Background/Aim: Immune-related adverse events (irAEs) are associated with the efficacy of nivolumab. However, whether the tolerability of second-line chemotherapy is associated with the efficacy of nivolumab monotherapy (third-line chemotherapy) remains unclear. Our study aimed to investigate whether the results of second-line treatment were associated with the efficacy of nivolumab in patients with gastric cancer. Patients and Methods: We enrolled Japanese patients aged ≥20 years with gastric cancer who were treated with nivolumab as a third-line chemotherapy at Fujita Health University Hospital from October 2017 to September 2021. Patients with the evaluations of complete response, partial response, and stable disease after third-line chemotherapy were included in the disease control (DC) group, while others were included in the progressive disease (PD) group. Results: A total of 126 patients were enrolled. The population of patients aged over 65 years in the DC group was significantly higher than that in the PD group. The number of patients continuing second-line chemotherapy for >7 months was significantly higher in the DC than in the PD group. Age over 65 years [odds ratio (OR)=2.67], duration of second-line chemotherapy over 7 months (OR=3.10), and the occurrence of irAEs (OR=3.60) were detected as the factors associated with disease control after nivolumab chemotherapy. Conclusion: The effect and tolerability of second-line chemotherapy, and age over 65 years are the factors associated with DC after nivolumab chemotherapy. The control of tumour inflammatory status might be important for improving treatment outcomes.
