Unraveling the role of adjuvant chemotherapy in elderly triple-negative breast cancer: Insights from competing risk analysis using SEER data

Adjuvant chemotherapy significantly was associated with OCD, indirectly improving OS, but has limited direct impact on BCSD in elderly Patients with TNBC. Competing risk analysis highlights the importance of individualized treatment strategies. The validated nomogram provides a practical tool for precision medicine. Future research should explore biological mechanisms and validate these findings in multi-regional cohorts.
