Bevacizumab Therapy Untreated Unresectable Liver Metastases From Colorectal Cancer

LIAONING CANCER HOSPITAL&INSTITUTE

A multi-center, non-random, open study ,to observe efficacy and safety of bevacizumab plus Oxaliplatin based multidrug chemotherapy as conversion therapy for patients with previously untreated unresectable liver metastases from colorectal cancer.

Study Overview

• Status: Unknown
• Conditions: Colorectal Cancer; Liver Metastases
• Intervention / Treatment: Drug: bevacizumab plus chemotherapy

Detailed Description

PRIMARY OBJECTIVES：To assess the objective response rate(ORR)（8 weeks after chemotherapy）

SECONDARY OBJECTIVES：

1. To assess the R0 resection rate of liver metastases（8 weeks after chemotherapy、every three months follow-up 1 time in R0 postoperative 1-2 years、Every six months follow-up 1 time in R0 postoperative 2-5 years）
2. To assess the incidence of adverse events of level 3-4 （Bleeding、Gastrointestinal Perforation、Anastomotic Fistula、Hypertension、Wound Healing Delay）（8 weeks after chemotherapy）
