Olaparib as maintenance therapy in patients with BRCA 1-2 mutated recurrent platinum sensitive ovarian cancer: Real world data and post progression outcome.
A simultaneous detection of germline and somatic mutations in ovarian cancer (OC) using tumor materials is considered to be cost-effective for <i>BRCA1/2</i> testing.
In the present study, 21 BRCA1 and BRCA2 pathogenic variants were detected in 30 patients and BRCA1/2 mutations were significantly associated with a family history of breast/ovarian cancer.
Analyses performed under logistic model, linear mixed model, and model incorporating correlations identified nine significant associations with three gynecologic diseases including four novel findings (rs79219469:C > T, LINC02183, P = 3.3 × 10<sup>-8</sup> and rs567534295:C > T, BRCA1, P = 3.1 × 10<sup>-8</sup> with OC, rs150806792:C > T, INS-IGF2, P = 4.9 × 10<sup>-8</sup> and rs140991990:A > G, SOX9, P = 3.3 × 10<sup>-8</sup> with UCC).
This consensus guide represents a collection of technical recommendations to address the detection of BRCA1/2 mutations in the molecular diagnostic testing strategy for OC.
Germline BRCA 1/2 mutations are associated with a higher hematologic toxicity in patients with ovarian cancer who underwent platinum-based chemotherapy.
NGS-based multiple gene panel resequencing in combination with a high resolution CGH-array was used to identify genetic risk factors for hereditary breast and/or ovarian cancer in 237 high risk patients who were previously tested negative for pathogenic BRCA1/2 variants.
Surveillance of patients with mutations in BRCA 1/2 is done by yearly mammography and breast MRI and by transvaginal ultrasonography and serum CA-125 levels every 6-12 months for ovarian cancer.
Since more than two decades Risk-reducing salpingo-oophorectomy (RRSO) is recommended and widely accepted by BRCA1/2 carriers as a method reducing ovarian cancer risk and improving survival rate.
Women who carry a pathogenic mutation in either a BRCA1 DNA repair associated or BRCA2 DNA repair associated (BRCA1 or BRCA2) gene have a high lifetime risk of developing breast and tubo-ovarian cancer.
MR estimates were calculated using inverse-variance weighted methods from 1044 cases and 1172 controls in a Chinese genome-wide association study and validated by the Ovarian Cancer Association Consortium and Consortium of Investigators of Modifiers of BRCA1/2 studies with 29 396 cases and 68 502 controls of European ancestry.
Testing for variation in BRCA1 and BRCA2 (commonly referred to as BRCA1/2), has emerged as a standard clinical practice and is helping countless women better understand and manage their heritable risk of breast and ovarian cancer.
Carriers of mutations of breast cancer gene 1 and/or 2 (BRCA1/2) have a higher risk of developing breast and ovarian cancers at a relatively young age.
