Diagnosis and operation for locally recurrent rectal cancer.
Local recurrence of rectal cancer following abdominoperineal resection is rarely amenable to limited resection. Six patients with deeply invading recurrent lesions had pelvic exenteration combined with sacral resection. This procedure seems a reasonable treatment for palliation and the chance of cure in selected patients. In order to select good candidates for this extensive procedure, carcinoembryonic antigen (CEA) assays and the diagnosis of locally recurrent tumor with pelvic computed tomography (CT) were evaluated. CEA assay is valuable for diagnosing most recurrent rectal cancers, but it is inadequate for early detection. A high CEA level often indicates extrapelvic tumor spread. CT examination is very valuable for the early detection and localization of recurrence in relation to pelvic structures.
