To analyze the prevalence and types of BRCA1/2 mutations in Vietnamese patients with breast, ovarian, prostate, and pancreatic cancers using next-generation sequencing.
Approach:
Study Design: Retrospective cohort study conducted in collaboration with Vinmec Healthcare System and several National Oncology Hospitals in Vietnam.
Patient Selection: Patients diagnosed with triple-negative breast cancer, high-grade serous ovarian cancer, prostate cancer, or pancreatic cancer were selected based on NCCN Guidelines.
Sample Collection: Genomic DNA was primarily extracted from peripheral blood samples, with FFPE tumor tissue specimens used when necessary.
Key Findings:
Germline mutations in BRCA1/2 are significant risk factors for hereditary cancers.
BRCA1/2 mutations are implicated in various malignancies beyond breast and ovarian cancers.
There is a lack of comprehensive data on BRCA1/2 mutations in the Vietnamese population.
Interpretation:
The study aims to fill the knowledge gap regarding BRCA1/2 mutations in Vietnamese patients, which is crucial for effective genetic counseling and targeted therapy.
Limitations:
Limited existing data on BRCA1/2 mutations in Vietnam.
Previous studies primarily focused on Western and East Asian populations.
Conclusion:
The study provides insights into the genetic landscape of BRCA1/2 mutations in various cancer types in Vietnam, which may inform personalized oncology care.
