Core Tip

Core tip: We performed this meta-analysis to evaluate the efficacy and safety of gemcitabine plus radiotherapy compared with gemcitabine alone for pancreatic cancer (PC). A total of 336 participants from four original studies were included. Gemcitabine plus radiotherapy resulted in comparable survival results to gemcitabine alone. Moreover, concomitant radiotherapy was associated with a significantly higher incidence of severe (grade 3 or greater) toxicities, mainly anemia, leukocytopenia, thrombocytopenia, anorexia, nausea/vomiting, and asthenia/fatigue. Therefore, radiotherapy is not beneficial with gemcitabine-based chemotherapy for PC. Further exploration for better radiotherapy approaches and therapeutic regimens in the treatment of PC is still warranted.
