Cytoreductive surgery combined with intraoperative chemo-hyperthermia and postoperative radiotherapy in the management of advanced pancreatic adenocarcinoma: feasibility aspects and efficacy.
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 96 h), plus 45-Gy external beam postoperative irradiation with a 6-MeV linear accelerator (1.8 Gy per fraction, 5 days per week). A single session of intraoperative hyperthermia was performed with a waveguide-type applicator operating at 433 MHz, 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 degrees C-45 degrees C for up to 60 min, while 5-FU 500 mg 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 +/- 1.5 ng/ml CEA and 869.6 +/- 126.9 U/ml CA to 3.5 +/- 0.8 ng/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.[1]References
