[A case of advanced pancreas cancer successfully treated by using combined modality therapy].

A 62-year-old woman visited a nearby hospital with chief complaints of diarrhea and weight loss.A computed tomography (CT)scan showed a hypovascular tumor approximately 2 cm in diameter in the pancreatic uncus, and the patient was referred to our department for thorough examination and treatment.The patient was diagnosed with cT4 (A) N0M0, cStage IV a cancer of the pancreatic uncus.The treatment consisted of 3 weeks of gemcitabine and 1 week of drug withdrawal; after completion of 4 courses, concomitant administration of S-1 (ie GS therapy) was initiated.The tumor gradually shrank, and it was not observed on a CT scan 1 year and 8 months later.Although no obvious distant metastasis was observed, a low density area around the superior mesenteric artery still remained.Possibility of viable tumor could not be completely ruled out; therefore, a pancreaticoduodenectomy was scheduled.However, because sclerosis around the superior mesenteric artery was quite severe, bled easily, and was difficult to separate, we decided that excision was impossible and resumed the GS therapy. The primary lung cancer that developed subsequently was resected, and the GS therapy was continued.The tumor in the pancreatic uncus was resected after growth was observed 3 years and 9 months after the initiation of chemotherapy.The patient is currently receiving chemotherapy as an outpatient.

[A case of long-term survival after peritoneal recurrence of rectal cancer achieved by tumorectomy and adjuvant chemotherapy].

The patient was a 40-year-old woman.She began experiencing abdominal pain and constipation in July 2005.S he underwent endoscopy in August, which revealed rectal cancer.She was referred to our hospital for surgery and underwent anterior resection with lymph node dissection in September. The pathological diagnosis was tub2, SS, N2, ly1, v1, stage III b. After discharge, she began oral chemotherapy. However, in April 2006, computed tomography (CT) revealed recurrence in the Douglas pouch. She began FOLFOX4 treatment in May.On follow-up CT performed in July, the recurrent sites were limited to 2 nodules and were deemed resectable. The patient underwent peritoneal dissemination resection, and the pathological diagnosis was metastatic tumor.She subsequently received 11 postoperative FOLFOX4 courses. The chemotherapy regimen was changed to the de Gramont regimen because of peripheral neuropathy. After 56 courses of the de Gramont regimen, the chemotherapy regimen was further changed to UFT/UZEL. The patient received 28 additional courses but experienced hair loss and requested treatment cessation. To date, she remains alive without recurrence.
