The recent development of immune checkpoint inhibitors for many types of cancers has prompted us to identify markers that predict patients with clinical benefits. Several trials on nivolumab for the treatment of esophageal squamous cell carcinoma (ESCC) have been performed worldwide, and the identification of markers specific to ESCC is urgently needed. We conducted a clinical trial on nivolumab for advanced ESCC (JapicCTI-No.142422) and investigated markers using peripheral blood collected from 20 patients enrolled in our institute, including 1 with a complete response (CR), 5 with a partial response (PR), 6 with a stable disease (SD), and 8 with a progressive disease (PD) as clinical responses. The expression of surface molecules and cytokine production by T cells were analyzed using flow cytometry, and clinicopathological factors and general blood parameters were examined. Albumin, neutrophils, %Tim3, %OX40, %CD103, %CD45RACD27, and IL-1b after the first cycle of nivolumab treatment, but not at baseline, distinguished CR/PR from SD/PD patients. When markers to distinguish longer survivors with nivolumab therapy were analyzed, changes in these levels between baseline and after the first cycle of nivolumab treatment, but not levels at each period, were indicative, similar to the tumor burden. Among them, elevations in %Tim-3+CD4 had a marked impact on survival rates. In conclusion, dynamic elevations in %Tim-3 in T cells in the early period of nivolumab therapy have potential as a marker for the clinical responses and prognosis of advanced ESCC patients.
