NT5E and neoplasm: In the multivariable model a low CD73 expression in tumor cells was significantly correlated with a reduced risk of progression (HR: 0.47; 95% CI: [0.28, 0.8], p = 0.004), whereas a low CD73 expression in surrounding stroma cells showed an increased risk of progression (HR: 4.26; 95% CI: [1.43, 12.7], p = 0.003).
