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 = 2.723, 95% CI 1.678-4.419, P < 0.001), and high SGLT-1 (SLC5A1) expression (HR = 0.454, 95% CI 0.280-0.737, P = 0.001) was an independent factor for a longer PFS (Table 8). The gene discussed is SLC5A1; the disease is neoplasm.
