ABSTRACT
BACKGROUND:
The immune system is affected by the circadian rhythm. The objective of this study was to clarify whether time-of-day patterns (early or late in the daytime) of the infusion of nivolumab and whether its duration affect treatment efficacy in metastatic or recurrent esophageal squamous cell carcinoma (R/M-ESCC).METHODS:
The data of 62 consecutive patients with R/M-ESCC treated with nivolumab between February 2017 and May 2022 were retrospectively reviewed. The infusion of nivolumab before 1300 was set as 'early in the day', and that after 1300 was set as 'late in the day'. The treatment efficacy was compared between early and late groups by 3 criteria (first infusion, during the first 3 months, and all treatment courses).RESULTS:
The overall survival, progression-free survival, and response rate of patients received the first dose in the early group were significantly superior to those of patients in the late group. The progression-free survival and response rate of patients who received the majority of nivolumab infusions before 1300 during the first 3 months were significantly superior to those who received it after 1300, with the exception of overall survival. There were no significant differences in the overall survival, progression-free survival, and response rate between patients who received the majority of nivolumab infusions before 1300 of all treatment courses and those who received it after 1300.CONCLUSION:
The timing of the infusion of nivolumab may affect treatment efficacy in R/M-ESCC.Key words
