Post-Recurrence Survival In Triple Negative Breast Cancer.

e13120Background: Prediction of clinical behavior of triple-negative breast cancer (TNBC) is difficult to achieve. Furthermore, it is characterized by a high rate of recurrences and worse outcomes, especially in patients who develop distant metastasis. Given the prognosis of this population, we analyze the pattern of metastasis and outcomes according to the site of metastasis. Methods: In this study, we included 534 triple negative breast cancer patients who developed recurrence. Metastasis was divided into bone, visceral and multiple sites (bone and/or visceral reported at the same date). Relapse-free survival (RFS) and overall survival (OS) rates were calculated by Kaplan-Meier method, while differences between metastasis were assessed by Log Rank test. Results: The median age was 48 years (range: 21-91). A total of 120 (27.4%) patients had obesity, and 49.4% were premenopausal. The majority of patients correspond to stage (S) III (74%) and 9 had bilateral breast cancer. Adjuvant chemotherapy (ACT) was ...
