ABSTRACT: Background
Despite advances in human epidermal growth factor receptor 2 (HER2)-targeted therapies, HER2-positive early-stage breast cancer (BC) exhibits substantial outcome heterogeneity after breast-conserving surgery (BCS), complicating personalized chemotherapy sequencing. Robust tools integrating clinicopathological variables and treatment response are urgently needed to optimize survival while minimizing overtreatment. This study aimed to develop and validate a novel prognostic tool for this specific patient population.Methods
Using Surveillance, Epidemiology, and End Results (SEER) data [2010-2016; HER2-positive T1-3N0-1 BC patients (n=13,875) treated with BCS and radiotherapy], we developed and validated nomograms predicting overall and cancer-specific survival (CSS)
