Abstract

Background: This study was initially designed to examine whether oxaliplatin-based regimen was superior to cisplatin-based regimen in tumour remission as first-line chemotherapy for advanced gastric cancer (GC).

Methods: Literature in EMBASE, PUBMED, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, American Society of Clinical Oncology (ASCO) and European Society of Medical Oncology (ESMO) was searched. Only phase II or III randomized controlled trials (RCTs) comparing the effectiveness and safety between oxaliplatin-based and cisplatin-based regimens as first-line treatment for advanced GC were selected. Odds ratios (ORs) with 95% confidence intervals (CIs) were reported. The primary endpoints were complete remission rate (CRR), partial remission rate (PRR), objective response rate (ORR), and disease control rate (DCR). The second endpoint was the toxicity response.

Results: 2,140 patients from six phase II or III RCTs were included. Compared to cisplatin-based therapy, subjects who received oxaliplatin-based treatment had significantly higher PRR (OR: 1.25, 95%CI: 1.05-1.48, P=0.01, I²=0%), ORR (OR: 1.21, 95%CI: 1.02-1.44, P=0.03, I²=0%) and DCR (OR: 1.76, 95%CI: 1.31-2.38, P=0.0002, I²=25%), but not CRR (OR: 0.70, 95%CI: 0.37-1.31, P=0.27, I²=0%). In addition, oxaliplatin-based therapy significantly decreased all grades of leukopenia, neutropenia, anemia, febrile neutropenia, nausea, stomatitis, creatinine elevation and thromboembolism, as well as grades 3-4 of leukopenia, neutropenia, anemia and febrile neutropenia than cisplatin-based regimen. However, oxaliplatin-based treatment strikingly increased the risk of thrombocytopenia, sensory neuropathy, diarrhea, fatigue and liver dysfunction.

Conclusions: Oxaliplatin-based regimen is superior to cisplatin-based regimen in tumour remission as first-line chemotherapy for advanced GC, and is associated with less toxicity and better tolerability.
