OBJECTIVE: Chemoradiotherapy with 5-fluorouracil has been accepted as a standard care for locally advanced pancreatic cancer; however, it has not been shown to be superior to chemotherapy alone in the gemcitabine era. The present multicentre phase II study was conducted to evaluate the efficacy and safety of Gem monotherapy against locally advanced pancreatic cancer in comparison with the historical data of chemoradiotherapy with 5-fluorouracil.
METHODS: Eligibility criteria included patients with histologically proven locally advanced pancreatic cancer, all lesions encompassed by a square of 15 cm on one side, no prior treatment, good performance status and adequate organ function. Gemcitabine was given intravenously at a dose of 1000 mg/m(2) over 30 min on days 1, 8 and 15, repeated every 4 weeks. The primary endpoint was %1-year survival. Expected and threshold %1-year survival were 40 and 25%, respectively.
RESULTS: Between January 2006 and February 2007, 50 locally advanced pancreatic cancer patients were registered. The major grade 3-4 adverse events were neutropaenia (62%), thrombocytopaenia (18%), fatigue (12%) and infection-biliary tree (12%). Haematological toxicity was mostly transient and there was no episode of infection with grade 3-4 neutropaenia. Up to the final follow-up in February 2009, the median overall survival was 15.0 months with a %1-year survival of 64.0%.
CONCLUSIONS: Gemcitabine monotherapy demonstrated far better survival than historical data for chemoradiotherapy with 5-fluorouracil with mild toxicities. Gemcitabine could be consider as a standard treatment for locally advanced pancreatic cancer.
