Resection of paraaortic lymph node metastasis of colon cancer with graft replacement.

The metastasis sites of colon cancer are the liver, lungs, bones, peritoneum, and lymph nodes. Lymph node recurrences, however, are seldom resected metachronously. We report here a case of en-bloc resection of paraaortic lymph node recurrence together with the invaded abdominal aorta, left kidney and ureter 4 years after curative resection of sigmoid colon cancer. Combined resection of the metastatic lymph nodes and the abdominal aorta would be an even more radical procedure and treatment for cancer because of lymphatic spread around the aorta. The slow growth of the cancer might justify this aggressive resection. This is the first report of resection of late paraaortic lymph node metastasis and simultaneous abdominal aortic graft replacement.
