Methods We performed a computerized search using combinations of the following keywords chemotherapy gemcitabine trial and pancreatic cancer . Results Thirty-five trials were included in the present analysis with a total of 9 979 patients accrued. The analysis showed that the gemcitabine-based combination therapy was associated with significantly better overall survival OS ORs p progression-free survival PFS ORs p and overall response rate ORR ORs p than gemcitabine monotherapy. Similar results were obtained when the gemcitabine-fluoropyrimidine combination was compared with gemcitabine with the OS ORs p PFS ORs p and ORR ORs p being better in the case of the former. The OS ORs p PFS ORs p and one-year survival ORs p achieved with the gemcitabine-oxaliplatin combination were significantly greater than those achieved with gemcitabine alone. However no survival benefit OS ORs p PFS ORs p was noted when the gemcitabine-cisplatin combination was compared to gemcitabine monotherapy. The combinations of gemcitabine and other cytotoxic agents also afforded disappointing results. Our analysis indicated that the ORR improved when patients were treated with the gemcitabine-camptothecin combination rather than gemcitabine alone ORs p however there were no differences in the OS .
