Outcome following surgery for colorectal cancer

There is evidence to suggest that survival following surgery for colorectal cancer is improving. Audits undertaken in a single institution between 1974-1979 and 1991-1994 provide the opportunity to evaluate the extent to which earlier diagnosis and better surgery contribute to the improvement in survival. There was little evidence that patients were presenting at an earlier stage during the latter period. In contrast, more patients had a potentially curative resection. This analysis confirmed that, over this period, there has been a substantial improvement in survival following surgery for colorectal cancer; this improvement was largely due to better surgery rather than earlier presentation.
