Preoperative Systemic Therapy for Colorectal Cancer Peritoneal Metastases

Preoperative Systemic Therapy With FOLFOXIRI Plus Bevacizumab Followed by Cytoreductive Surgery Versus Upfront Cytoreductive Surgery for Resectable Colorectal Peritoneal Metastases: A Randomized Phase 2 Trial

This is an open-label, parallel-group, phase 2 randomized trial which randomizes patients with isolated resectable colorectal cancer peritoneal metastases to receive preoperative systematic therapy followed by CRS+HIPEC and postoperative chemotherapy or upfront CRS+HIPEC followed by postoperative chemotherapy.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Chemotherapy group; 6 cycles of mFOLFOXIRI±Bev is followed by cytoreductive surgery. Postoperative 6 cycles of mFOLFOX is scheduled.	Drug: Preoperative systematic therapy; 6 cycles of mFOLFOXIRI±Bev is administrated before CRS+HIPEC. Irinotecan165mg/m2 IV day 1, oxaliplatin 85mg/m2 IV day 1, leucovorin 400mg/m2 IV day , bevacizumab mg/kg IV day 1, 5-fluorouracil 400mg/m2, continuous infusion over 46-48h. Dose reduction is permitted. Bev will not be administrated in at the last two cycles for minimizing surgery complications.; Procedure: CRS+HIPEC; CRS+HIPEC aims to achieve CC0/CC1 resection. Oxaliplatin or mitomycin C is determined by the treating physician.; Drug: Postoperative chemotherapy; 6 cycles of mFOLFOX+Bev is administrated after CRS+HIPEC. Oxaliplatin 85mg/m2 IV day 1, leucovorin 400mg/m2 IV day , bevacizumab mg/kg IV day 1, 5-fluorouracil 400mg/m2 IV bolus day 1,5-fluorouracil 400mg/m2, continuous infusion over 46-48h. Dose reduction is permitted.; Drug: Postoperative chemotherapy; 12 cycles of mFOLFOX+Bev is administrated after CRS+HIPEC. Oxaliplatin 85mg/m2 IV day 1, leucovorin 400mg/m2 IV day , bevacizumab mg/kg IV day 1, 5-fluorouracil 400mg/m2 IV bolus day 1,5-fluorouracil 400mg/m2, continuous infusion over 46-48h. Dose reduction is permitted.
Active Comparator: Upfront surgery group; Upfront surgery group is followed by 12 cycles of mFOLFOX+Bev	Procedure: CRS+HIPEC; CRS+HIPEC aims to achieve CC0/CC1 resection. Oxaliplatin or mitomycin C is determined by the treating physician.; Drug: Postoperative chemotherapy; 6 cycles of mFOLFOX+Bev is administrated after CRS+HIPEC. Oxaliplatin 85mg/m2 IV day 1, leucovorin 400mg/m2 IV day , bevacizumab mg/kg IV day 1, 5-fluorouracil 400mg/m2 IV bolus day 1,5-fluorouracil 400mg/m2, continuous infusion over 46-48h. Dose reduction is permitted.; Drug: Postoperative chemotherapy; 12 cycles of mFOLFOX+Bev is administrated after CRS+HIPEC. Oxaliplatin 85mg/m2 IV day 1, leucovorin 400mg/m2 IV day , bevacizumab mg/kg IV day 1, 5-fluorouracil 400mg/m2 IV bolus day 1,5-fluorouracil 400mg/m2, continuous infusion over 46-48h. Dose reduction is permitted.

What is the study measuring?

Primary Outcome Measures
