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 = 1.765, 95% CI 1.104-2.822, P = 0.018), and high SGLT-1 (SLC5A1) expression (HR = 0.593, 95% CI 0.369-0.953, P = 0.031) was an independent factor for a longer OS (Table 5).
