To establish an effective therapy for pancreatic cancer, we made a retrospective survey of gemcitabine treatment performed at 20 hospitals in Nagano Prefecture. We analyzed data of 106 patients (64 men and 42 women, median age 66 years (33-83 years old)), half of whom had stage IV disease. Gemcitabine was administered for 3 consecutive weeks with one week rest in 57 patients, biweekly in 30 patients, initially for 3 weeks with 1 week rest and switched to biweekly schedule to 15 patients, and with another regimen to 4 patients. Analysis of the results of gemcitabine treatment between the 3 weeks with 1-week-rest regimen and the biweekly regimen revealed no differences between regimens in growth inhibition and symptom alleviation. However, we found less occurrence of blood toxicity in the biweekly regimen (40%) than in the 3 weeks with 1 week-rest regimen (59%). Median survival time for the biweekly regime was 9.7 months, only slightly longer than that of the 3 weeks with 1-week-rest regimen (8.5 months). The present study showed that a biweekly regimen for gemcitabine administration may be equivalent to the standard regime of 3 weeks with 1-week-rest regimen. Moreover, the biweekly regimen has advantages over the 3 weeks with 1-week rest regimen both economically and in terms of convenience for outpatient treatment. Therefore, the present results should be confirmed in future prospective studies, with the hope of developing a new standard treatment regimen for pancreatic cancer.
