Brief Summary

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.
