Surgical Outcomes for Breast Cancer Amid Genetic Ambiguity: Insights on BRCA1/2 Pathogenic Variants and Uncertain Significance Variants
To compare clinicopathological characteristics and surgical management patterns between patients with pathogenic BRCA1/2 variants and those with BRCA variants of uncertain significance (VUS), focusing on specific factors influencing bilateral mastectomy decisions.
Key Findings:
A total of 203 patients with BRCA variants or VUS were included in the final analysis.
Patients with pathogenic BRCA variants had distinct clinicopathological features, such as age at diagnosis and tumor characteristics, compared to those with VUS.
Surgical decision-making was influenced by the presence of VUS, despite guidelines advising against management decisions based solely on VUS.
Interpretation:
The study highlights the clinical implications of BRCA variant classification on surgical management decisions, particularly the uncertainty surrounding VUS that may affect patient outcomes, emphasizing the need for clear communication and guidance.
Limitations:
Retrospective design may introduce selection bias, potentially affecting the validity of the findings.
Limited generalizability due to the study being conducted in a single country.
Potential for incomplete data on long-term outcomes.
Conclusion:
Understanding the impact of BRCA variant classification is crucial for improving surgical decision-making in breast cancer patients, especially those with VUS.
