476Background: Gemcitabine-based chemotherapy is considered as a standard front-line treatment for patients with advanced pancreatic cancer. Although addition of erlotinib or S-1 to gemcitabine has yielded better outcomes, it has showed just modest improvement in survival. To overcome this limitation, we evaluated the efficacy and safety of the combination of gemcitabine, erlotinib, and S-1 for the treatment of advanced pancreatic cancer. Methods: Chemotherapy-naive patients with pathologically proven locally advanced, recurrent or metastatic pancreatic adenocarcinoma were assessed for eligibility. Gemcitabine at 1,000 mg/m2 was administered intravenously on day 1, and 8, erlotinib at 100 mg/day was administered on day 1-21, and S-1 at 60 mg/m2 was administered on days 1-14 every 21 days and continued to maximum of 8 cycles of treatment. Dose escalation of S-1 to 80 mg/m2 was permitted from second cycle for pre-defined tolerable patients. Results: Thirty-seven patients (median age 61.5 years) were enrolle...
