Background/Purpose. The aim of our study was to evaluate the feasibility and the efficacy of cytoreductive surgery (CS) with intraoperative chemo-hyperthermia in the management of advanced stage IVA (T4N0M0) pancreatic cancer. Methods. From August 1995 through March 1996, seven patients with unresectable adenocarcinoma of the pancreas underwent CS, with preoperative chemotherapy (5-fluorouracil [FU] for 96h), plus 45-Gy external beam postoperative irradiation with a 6-MeV linear accelerator (1.8Gy per fraction, 5 days per week). A single session of intraoperative hyperthermia was performed with a waveguide-type applicator operating at 433MHz, and temperature was measured by inserting a flexiguide needle catheter carrying a thermometry probe with three measuring points into the tumor. The tumor region was heated to 43°C-45°C for up to 60min, while 5-FU 500mg was injected simultaneously through the gastroduodenal artery into the splenic artery (intraoperative regional chemotherapy). Results. Postoperative recovery was uneventful for all patients. After the combined treatment, there was a significant decrease in the values of both serum carcinoembryonic antigen (CEA; P = 0.017, Wilcoxon test) and carbohydrate antigen (CA)19-9 (P = 0.016; Wilcoxon test), from 7.6 ± 1.5ng/ml CEA and 869.6 ± 126.9 U/ml CA to 3.5 ± 0.8ng/ml CEA and 104.7 ± 35.4 U/ml CA19-9. Moreover, there was a significant improvement (P = 0.016; Wilcoxon test) in Eastern Cooperative Oncology Group performance status, pain score, and body mass index. The median overall survival was 18.5 (SE, 1.8) months. Conclusions. Our preliminary clinical results suggest the tolerability and the considerable potential advantage of using cytoreductive resection with preoperative chemotherapy, intraoperative chemo-hyperthermia, and external beam postoperative radiotherapy for the management of advanced adenocarcinoma of the pancreas.
