SLC5A1 and neoplasm: Through univariate analysis, it was found that residual tumour status (R1 and R2) was a predictive factor for a shorter OS (HR = 1.683, 95% CI 1.040-2.723, P = 0.034), and high SGLT-1 (SLC5A1) expression (HR = 0.533, 95% CI 0.328-0.866, P = 0.011) was an independent factor for a longer OS (Table 7).
