Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Metastasis from Breast Cancer: A Preliminary Report on 4 Cases

Background: Breast cancer (BC) has been ranked as the first malignancy most common and the fifth in mortality rate among women in China. Peritoneal metastases from BC is a rare disease and no guideline or international consensus for it. Objective: To summarise our experiences in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) to treat breast cancer peritoneal carcinomatosis (BC PC). Methods: : 4 BC PC patients underwent CRS+HIPEC were enrolled in this study. The clinic-pathologic characteristics and overall survival (OS) were collected and analysed. Result: The average age at CRS+HIPEC was 59.8 years. The average time of CRS+HIPEC was 8.8 h. The median number of resected organ areas was 7. Overall survival from CRS+HIPEC were 31, 28, 16 and 52 months. There were no serious adverse events (SAEs) during the perioperative period. Conclusions: : The 4 cases provided evidence that integrated therapy with CRS+HIPEC may be a promising strategy to improve the outcome for BC PC patients.
