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 disease progression and a shorter PFS (HR = 2.590, 95% CI 1.644-4.080, P < 0.001), and high SGLT-1 (SLC5A1) expression (HR = 0.534, 95% CI 0.336-0.848, P = 0.007) was an independent factor for a longer PFS (Table 6).
