Although peritoneal carcinomatosis from breast cancer is a rare event it frequently causes morbidity and mortality. Current literature provides scarce information on its management. We report outcomes in 5 patients (mean age 59.4 years) with peritoneal carcinomatosis from breast cancer treated with maximal cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) by the closed technique, at 40 °C for 1 h with cisplatin 75 mg/m(2). The primary breast cancer was a ductal carcinoma in 3 patients and a lobular carcinoma in 2. Mean peritoneal cancer index was 20.2. In 4 of the 5 patients surgery achieved macroscopic complete cytoreduction. One patient died of disease at 56 months, 4 are alive and disease-free at 13, 45, 74 and 128 months. These encouraging outcomes suggest that cytoreduction and HIPEC is a promising approach to offer to highly selected patients with peritoneal carcinomatosis from breast cancer and that this approach merit investigation in a larger series.
