We report a resected case of cancer at the ileum of the blind loop. An 81-year-old male underwent an appendectomy for acute appendicitis and an ileotransverse colostomy for postoperative obstruction when he was 14 years old. He underwent radiation therapy for prostate cancer when he was 75 years old. Six years later, enhanced computed tomography revealed a 7 cm mass in the ileum of the blind loop. Colonoscopy showed wall thickening at the ileum of the blind loop, and biopsy revealed an adenocarcinoma. We performed partial resection of the ileum. The patient was discharged 17 days after surgery. Cancer at the ileum of the blind loop after an ileotransverse colostomy has rarely been reported.

The patient was a 65-year-old male, who underwent low anterior resection for rectal cancer. The pathological diagnosis showed mucinous adenocarcinoma, pSS, and pN0. He complained of diarrhea and melena 4 months after the surgery. Abdominal computed tomography and colonofiberscopy showed a local recurrence of rectal cancer. Because the tumor was diagnosed as unresectable, combined chemotherapy of S-1 (100 mg/day, per os, 4 weeks of treatment and 2 weeks of rest) and PSK (3 g/day, per os, the same schedule as S-1) was started. After the 2 courses of chemotherapy, computed tomography and colonofiberscopy showed a complete disappearance of the tumor. The chemotherapy was continued until the 9th course and then stopped. Five years and 4 months since the induction of a complete response, the patient is still alive without disease recurrence. Combined chemotherapy of S-1 and PSK may be one of useful choices for recurrent colorectal cancer.

The patient was a 75-year-old woman who had undergone resection of a transverse colon cancer two years before. She had anemia and intestinal obstruction, and a diagnosis of multiple metastases to the small intestine was made by double balloon enteroscopy. Eleven metastatic foci were resected by partial resection of the jejunum and ileum. Adjuvant FOLFOX chemotherapy was given, achieving a 26-month disease-free survival. The double balloon enteroscopy was useful in the definitive diagnosis of this case, and aggressive resection with adjuvant chemotherapy contributed to the good outcome.

A 52-year-old man undergoing distal gastrectomy for gastric cancer in July 1998 was found to have a 0-IIa type gastric tumor near EC junction in January 2005. Histological examination showed the tumor was moderately differentiated adenocarcinoma. As the tumor was diagnosed as mucosal cancer, endoscopic mucosal dissection was performed. But pathological findings showed the depth of cancer cell invasion into deep submucosal layer. Then total resection of remnant stomach was performed. Both tumors were diagnosed as EBV-associated carcinoma. It is speculated that the mucosa changing after initial operation would give risk to a new occurrence of EBV-associated remnant gastric carcinoma. And then follow up after operation is important. Although some cases of EBV-associated remnant gastric carcinoma is found for short period after the primary surgery, our case second primary cancer was found 7 year after primary surgery. Long term follow-up by Endoscopy seems to be important.
