Popis: BACKGROUND Patients with American Joint Committee on Cancer Stage IV advanced pancreatic carcinoma have been treated by systemic chemotherapy, intraarterial chemotherapy, radiation therapy, and multidisciplinary treatment using a combination of these. However, the outcome has not always been satisfactory. In the current study the authors describe the method and results of a new chemotherapy for advanced pancreatic carcinoma. METHODS To restrict the blood flow into the pancreas (mainly to the great pancreatic artery and the caudal pancreatic artery), the peripancreatic blood vessels were embolized superselectively with microcoils. In 31 patients with advanced pancreatic carcinoma, the catheter tip for the arterial infusion chemotherapy was placed in the splenic artery just proximal to the branching of the great pancreatic artery when the treatment was given for primary tumors, and in the common hepatic artery when the treatment was given for a metastatic liver lesion. The other end of the catheter was connected to an implanted injection port embedded in the femoral region, and 5-fluorouracil and cisplatin were administered by continuous arterial infusion. RESULTS Of the 31 patients with advanced pancreatic carcinoma, 23 (74%) underwent hemodynamic change and arterial infusion chemotherapy, with a response rate of 73.9% (complete response rate of 8.7% and a partial response rate of65.2%) and a mean survival period of 18.26 ± 10.06 months. The 1-year, 2-year, and 3-year survival rates were 90.9%, 42.8%, and 18.3%, respectively, with a mean survival period of 19.0 months. Of these 23 patients, the 16 patients with liver metastases had a response rate of 68.8% and a mean survival period of 16.25 ± 8.35 months, whereas the 7 patients without liver metastases had a response rate of 87.5% and a mean survival period of 22.86 ± 12.69 months. CONCLUSIONS In patients with Stage IV advanced pancreatic carcinoma, arterial infusion chemotherapy after hemodynamic change was found to be effective against both primary tumors and metastatic liver lesions. The authors believe that the treatment presented in the current study should be attempted, even in patients with advanced pancreatic carcinoma, as long as the blood vessels for vascular supply distribution exist.
