LAT and cancer: Moreover, among luminal B-like type cancer (the aggressive phenotype), high LAT1 expression was an independent poor prognostic factor in univariable (HR = 2.58; 95% CI 1.14–5.86; p = 0.023; Fig. 2b) and multivariable (HR = 3.39; 95% CI 1.35–8.52; p = 0.0094; Supplementary Table 3) analyses.
