Oncologist-led BRCA 'mainstreaming' in the ovarian cancer clinic: A study of 255 patients and its impact on their management.

ABSTRACT: Although guidelines recommend BRCA testing for all women with non-mucinous epithelial ovarian cancer, there is significant variability in access to testing across the UK. A germline BRCA mutation (BRCAm) in ovarian cancer patients provides prognostic and predictive information and influences clinical management, such as the use of PARP inhibitors, which have demonstrated a progression-free survival benefit in the BRCAm cohort. Additionally, the finding of a BRCAm has significant implications for patients and their families in terms of cancer risk and prevention. We studied the impact of a newly-formed, oncologist-led 'mainstreaming' germline BRCA testing pathway in 255 ovarian cancer patients at Imperial College NHS Trust. Prior to the establishment of 'mainstreaming', uptake of germline BRCA testing was 14% with a mean turnaround time of 148.2 calendar days. The 'mainstreaming' approach led to a 95% uptake of germline BRCA testing and a mean turnaround time of 20.6 days. Thirty-four (13.33%) BRCAm patients were identified. At the time of data collection nine BRCAm patients had received a PARP inhibitor off-trial, three had entered a PARP inhibitor trial and 5 were receiving platinum-based chemotherapy with a plan to receive PARP inhibitor maintenance. This study provides further evidence of the impact of oncologist-led 'mainstreaming' programs.

Project description:Purpose There is a growing demand for BRCA1/ 2 mutation ( BRCAm) testing in patients with ovarian cancer; however, the limited number of genetic counselors presents a potential barrier. To facilitate more widespread BRCAm testing in ovarian cancer, pretest counseling by the oncology team could shorten testing turnaround times and ease the pressure on genetic counselors. Patients and Methods The prospective, observational Evaluating a Streamlined Onco-genetic BRCA Testing and Counseling Model Among Patients With Ovarian Cancer (ENGAGE) study evaluated a streamlined, oncologist-led BRCAm testing pathway. The analysis population comprised 700 patients with ovarian cancer at 26 sites in the United States, Italy, and Spain. The primary objectives were to assess turnaround time and, using questionnaires, to evaluate stakeholder satisfaction (patients, oncologists, and geneticists or genetic counselors) with the oncologist-led BRCAm testing pathway. Results The median overall turnaround time was 9.1 weeks (range, 0.9 to 37.1 weeks), with median turnaround times in the United States, Italy, and Spain of 4.1 weeks (range, 0.9 to 37.1 weeks), 20.4 weeks (range, 2.9 to 35.4 weeks), and 12.0 weeks (range, 2.0 to 36.7 weeks), respectively. Patient satisfaction with the oncologist-led BRCAm testing pathway was high, with > 99% of patients expressing satisfaction with pre- and post- BRCAm test counseling. Oncologist satisfaction with the BRCAm testing pathway was also high, with > 80% agreeing that the process for performing BRCAm testing worked well and that counseling patients on BRCAm testing was an efficient use of their time. Oncologists expressed higher levels of satisfaction with the BRCAm testing pathway than did geneticists or genetic counselors. Conclusion The results of the ENGAGE study demonstrate that an oncologist-led BRCAm testing process is feasible in ovarian cancer. Development of local BRCAm testing guidelines similar to the one used in this study could allow faster treatment decisions and better use of resources in the management of patients with ovarian cancer.

Project description:We have analyzed the histopathological, clinical, and genetic characteristics in hereditary breast and ovarian cancer patients of counselled families from 1996 up to today in the southwestern Finland population. In this study we analyzed the incidence of different BRCA1 and BRCA2 pathogenic variants (PV). 1211 families were evaluated, and the families were classified as 38 BRCA1 families, 48 BRCA2 families, 689 non-BRCA families and 436 other counselled families (criteria for genetic testing was not met). In those families, the study consisted of 44 BRCA1 breast and/or ovarian cancer patients, 58 BRCA2 cancer patients, 602 non-BRCA patients and 328 other counselled patients. Breast cancer mean onset was 4.6 years earlier in BRCA1 carriers compared to BRCA2 (p = 0.07, a trend) and ovarian cancer onset almost 11 years earlier in BRCA1 families (p < 0.05). In BRCA families the onset of ovarian cancer was later than 40 years, and BRCA2-origin breast cancer was seen as late as 78 years. The BRCA PV (9%) increases the risk for same patient having both ovarian and breast cancer with a twofold risk when compared to non-BRCA group (4%) (95% CI p < 0.05). Triple-negativity in BRCA1 (42%) carriers is approximately 2.6 times vs more common than in BRCA2 carriers (16%) (p < 0.05). The risk ratio for bilateral breast cancer is approximately four times when compared BRCA2 (17%) and other counselled patients' group (4%) (p < 0.05). 27% southwestern BRCA2-families have a unique PV, and correspondingly 39% of BRCA1-families. The results of this analysis allow improved prediction of cancer risk in high-risk hereditary breast and ovarian families in southwestern Finland and improve long term follow-up programs. According to the result it could be justified to have the discussion about prophylactic salpingo-oophorectomy by the age of 40 years. The possibility of late breast cancer onset in BRCA2 carriers supports the lifelong follow-up in BRCA carriers. Cancer onset is similar between BRCA2 carries and non-BRCA high-risk families. This study evaluated mutation profile of BRCA in southwestern Finland. In this study genotype-phenotype correlation was not found.

Project description:BackgroundBreast cancer is the world's most common cancer among women. It is becoming an increasingly urgent problem in low- and middle-income countries (LMICs) where a large fraction of women is diagnosed with advanced-stage disease and have no access to treatment or basic palliative care. About 5-10% of all breast cancers can be attributed to hereditary genetic components and up to 25% of familial cases are due to mutations in BRCA1/2 genes. Since their discovery in 1994 and 1995, as few as 18 mutations have been identified in BRCA genes in the Tunisian population. The aim of this study is to identify additional BRCA mutations, to estimate their contribution to the hereditary breast and ovarian cancers in Tunisia and to investigate the clinicopathological signatures associated with BRCA mutations.MethodsA total of 354 patients diagnosed with breast and ovarian cancers, including 5 male breast cancer cases, have been investigated for BRCA1/2 mutations using traditional and/or next generation sequencing technologies. Clinicopathological signatures associated with BRCA mutations have also been investigated.ResultsIn the current study, 16 distinct mutations were detected: 10 in BRCA1 and 6 in BRCA2, of which 11 are described for the first time in Tunisia including 3 variations that have not been reported previously in public databases namely BRCA1_c.915T>A; BRCA2_c.-227-?_7805+? and BRCA2_c.249delG. Early age at onset, family history of ovarian cancer and high tumor grade were significantly associated with BRCA status. BRCA1 carriers were more likely to be triple negative breast cancer compared to BRCA2 carriers. A relatively high frequency of contralateral breast cancer and ovarian cancer occurrence was observed among BRCA carriers and was more frequent in patients carrying BRCA1 mutations.ConclusionOur study provides new insights into breast and ovarian cancer genetic landscape in the under-represented North African populations. The prevalence assessment of novel and recurrent BRCA1/2 pathogenic mutations will enhance the use of personalized treatment and precise screening strategies by both affected and unaffected North African cancer cases.

Project description:Recommendations for rheumatology nursing management of chronic inflammatory arthritis (CIA) from European League Against Rheumatism (EULAR) states that nurses should take part in the monitoring patients' disease and therapy in order to achieve cost savings. The aim of the study was to compare the costs of rheumatology care between a nurse-led rheumatology clinic (NLC), based on person-centred care (PCC), versus a rheumatologist-led clinic (RLC), in monitoring of patients with CIA undergoing biological therapy.Patients with CIA undergoing biological therapy (n = 107) and a Disease Activity Score of 28 ? 3.2 were randomised to follow-up by either NLC or RLC. All patients met the rheumatologist at inclusion and after 12 months. In the intervention one of two annual monitoring visits in an RLC was replaced by a visit to an NLC. The primary outcome was total annual cost of rheumatology care.A total of 97 patients completed the RCT at the 12 month follow-up. Replacing one of the two annual rheumatologist monitoring visits by a nurse-led monitoring visit, resulted in no additional contacts to the rheumatology clinic, but rather a decrease in the use of resources and a reduction of costs. The total annual rheumatology care costs including fixed monitoring, variable monitoring, rehabilitation, specialist consultations, radiography, and pharmacological therapy, generated € 14107.7 per patient in the NLC compared with € 16274.9 in the RCL (p = 0.004), giving a € 2167.2 (13 %) lower annual cost for the NLC.Patients with CIA and low disease activity or in remission undergoing biological therapy can be monitored with a reduced resource use and at a lower annual cost by an NLC, based on PCC with no difference in clinical outcomes. This could free resources for more intensive monitoring of patients early in the disease or patients with high disease activity.The trial is registered as a clinical trial at the ClinicalTrials.gov (NCT01071447). Registration date: October 8, 2009.
