RESUMO
BACKGROUND: Recently, combination S-1 and CDDP chemotherapy is considered as a standard regimen for unresectable or recurrent gastric cancer. Second-line chemotherapy is reportedly important to improve survival, and combination of Irinotecan and Mitomycin C as second-line chemotherapy has proven effective in phase II study of JCOG 0109-DI. PURPOSE: We assessed the efficacy of combination of Irinotecan and Mitomycin C as second-line chemotherapy for unresectable and recurrent gastric cancer. PATIENTS AND METHODS: We treated 12 patients receiving combination of Irinotecan and Mitomycin C as second-line chemotherapy between Nov. 2002 and Apr. 2006. RESULTS: The response rate was 42% including 2 complete response. Progression-free survival was 6.1 months, and time to progression was 5.4 months. Median survival time after the start of second-line chemotherapy was 11.2 months, and after first-line treatment 20.5 months. One-year survival rate was 50%, and 2-year survival rate was 33%. CONCLUSION: In our hospital, combination of Irinotecan and Mitomycin C as second-line chemotherapy prolonged median survival time, and seemed to be an effective regimen.

A 46-year-old man was admitted to our hospital for further evaluation of a hypoechogenic mass in the pancreatic body. He had no history of hypertension, pancreatitis, abdominal trauma, or portal hypertension. He had no abdominal symptoms. A contrast-enhanced CT scan demonstrated a hypodense, round shaped mass. EUS and MRI also showed it to be a pancreatic mass. Because of the tumor size of more than 30mm and the possibility of malignancy, distal pancreatectomy was performed. Microscopic findings showed the mass was the dissection of the proximal splenic artery. The true lumen of the dissecting aneurysm was occluded and the false lumen developed fusiform dilatation. Moreover, microscopic findings revealed the rupture of the false lumen complicated by pseudoaneurysm. We finally diagnosed the lesion simulating a pancreatic tumor as the pseudoaneurysm of the splenic artery.
