COLOR trial is a randomized, international, multi center study comparing the outcomes of laparoscopic and conventional resection of colon carcinoma with curative intent. Clinical and operative data will be collected centrally in the coordinating centre in Rotterdam, The Netherlands. Quality of life and costs will be assessed on a national basis.

Primary Outcome Measures:
  • Primary endpoint is cancer free survival at three years.

Secondary Outcome Measures:
  • Secondary endpoints are overall survival at three and five years, 28 day mortality and morbidity, quality of life, costs, location and rates of recurrences and pathologic anatomic characteristics of the resected specimen.

Estimated Enrollment: 1200
Study Start Date: March 1997
Estimated Study Completion Date: March 2008
Detailed Description:

The design involves allocation of all suitable consecutive patients with colon carcinoma to either of the two procedures at a randomization ratio of 1:1. The trial will be stratified according to participating centre, resection type and gender.

Disease free survival for all TNM stages after 3 years is currently about 70%. To detect a difference of 7% in disease free survival rate after 3 years between open and laparoscopic resection of colon cancer, 1200 patients will have to be included (60 vs 67%, two-sided analysis; alfa=0.05, beta=0.20, power=80% and p=0.05). All analyses will be performed on an intention to treat basis.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
