Preoperative gemcitabine and cisplatin followed by gemcitabine-based chemoradiation for resectable adenocarcinoma of the pancreatic head.
PURPOSE: We conducted a phase II trial of preoperative gemcitabine and cisplatin chemotherapy in addition to chemoradiation (Gem-Cis-XRT) and pancreaticoduodenectomy (PD) for patients with stage I/II pancreatic adenocarcinoma. PATIENTS AND METHODS: Chemotherapy consisted of gemcitabine (750 mg/m(2)) and cisplatin (30 mg/m(2)) given every 2 weeks for four doses. Chemoradiation consisted of four weekly infusions of gemcitabine (400 mg/m(2)) combined with radiation therapy (30 Gy in 10 fractions administered over 2 weeks) delivered 5 days per week. Patients underwent restaging 4 to 6 weeks after completion of chemoradiation and, in the absence of disease progression, were taken to surgery. RESULTS: The study enrolled 90 patients; 79 patients (88%) completed chemo-chemoradiation. Sixty-two (78%) of 79 patients were taken to surgery and 52 (66%) of 79 underwent PD. The median overall survival of all 90 patients was 17.4 months. Median survival for the 79 patients who completed chemo-chemoradiation was 18.7 months, with a median survival of 31 months for the 52 patients who underwent PD and 10.5 months for the 27 patients who did not undergo surgical resection of their primary tumor (P < .001). CONCLUSION: Preoperative Gem-Cis-XRT did not improve survival beyond that achieved with preoperative gemcitabine-based chemoradiation (Gem-XRT) alone. The longer preoperative interval required more durable biliary decompression (metal stents) but was not associated with local tumor progression. The gemcitabine-based chemoradiation platform is a reasonable foundation on which to build future phase II multimodality trials for stage I/II pancreatic cancer incorporating emerging systemic therapies.
