- Brief Summary
This prospective, randomized, controlled clinical study aims to evaluate the objective remission rate of FOLFOX hepatic artery infusion chemotherapy (HAI) in combination with systemic irinotecan with or without bevacizumab versus systemic intravenous FOLFOXIRI with or without bevacizumab in initially unresectable RAS-mutated colorectal cancer patients with liver metastases.
- Detailed Description
PRIMARY OBJECTIVES:
The goal of this prospective, randomized, controlled clinical trial is to evaluate the objective remission rate (ORR) of FOLFOX hepatic artery infusion chemotherapy (HAI) in combination with irinotecan with or without bevacizumab systemic intravenous chemotherapy versus systemic intravenous FOLFOXIRI with or without bevacizumab in initially unresectable RAS-mutated colorectal cancer patients with liver metastases.
SECONDARY OBJECTIVES:
To assess and compare the depth of response (DpR), R0 surgical resection rate, No evidence of disease (NED) rate, progression-free survival (PFS), overall survival (OS), recurrence-free survival (RFS) in resectable patients and safety (chemotherapy-related adverse events, catheterization-related adverse events, surgical complications, etc.) between the two intervention groups.
OUTLINE:
Patients in the HAI group receive FOLFOX via hepatic artery infusion chemotherapy plus intravenous irinotecan with or without bevacizumab every 14 days, while patients in the systemic group receive intravenous FOLFOXIRI regimen with or without bevacizumab every 14 days. Patients will receive a maximum of 12 cycles in total (before and after surgery) unless there is disease progression, unacceptable toxicity, or if the patient withdraws from the study.

- All
- Target Recruitment
- 194
Inclusion Criteria
- Histologically confirmed colorectal adenocarcinoma
- Imaging or pathological confirmation of liver metastases
- The multidisciplinary team determined that the liver metastases were unresectable, defined as (i) ≥5 metastases; (ii) inability to perform R0 resection; (iii) insufficient volume of liver expected to remain after resection; (iv) failure to preserve all 3 hepatic veins after resection, failure to ensure that blood flow to and from the liver and bile ducts can be preserved, and failure to preserve 2 adjacent liver segments. If any of the above criteria are met, it can be considered as initially unresectable liver metastases.
