and 2019, were enrolled in this retrospective study. Clinicopathological data on pathological tumor size, the status of pathological lymph node metastasis, and clinical course were extracted from patients' medical records. Histological slides were reviewed for variables including tumor morphology and hormonal status. Additional clinical data were obtained from electronic medical records. The Kaplan-Meier method was used to determine the association between survival and TILS. Results Our series contained 123 cases of invasive ductal carcinomas. The mean age was 52 years with extremities of 26 and 102 years. TILS were not significantly associated to response to neoadjuvant chemotherapy (p= 0,728), to metastases (p= 0,737), neither to recurrences (p=0,939). Furthermore, TILs were not associated with the overall survival (p=0,928). Conclusions In this series, TILs seem not to be associated with outcomes. We did not find additional benefits for estimating TILs in triple-positive breast cancer.
