PURPOSE: Define the maximum tolerated dose (MTD), tolerability, and efficacy of gemcitabine given concomitantly with radiotherapy in patients with locally advanced pancreatic cancer.
METHODS AND MATERIALS: Patients were required to have locally advanced T1-T3 resectable pancreatic cancer. Gemcitabine, given twice weekly before irradiation as a 30-min infusion, was tested at 3 dose levels: 20, 50, and 100 mg/m(2). The radiation dose was 50.4 Gy (ICRU) in 28 fractions. The targeted irradiation volume included the tumor, edema, and a 1-cm margin.
RESULTS: Twenty-eight of 34 patients was eligible for analysis of the treatment. The median age was 67 years (range 38-82). Six patients had T1, 9 had T2, and 19 had T3 diseases (AJCC). Dose-limiting toxicities were Grade 4, fatigue and nausea; Grade 3, thrombocytopenia, diarrhea, and infection. The MTD established was at the 50-mg/m(2) gemcitabine dose. A total of 21 of 28 patients underwent surgery: 18 had pancreaticoduodenectomy, 2 hadtotal pancreatectomy, and 1 for palliative surgery. At the time of analysis, 13 of 28 (46%) were disease-free. The estimated median survival was 25 months and overall survival rate at 2 years (Kaplan-Meier) was 55%.
CONCLUSION: Gemcitabine 50 mg/m(2) given twice weekly with concomitant irradiation induces acceptable and manageable toxicity and might prolong survival.
