Methodology: This is a retrospective and cohort study conducted from January 2000 to December 2015 on patients with metastatic relapse of breast cancer. Results: Out of 178 patients collected, the metastatic relapses were estimated at 49%, occurring in patients with an average age of 53.4 years. The majority of the patients was educated (91.6%) and did not have a high socioeconomic level (88.2%). The initial tumors were mainly at a clinical stage III (47.8%), SBR grade III (47.2%), high index Ki 67 (46.5%), negative RH (79.3%) and HER2 negative (58%). Metastases were unique in general (62.9%), dominated by bone locations (36.6%), with an average age of occurrence of 2.4 years. After the occurrence of these metastases, the cumulative survival rate was 5% at 3 years, and zero to 5 years. Conclusion: Metastatic relapses were common with poor prognosis.展开更多
