Is concomitant radiotherapy necessary with gemcitabine-based chemotherapy in pancreatic cancer?

Abstract:

AIM:To evaluate the efficacy and safety of gemcitabine (GEM) plus radiotherapy compared with GEM alone for pancreatic cancer (PC). METHODS:A systematic search for eligible studies comparing gemcitabine plus radiotherapy with gemcitabine alone for PC was performed using MEDLINE, EMBASE, and the Cochrane Library. A quality assessment was performed in each study. Meta-analyses were performed to study the pooled effects of relative risk with 95% confidence interval (CI). RESULTS:A total of 336 participants from four original studies were included. Gemcitabine plus radiotherapy resulted in comparable overall survival (HR = 0.84, 95%CI: 0.53-1.34, P = 0.48) and progress free survival (HR = 0.99, 95%CI: 0.97-1.01, P = 0.36) 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. CONCLUSION:Radiotherapy is not beneficial with gemcitabine-based chemotherapy for PC. Further exploration for better radiotherapy approaches and therapeutic regimens for the treatment of PC is warranted.
