Abstract: Objective  To investigate the prognostic effect of CD38 in patients with esophageal squamous cell carcinoma patients (ESCC). Methods  A retrospective cohort study with 142 ESCC patients was performed. The clinicopathological features and expression of CD38, CD4, CD8, Ki-67, programmed cell death ligand 1(PD-L1) and programmed cell death 1(PD-1) in tumor and immune cells were evaluated. Results  Among ESCC patients with lymph node metastasis, the expression of CD38 had a significant association with the overall survival (P=0.037). The median overall survival was 14 months and 38 months among patients with low and high expression of CD38, respectively. The crude and adjusted hazard ratio of high CD38 expression was 0.46 (95%CI: 0.21-0.98) and 0.32 (95%CI: 0.13-0.76) respectively. The expression of CD38 had a negative correlation with PD-L1 expressed in tumor cells. Conclusion  The high expression of CD38 was associated with a better survival for ESCC with lymph node metastasis.
