SLC29A1 and neoplasm: The multivariate Cox regression analysis showed that low hENT1 expression in the primary tumor (HR 2.14; 95% CI 1.33–3.49; p = 0.002), positive lymph node (HR 1.97; 95% CI 1.23–3.16; p = 0.005), and poor tumor differentiation (HR 2.58; 95% CI 1.47–4.51; p = 0.001) as independent prognostic factors still retained their negative impact on survival (Table 2).
