Therapeutic efficacy and safety of S-1-based combination therapy compare with S-1 monotherapy following gemcitabine failure in pancreatic cancer: a meta-analysis

Résumé

S-1 monotherapy is widely used following gemcitabine failure in pancreatic cancer, especially in East Asia. We performed a meta-analysis to determine whether S-1-based combination therapy had better efficacy and safety compared with S-1 monotherapy. We searched Pubmed, Web of Science, ClinicalTrials.gov, and Cochrane CENTRAL and subsequently included five trials with a total of 690 patients. The combined hazard ratio (HR) or risk ratio; the corresponding 95% confidence intervals of progression-free survival, overall survival, and overall response rate; and grade 3-4 adverse events were examined. Five randomized controlled trials were included. Meta-analysis demonstrated S-1-based combination therapy significantly increased progression-free survival (HR = 0.78, 95% confidence interval [CI]: 0.67-0.90, p = 0.0009) and overall response rate (HR = 1.74, 95% CI: 1.20-2.52, p = 0.003). Evidence was insufficient to confirm that S-1-based combined regimens improved overall survival (HR = 0.87, 95% CI: 0.75-1.00, p = 0.05). There was no significant difference in adverse events between the two treatment arms. In conclusion, S-1-based combination therapy improved progression-free survival and overall response rate compared to S-1 monotherapy with acceptable toxicity.
