Surgery With or Without Combination Chemotherapy in Treating Patients With Liver Metastases From Colorectal Cancer

Colorectal Cancer Clinical Trial

Official title: Pre- and Post-Operative Chemotherapy With Oxaliplatin 5FU/LV Versus Surgery Alone in Resectable Liver Metastases From Colorectal Origin - Phase III Study

Status Active, not recruiting

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and combining chemotherapy with surgery may kill more tumor cells. It is not yet known if surgery is more effective with or without chemotherapy for liver metastases.

PURPOSE: Randomized phase III trial to compare the effectiveness of surgery with or without combination chemotherapy in treating patients who have liver metastases from colorectal cancer.

Clinical Trial Description

OBJECTIVES:

• Compare the progression-free and overall survival of patients with resectable colorectal liver metastases treated with surgery with or without neoadjuvant and adjuvant oxaliplatin, fluorouracil, and leucovorin calcium.

• Compare the percentage of patients with total resection with these two treatments.

OUTLINE: This is a multicenter study. Patients are stratified according to participating center, prior adjuvant chemotherapy (yes vs no), plasma CEA level in ng/mL at diagnosis of liver metastases (5 or less vs 6 to 30 vs 31 or greater), serosa extension of primary cancer (absent T1 or T2 vs present T3 or T4), lymphatic spread of primary cancer (absent vs present N+), time interval between diagnosis of primary tumor to metastases (2 years or more vs fewer than 2 years), and number of metastases (1 to 3 vs 4). Patients are randomized to one of two treatment arms.

• Arm I: Patients receive oxaliplatin IV over 2 hours on day 1 and leucovorin calcium (LV) IV over 2 hours followed by fluorouracil (5-FU) IV over 22 hours on days 1 and 2. Treatment repeats every 15 days for 6 courses in the absence of disease progression or unacceptable toxicity.

At 2 to 5 weeks after chemotherapy, patients undergo liver resection. Patients with progressive disease after 3 courses of chemotherapy undergo liver resection at least 2 weeks after completion of course 3 and do not receive postoperative chemotherapy.

At 2 to 5 weeks after surgery, patients receive oxaliplatin, LV, and 5-FU as in preoperative chemotherapy.

• Arm II: Patients undergo liver resection. Patients are followed every 3 months for 2 years and then every 6 months thereafter.
