Trial Information



- Compare the disease-free and overall survival rates of patients with colon cancer
treated with laparoscopic-assisted colectomy vs open colectomy.

- Compare the safety of these regimens in terms of early and late morbidity and 30-day
mortality of these patients.

- Compare the differences in costs and cost effectiveness between these treatments in
this patient population.

- Compare the differences in quality of life of patients treated with these regimens.
(closed as of 4/30/99)

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to
participating center, primary surgeon, site of primary tumor (right vs left vs sigmoid), and
American Society of Anesthesiologists disease classification (I and II vs III). Patients are
randomized to one of two treatment arms.

The extent of colon resection is identical for both arms.

- Arm I: 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.

- Arm II: 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.

PROJECTED ACCRUAL: A total of 810 patients will be accrued for this study within 3 years.
