Colorectal Cancer Surgery Types & Factors

Different colorectal cancer sites of origin dictate the type of surgery patients need to undergo during treatment, according to colorectal cancer expert Mark Kozloff, MD. Learn about the different surgery types and how surgeons determine which is best for a particular colon cancer patient.

Mark F. Kozloff, MD: The surgery for colorectal cancer will differ depending upon the origination site of the colorectal cancer.  Cancers of the rectum that are near the anus may need what we call an AP resection meaning that everything is removed including the rectum.  If a cancer is up higher in the rectum, one can do less surgery meaning that one does not need to remove the rectum, but can do what we call a low anterior resection where just part of the colon removed and the rectum is left behind.  There are different ways of doing colorectal cancer, one can do an open type of procedure where there is a larger incision, also now people are favoring less surgical procedures is in which one can do laparoscopic surgery.

In any case of these surgeries, the cancer needs to be removed, if the lymph nodes nearby the cancer need to be removed, and one wants adequate amount of tissue removed.  We actually look at the number of lymph nodes that are removed within the sample of the surgery to determine, if it was an adequate surgery.  People feel that one needs to remove at least 12 or greater lymph nodes to show that it was a good surgical resection.  So, there are ways of checking the quality of the surgery and the surgery does differ depending upon where the cancer originated from
