RESUMO
We investigated the gastric and esophageal cancer cases treated with immune checkpoint inhibitors and chemotherapy at our hospital. Out of 17 gastric cancer cases, 9 were treated with nivolumab(Nivo)plus S-1/oxaliplatin(SOX), 5 with Nivo plus 5-fluorouracil/Leucovorin/oxaliplatin(FOLFOX), and 3 with Nivo plus capecitabine/oxaliplatin(CapeOX), yielding a response rate of 35.3%. We also treated 3 cases of esophageal cancer. Two of these were treated with Nivo plus cisplatin/5- fluorouracil(CF)and 1 case with pembrolizumab(Pembro)plus CF, with a response rate of 33.3%. The incidence of Grade 3 or higher adverse events was 29.4% in gastric cancer and 33.3% in esophageal cancer, and no serious immune-related adverse events were observed. Further case accumulation and long-term studies are required to evaluate efficacy and adverse events in clinical practice.
