SLC5A1 and neoplasm: Through univariate analysis, it was found that residual tumour status (R1 and R2) was a predictive factor for disease progression and a shorter PFS (HR = 2.200, 95% CI 1.399-3.461, P = 0.001), and high SGLT-1 (SLC5A1) expression (HR = 0.510, 95% CI 0.322-0.809, P = 0.004) was an independent factor for a longer PFS (Table 8).
