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 = 2.309, 95% CI 1.486-3.587, P < 0.001), and high SGLT-1 (SLC5A1) expression (HR = 0.547, 95% CI 0.350-0.855, P = 0.008) was an independent factor for a longer PFS (Table 6).
