BRCA2 positive

While providing survival benefits to previously progressed mCRPC patients presenting deleterious BRCA1/2 gene mutations, PARP inhibitors are not cost-effective and require major price reductions to reach local WTP thresholds.

BRCA positivity was detected in 23.8% of the patients. A statistically significant association was shown between BRCA mutations and patient and family history.

The presence of a DCIS component carries varied prognostic significance in BRCA1 and BRCA2 mutations. A tailored approach may be necessary when determining treatment options for breast cancer patients with BRCA1/2 mutations based on the presence of DCIS.

However, implementing these advanced treatment guidelines in LMICs with complex, fragmented and underfunded healthcare systems presents numerous challenges. In this review, we explore the current status and obstacles associated with managing BRCA1/2-associated breast cancer in LMICs.

HRD positive tumours were specifically of high-grade morphology: HGSC and carcinosarcoma. The correlation of molecular status with histological features is important in order to be able to select the cases in which analysis is required. The majority of HGSCs with SET features are HRD tumours independently of BRCA status.

In conclusion, miR-1273g-3p, and miR-3135b exhibit significant potential as diagnostic markers. However, further research is needed to comprehensively investigate these miRNAs diagnostic and predictive characteristics in a larger cohort.

Almost 70-80% of BRCA2-mutated BC are estrogen receptor (ER)-positive, which is a particular type of ER-positive BC that differs from sporadic ER-positive BC. This article reviews the clinicopathological features, treatment, and prognosis of ER-positive and BRCA2-mutated BC to provide a reference for clinical decision-making.

BRCA1/2 mutations occurred in 6.6% of patients with HER2/neu-positive BC and did not affect survival outcomes. Assessing the potential benefits of new treatment strategies, such as combining anti-HER2/neu therapies with poly(ADP-ribose) polymerase inhibitors, may lead to enhanced outcomes for these patients.

Fifty percent of BRCA1/2 positive women in our study had not undergone annual imaging-based surveillance by mammography or MRI, and none had undergone annual dual screening with mammography and MRI, indicating inadequate breast cancer surveillance in this high-risk group.

PGT-M is a viable option for BRCA-positive patients to avoid transmission while building their families. Most patients in our cohort achieved pregnancy with BRCA-negative euploid embryos.

We encountered a case in which cancer treatment and risk-reducing surgery were performed at the same time for a pathogenic variant carrier who was very anxious about developing cancer. Surveillance of cancer-free BRCA1/2 mutation carriers and expansion of insurance coverage for surgery are important future issues.

BRCA1/2-positive breast cancer with DCIS components is more likely to be hormone receptor-positive and of lower grade compared to patients with IDC only. A tailored approach might be necessary in establishing treatment options for breast cancer patients with BRCA1/2 mutations according to the presence of DCIS.
