[A Case of Colostomy-Free and Long-Term Survival with 5-FU/CDDP for Local Recurrence of Anal Cancer after Chemoradiation Therapy].

ABSTRACT

We report a case of colostomy-free, long-term survival following 5-FU/CDDP for the local recurrence of anal cancer after chemoradiation therapy(CRT). The patient was a 48-year-old woman who was diagnosed with cStage ⅢA anal cancer. She was treated with CRT(5-FU/MMC plus 59 Gy)and achieved a complete response upon treatment completion. A local recurrence was detected on the left-side wall of her rectum after 6 months. We recommended abdominoperineal resection but the patient refused operation. The patient was treated with chemotherapy consisting of 5-FU(1,000mg/m / 2/day)on days 1-5 and CDDP(100mg/m / 2/day)on day 2. Grade 3 peripheral neuropathy appeared following the completion of 5 courses. Therefore, the dose was reduced to 60%. Twenty-five courses of this treatment were continued and chemotherapy was completed. The patient has been alive with no sign of recurrence for 6 years and 8 months from the initial treatment. CRT for anal cancer is becoming a standard therapy but local recurrence is possible. In these cases, abdominoperineal resection is required. Chemotherapy with 5-FU/CDDP in cases of recurrence can be a colostomy-free option.
