Efficacy of Neo-Adjuvant Chemoradiotherapy for Resectable Pancreatic Adenocarcinoma: A PRISMA-Compliant Meta-Analysis and Systematic Review. Issue 15 (April 2016) - Liu, Wei
Abstract : Abstract: We have conducted a meta-analysis and systematic review to determine the overall survival, mortality rate, and complete resection rate of neo-adjuvant chemoradiotherapy (CRT) compared with pancreaticoduodenectomy alone in patients with pancreatic adenocarcinoma. Whether neo-adjuvant CRT is beneficial in the treatment of resectable pancreatic cancer or not, it is still a controversial issue. Medline and Cochrane were searched with relevant terms. Eight studies with a total of 833 participants were selected. The meta-analysis was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The analysis revealed neo-adjuvant group may have a benefit in the overall survival, as compared with the resection group, although it did not reach statistical significance (pooled hazard ratio = 0.87, 95% confidence interval [CI] = 0.75–1.00, P = 0.051). We found no difference in the in-hospital mortality rate (pooled odds ratio [OR] = 1.27, 95% CI = 0.35–4.58, P = 0.710). The complete resection rate was significantly higher in the neo-adjuvant group than in the resection group (pooled OR = 2.39, 95% CI = 1.21–4.74, P = 0.012). This meta-analysis found that there was no significant difference in the overall survival between patients treated with neo-adjuvant CRT or pancreaticduodenectomy.
