The most common treatment for advanced gastric cancer (AGC) is systemic chemotherapy. The standard treatment for advanced gastric cancer differs worldwide. In Japan, two phase III clinical trials demonstrated the noninferiority of S-1 compared with 5-fluorouracil (5-FU) and superiority of cisplatin plus S-1 (CS), compared with S-1, with respect to overall survival (SPIRITS trial). Oxaliplatin (L-OHP) has a favorable toxicity profile compared with cisplatin; hence, a phase III clinical trial (G-SOX trial) demonstrated the progression-free survival (PFS) and overall survival in CS was 5.4 and 13.1 months and those in SOX was 5.5 and 14.1 months, respectively. Serious adverse events were more frequently seen in CS than in SOX. So, SOX is as effective as CS for advanced gastric cancer with favorable safety profile. After the publication of this G-SOX trial, the combination of oral or intravenous 5-FU and various doses of L-OHP have been reported. And FOLFOX6 regimen (FOLFOX: a combination of 1-LV and FU with L-OHP) was approved for the treatment of AGC in Japan in 2017. FOLFOX was promising for patients with severe peritoneal metastasis from AGC, because the FOLFOX regimen does not require hydration and does not include oral agents. This review summarizes the efficacy and safety of doublet combinations of platinum and fluoropyrimidines using L-OHP for advanced gastric cancer.
