PURPOSE: Hyperthermia is a mechanistically plausible partner with chemotherapy, although many of the underlying molecular mechanisms of this combination treatment are not yet properly understood. Preclinical studies suggest that there is potential synergy with gemcitabine and that provides the basis for retrospective analysis of a clinical series combining these treatment modalities for patients with advanced pancreatic cancer. PATIENTS AND METHODS: Twenty-nine chemotherapy-naive patients with locally advanced or metastatic pancreatic carcinoma with malignant ascites were treated with intraperitoneal cisplatin 30 mg/m2 and gemcitabine 800 to 1,000 mg/m2 intravenously on days 1, 8, and 15 every 28 days until tumor progression. Patients also received regional hyperthermia treatment (41 to 42°C) on the upper abdomen two times per week from days 1 to 21. RESULTS: In all, 83 cycles of chemotherapy were administered and were generally well tolerated. No patients had a complete response, 13 had a partial response, seven had stable disease, and 9 had progressive disease. Mean progression-free survival and overall survival were 119 ± 61days and 195 ± 98 days, respectively. CONCLUSION: This study provides preliminary evidence that the treatment approach of combined systemic and intraperitoneal chemotherapy plus hyperthermia is well tolerated, is active, and has an acceptable survival profile for patients with stage IV pancreatic cancer and ascites.
