Tumor recurrence in the abdominal wall scar tissue after large-bowel cancer surgery.

In the Melbourne (Monash) series reviewed here the development of apparently isolated incisional scar tissue recurrences after curative excisions for large-bowel cancer proved unusual. Eleven patients with such a recurrence all died of disseminated disease within four years, and most within 12 months, of its development. This suggests that an incisional recurrence is a manifestation of disseminated cancer rather than isolated implantation.
