Revised 16 October 2012
- These guidelines reflect current optimal practice in BC and were developed through consensus of the Provincial GI Tumour Group.
- These guidelines are not a substitute for a consultation with an appropriate specialist.
- These guidelines are current as of September 2012. Every effort will be made to update them to reflect changes in practice.
Definitions: For the purpose of determining the most appropriate adjuvant therapy, the following definitions, while not strictly anatomically correct, are used.
Colon: The colon is the peritonealized portion of large intestine, spanning the cecum to the peritoneal reflection.
Rectum: The rectum is the non-peritonealized portion of the large intestine, extending from the peritoneal reflection to the anal canal. Cancers located at the level of the peritoneal reflection are often treated as per rectal cancers.
Although colon and rectal cancers share many features, there are sufficient differences to justify separate management guidelines. Accordingly, Rectal cancer is dealt with in this section; Colon cancer is reviewed in a preceding section.
