Summary
Brief summary (as posted)
RATIONALE: Less invasive types of surgery may help reduce the number of side effects and improve recovery. It is not yet known which type of surgery is more effective for colon cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of laparoscopic-assisted colectomy with open colectomy in treating patients who have colon cancer.

Arms and outcomes
Arms (2)
- type
- EXPERIMENTAL
- label
- Conventional surgery
- description
- Patients undergo open laparotomy and colectomy. A standard incision is made through the abdominal wall and the abdominal cavity is explored. A right or left colectomy or a sigmoid resection is performed. Patients may be entered on adjuvant chemotherapy trials after surgery provided the subsequent trial does not include radiotherapy and allows entry of patients from both arms. Quality of life is assessed at baseline and on days 2 and 14 after surgery, at 2 months, and then at 18 months. (closed as of 4/30/99) Patients are followed every 3 months for 1 year, every 6 months for 4 years, and then annually for 3 years.

- label
- Laparoscopic-assisted colectomy
- description
- Patients undergo a laparoscopic-assisted colectomy. A small infraumbilical incision is made through the abdominal skin and the abdominal cavity is insufflated with CO2 to allow access and visualization. The abdominal cavity is explored. If advanced local disease is identified, a celiotomy and colectomy are performed. Otherwise, a right or left colectomy or sigmoid resection is performed using laparoscopic-assisted techniques. Patients may be entered on adjuvant chemotherapy trials after surgery provided the subsequent trial does not include radiotherapy and allows entry of patients from both arms. Quality of life is assessed at baseline and on days 2 and 14 after surgery, at 2 months, and then at 18 months. (closed as of 4/30/99) Patients are followed every 3 months for 1 year, every 6 months for 4 years, and then annually for 3 years.

* Right colon from the ileocecal valve up to and including the hepatic flexure
* Left colon from the splenic flexure to the junction of the sigmoid and descending colon
* Sigmoid colon between the descending colon and the rectum (at least 15 cm from the dentate)
* Diagnosis based on physical exam plus either a proctosigmoidoscopy and barium enema or a colonoscopy

* No transverse colon cancer (i.e., between distal hepatic flexure and proximal splenic flexure)
* No stage IV disease
* No rectal cancer (i.e., below the peritoneal reflection, lower edge of tumor less than 15 cm from dentate)
* No American Society of Anesthesiologists IV/V disease classification
* No associated gastrointestinal diseases (i.e., Crohn's, chronic ulcerative colitis, or familial polyposis) that require additional extensive operative evaluation or intervention
PATIENT CHARACTERISTICS:
Age:
