JAMA NetworkEfficacy and Safety of Intraoperative Hyperthermic Intraperitoneal Chemotherapy for Locally Advanced Colon Cancer: A Phase 3 Randomized Clinical Trial

From November 15, 2015, to March 9, 2021, scientists conducted an open-label, phase 3 randomized clinical trial at 17 Spanish centers to assess the efficacy and safety of intraoperative HIPEC in patients with locally advanced colon cancer. The primary outcome was the 3-year locoregional control (LC) rate, which was defined as the proportion of patients who did not have peritoneal disease recurrence after adjusting for intention to treat. Patients included ranged in age from 18 to 75 years old and had been diagnosed with locally advanced primary colon cancer prior to surgery. They discovered that combining HIPEC with complete surgical resection for locally advanced colon cancer enhanced the 3-year LC rate compared to surgery alone, and they recommend that this strategy be evaluated for patients with locally advanced colorectal cancer.
