Fig. 1. Kaplan–Meier curves of overall survival of triple-negative breast cancer patients treated with anthracycline-based chemotherapy with or without taxanes, according to pathological prognostic stage and TILs.

Pathological Prognostic Stage is assigned stage for patients who have surgical resection as the initial treatment of their cancer before receipt of any systemic or radiation therapy. It is based on clinical information, biomarker data, and findings from surgery and resected tissue. The 5-year estimated overall survival values (5-Yr OS) are provided together with bootstrap confidence intervals.
