Extended operations for extracolic invasion by colon cancer.

Out of 618 cases of colon cancer treated between 1976 and 1986, 25 had an unusual local invasion. They underwent radical surgery with total resection of one or more adjacent organs. This group is made of 17 female and 8 male patients, with an average age of 58 years. All the patients underwent resection of the colon with radical excision of the locally invaded organs. Only one case of postoperative death is recorded. Postoperative surgical complications were rare. This experience confirms that colic resection extended to adjacent organs invaded by the tumor gives a low risk of relapse and satisfying long term results in relatively young patients with good general conditions and without remote metastases.
