Alternate Title

Conventional Surgery Compared With Laparoscopic-Assisted Surgery in Treating Patients With Colorectal Cancer

Basic Trial Information

Objectives

1. Determine whether longitudinal and circumferential resection margins and lymphatic clearances obtained during laparoscopic surgery are different from those obtained with conventional open surgery in patients with colorectal cancer.
2. Compare the patterns of loco-regional or distant metastatic spread after these two surgical methods in these patients.
3. Compare the morbidity and mortality rates in these patients after these two surgical methods, particularly in terms of the technical or thromboembolic complications that may develop as a consequence of prolonged pneumoperitoneum.
4. Compare the disease-free or overall survival of these patients after these two operative procedures.
5. Determine, in those patients in whom laparoscopic surgery fails, which investigatory modalities are appropriate for providing pre-operative indications that a patient is an inappropriate candidate for laparoscopic dissection.
6. Compare the differences in quality of life between the two operative procedures, particularly in patients with advanced disease.

Expected Enrollment

Approximately 1,200 patients will be accrued for this study within 5 years.

Outline

This is a randomized, multicenter study.

Patients undergo laparoscopic surgery or conventional open surgery.

Patients are followed at 1 and 3 months following surgery, then every 3 months for the first year, every 4 months for the second year, and then every 6 months thereafter.
