features suggestive of a mutation detection rate of > 10% are invited by their surgeon prior to mastectomy or radiotherapy. After completing the first questionnaire, participants are randomized to receive either: (a) an educational pamphlet about genetic testing (intervention) or (b) a genetic counseling appointment at a family cancer center (standard care). Each participant is offered genetic testing for germline BRCA mutations. Decision-related and psychosocial outcomes are assessed over 12 months and include decisional conflict (primary outcome);uptake of bilateral mastectomy and/or risk-reducing salpingo-oophorectomy; cancer-specific- and general distress; family involvement in decision making; and decision regret. A process-oriented retrospective online survey will examine health professionals' attitudes toward TFGT; a health economic analysis will determine the cost effectiveness of the intervention. DISCUSSION: This trial will provide crucial information about the impact, efficiency and cost effectiveness of an educational pamphlet designed to inform younger women newly diagnosed with breast cancer about genetic testing. Issues regarding implementation of the trial are discussed. TRIAL REGISTRATION: The study is registered with the Australian and New Zealand Clinical Trials Group (Registration no: ACTRN12610000502033).BMC Cancer 07/2012; 12(1):320. · 3.01 Impact Factor
