Kaplan-Meier curves for overall survival for above (high) or below (low) the median value within treatment type of of tumor infiltrating lymphocyte subset levels according to primary treatment modality. Surgery patient survival illustrated in upper panels and chemoradiation patient survival illustrated in lower panels. Among surgical patients, high levels of CD8 cells were significant for prognosis (log-rank testing) while for chemoradiation patients, high levels of CD4, CD8 and FoxP3 T-cell infiltrates were significant (log-rank testing). Low and high strata were defined separately for surgery and chemoradiation modality cohorts by median cutoff within treatment set.
