Abstract PURPOSE: Disease recurrence in the abdominal wall from a primary colorectal cancer is a poorly studied and little understood phenomenon that has received renewed attention after the recognition of port site metastases in patients after laparoscopic colorectal resections. The purpose of the present study was to define the clinical, pathologic, and management issues in patients with abdominal wall metastases from colorectal cancer. METHODS: Patients presenting to Memorial Sloan-Kettering Cancer Center with a diagnosis of colorectal cancer were entered into a prospective database beginning in 1986. Review of this database showed that 31 patients presenting with recurrent disease in the abdominal wall were managed surgically at the institution between 1986 and 1998. RESULTS: A total of 31 patients (19 males) with a median age of 67 (range, 45–86) years presented with recurrent disease between 7 and 183 (median, 24) months after primary surgery. Primary tumors were located in the right colon in 17 patients, left colon in 2 patients, sigmoid colon in 7 patients, and rectum in 3 patients. Nineteen percent of primary tumors were perforated, 45 percent were poorly differentiated, 92 percent were transmural (T3 or T4), and 51 percent had lymph node metastases at presentation. Twenty-two patients presented with a symptomatic abdominal wall mass, whereas recurrence in the abdominal wall was found incidentally in 9 patients undergoing laparotomy. Four patients had isolated abdominal wall disease, whereas the remaining 27 were found to have associated intra-abdominal disease. Six patients who were left with residual intra-abdominal cancer after abdominal wall resection had a median survival time of four months. Twenty-five patients underwent a histologically complete resection of recurrence restricted to the abdominal wall alone (n=4; median survival time, 18 months), abdominal wall and in continuity resection of adherent viscera (n=15; median survival time, 12.5 months), or resection of abdominal wall and intra-abdominal recurrence at a distant site (n=6; median survival time, 22 months, although only 1 patient remained alive with disease). The actual two-year and five-year disease-free survival rates were 16 and 3 percent, respectively. CONCLUSION: Abdominal wall metastases are often indicators of recurrent intra-abdominal cancer; however, aggressive resection in patients with disease restricted to the abdominal wall and associated adherent viscera can result in local disease control with little morbidity and no mortality.
