The presence of a germline BRCA1/2 mutation improves options for tailored risk-reducing strategies and treatment in both breast and ovarian cancer patients and their relatives. Currently, referral for germline BRCA1/2 mutation testing of women with epithelial ovarian cancer (EOC) varies widely, based on different criteria, such as age of onset, family history of breast and/or ovarian cancer and histological type of EOC. The overall probability of a germline BRCA1/2 mutation in women with EOC is above 10%, and a substantial part of the germline BRCA1/2 mutation carriers is missed when applying these criteria for referral. Therefore, we strongly recommend referral of all women with EOC for genetic counselling and DNA analysis.

Pancreatic acinar cell carcinoma (PACC) is a rare pancreatic tumor with a heterogeneous clinical course and, except for radical surgery, limited treatment options. We present a comprehensive study encompassing whole-genome and RNA sequencing of 7 tumor samples from 3 metastatic PACC patients to further delineate its genomic landscape and potential therapeutic implications. Our findings reveal distinct signatures of homologous recombination deficiency (HRD) in patients harboring pathogenic germline BRCA1/2 and FANCL mutations, demonstrating favorable responses to poly (ADP-ribose) polymerase 1 (PARP) inhibitors with prolonged disease-free intervals.

Background: Women with ovarian cancer (OC) and a pathogenic variant in the BRCA1 or BRCA2 genes are at increased risk of developing breast cancer (BC). Evidence for long term outcomes in these patients who undergo bilateral risk reduction mastectomy (RRM) after ovarian cancer is sparse. The aim of this study was to analyse the long-term breast cancer-related outcomes of patients who have been diagnosed with ovarian cancer and found to have BRCA1 or 2 pathogenic variants.

Background: The prevalence of germline pathogenic variants in high hereditary risk breast and/or ovarian cancer patients and unaffected subjects referred for testing is an unmet need in low and middle-income countries.
Aim: To determine the prevalence of germline pathogenic variants in high hereditary risk patients with breast and/or ovarian cancer and unaffected individuals.
Methods: We retrospectively reviewed records of patients and unaffected subjects referred for germline pathogenic variant testing due to high hereditary risk between 2010-2020.

Purpose: We developed the online-based counseling tool iKNOW for women with a pathogenic germline variant in to improve risk understanding and quality of life.
Methods: With a randomized controlled trial, we investigated the efficacy of iKNOW with regard to risk understanding (primary endpoint), quality of life, risk perception, and anxiety (secondary endpoints). Self-report questionnaires were administered to = 217 women with a pathogenic variant in before counseling (T0), immediately after (T1), 4 weeks after (T2), and 6 months after (T3).

Background: There is increasing interest in enhancing the response of the PARP inhibitor olaparib, which is currently approved for pancreatic ductal adenocarcinoma (PDAC) patients with defects in DNA damage repair associated with germline BRCA1/2 mutations. Moreover, agents that can mimic these defects in the absence of germline BRCA1/2 mutations are an area of active research in hopes of increasing the number of patients eligible for treatment with PARP inhibitors. The extent to which regorafenib, an FDA-approved tyrosine kinase inhibitor, can be used to enhance the efficacy of PARP inhibitors in PDAC cells without known BRCA1/2 mutations remains to be investigated.
