Perioperative Systemic Therapy for Isolated Resectable Colorectal Peritoneal Metastases

Summary

This is a multicentre, open-label, parallel-group, phase II-III, superiority study that randomises patients with isolated resectable colorectal peritoneal metastases in a 1:1 ratio to receive either perioperative systemic therapy and cytoreductive surgery with HIPEC (experimental arm) or upfront cytoreductive surgery with HIPEC alone (control arm).
