In an exploratory subset (n = 5), flow cytometry and in vitro killing assays were conducted on GLUT1+ versus GLUT1− CD8+ tumor-infiltrating lymphocytes (TILs).<h4>Results</h4>Tumoral GLUT1 correlated with Ki67 (Spearman's ρ = 0.31, p = 0.003) but was not independently associated with overall survival in the main cohort (multivariable HR 1.183, 95% CI 0.74-1.90; p = 0.485). The gene discussed is SLC2A1; the disease is neoplasm.
