A new regional arterial infusion chemotherapy for patients with advanced pancreatic cancer

摘要

Various arterial infusion chemotherapies have been tried for the purpose of local control of advanced pancreatic carcinoma. However, these treatments were not effective against the primary lesion because of its special anatomical position and the complex hemodynamics, although they were effective against the liver metastases. Therefore, the vascular supply distribution was altered by superselective embolization to control the primary legion in the pancreas, after transcatheter peripancreatic arterial embolization toward the primary site. Furthermore, bilateral (hepatic and splenic) arterial infusion chemotherapy was applied to both the primary site and liver metastasis. As a result, the response rate was 73.9%, with a mean survival period 18.26 +/- 10.06 months. We believe that the current chemotherapy was an effective treatment for unresectable pancreatic cancer since it was possible to treat patients with little harm to their quality of life.
