CD38 and neoplasm: Univariate analysis revealed that the tumor size (p=0.042), status of involved lymph nodes (p<0.001), pathological stage (p<0.001) and the proportion of CD38+ CD8+ T cells (p=0.004) were statistically significantly associated with the 3-year survival rate, whereas the other variables were not related to the 3-year overall survival rate (p for all > 0.05) (Table 2).
