In conclusion, oncological results for laparoscopic and open surgery of colorectal cancer are similar. The short-term benefits obtained with laparoscopy appear to be minor in terms of medical service delivered. Absence of data makes it impossible to judge the medical service delivered in the longer term.
The main needs identified by the working group were: - establishing a regional cancer registry; - producing a standardised single document for multidisciplinary cancer units;- drawing up standardised trial protocols (learned societies); - cost analysis studies that include quality of life; - specific randomised controlled trials in rectal cancer and right colon cancer, to provide a definitive response regarding technique for these two indications, and specific trials in left colon cancer, to standardise the technique; - an assessment by the colleges of the experience required for performing laparoscopy, of training methods and continuing medical education.
