The CD8 concentration from local primary nasopharyngeal cancer specimen has moderate correlation with both EBNA1 oncoprotein (ρ Spearman correlation coefficient of 0.46; p value = 0.026) and LMP1 oncoprotein (ρ Spearman correlation coefficient of 0.47; p value = 0.023) from local primary nasopharyngeal cancer specimen, Fig. 4. The gene discussed is CD8A; the disease is nasopharyngeal carcinoma.
