[Efficacy of selective continuous transarterial infusion chemotherapy on advanced pancreatic cancer]

Advanced pancreatic cancer is mainly treated by chemotherapy with poor prognosis. This study was designed to evaluate clinical efficacy and application of selective continuous transarterial infusion chemotherapy in treating patients with advanced pancreatic cancer.

Twenty patients with advanced pancreatic cancer were treated by selective continuous transarterial infusion chemotherapy. The interventional treatment was performed with Seldinger technique,12 patients received percutaneous femoral artery cannulization and catheter retention, 8 received percutaneous left subclavian artery port-catheter system implantation. Chemotheraputic drugs were continuously infused when the catheter was selectively placed in turner feeding artery. Nine patients were treated with pirarubicin (THP)/adriamycin (ADM) plus hydroxycamptothecin (HCPT),and 5-fluorouracil (5-FU)/calcium folinate (CF) regimen,and 11 were treated with gemcitabine (GEM) plus carboplatin (CBP),and 5-FU/CF regimen. Treatment regimens were repeated every 4-6 weeks with each cycle of 4 days. Tumor response rate,clinical benefit response (CBR),and survival time were observed.

Objective response rate was 10% with 1 case of complete remission (CR), and 1 case of partial remission (PR), CBR was 70% (14/20), 6-,and 9-month survival rates were 58.8%,and 39.2%. Median survival time for all patients was 8.8 months. No complication related to cannulization was found.

Selective continuous transarterial infusion chemotherapy is safe,and has good efficacy in treating patients with advanced pancreatic cancer, it may prolong survival time of patients.
