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

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.

[A Case of Resected Pancreatic Metastasis of Rectal Cancer after Multiple Resections of Metastatic Lesions].

A 71-year-old man underwent low anterior resection for rectal cancer 10 years prior. He underwent resection of liver metastasis once and that of lung metastases multiple times after the primary surgery. Computed tomography revealed a mass measuring 22mm in size in the pancreatic body 10 years after the rectal resection. We inspected it before surgery by performing EUS-FNA. On suspicion of metastasis of rectal cancer or primary pancreatic cancer, we performed distal pancreatectomy. The pancreatic tumor was diagnosed as metastasis of the rectal cancer. There were multiple metastases in the resected specimen that we were unable to indicate at the preoperative inspection. Resectable pancreatic metastasis from colorectal cancer is rare, but some patients with long-term survival have been reported. If a patient is tolerant to pancreatectomy and has no metastasis in other organs, the patient should be considered as a good candidate for pancreatectomy.
