Abstract:
Case 1 is a 68-year-old woman with locally recurrent rectal cancer(LRRC)developed 5 years after resection of primary rectal cancer. The tumor seized right lateral side in pelvic. We performed tumor excision after preoperative chemoradiation comprised external beam radiation with oral S-1(tegafur/gimeracil/oteracil). He has been relapse-free for 3 years 3months after surgery. Case 2 is a 74-year-old man with LRRC developed 2 years after resection of primary rectal cancer. The tumor was located dorsal to anastomosis site in pelvic. We performed abdominoperineal resection for LRRC after preoperative chemoradiation with oral S-1. He has been relapse-free for 2 years. It was suggested that preoperative radiotherapy combined with oral FU for local recurrence after rectal cancer may contribute to distant and local control.
