SLC5A1 and neoplasm: Factors with P <  0.1 were enrolled in multivariate analysis, which indicated that residual tumour status (R1 and R2) was a predictive factor for a shorter OS (HR = 1.825, 95% CI 1.136-2.931, P = 0.013), and high SGLT-1 (SLC5A1) expression (HR = 0.593, 95% CI 0.362-0.970, P = 0.038) was an independent factor for a longer OS (Table 5).
