Figure 2 from Compartment-Specific CD8 Infiltration and Disease-Specific Survival in Resected Ampullary Adenocarcinoma

Kaplan–Meier curves show DSS stratified by (<b>A</b>) PD-L1 CPS 0 vs. ≥1; (<b>B</b>) PD-L1 CPS <10 vs. ≥10; (<b>C</b>) dMMR vs. pMMR; (<b>D</b>) intraepithelial CD3⁺ T-cell presence vs. absence; (<b>E</b>) intraepithelial CD8⁺ T-cell presence vs. absence; (<b>F</b>) stromal CD3⁺ T-cell counts categorized as low vs. high; (<b>G</b>) intraepithelial CD3⁺ T-cell counts categorized as low vs. high; (<b>H</b>) stromal CD8⁺ T-cell counts categorized as low vs. high; and (<b>I</b>) intraepithelial CD8⁺ T-cell counts categorized as low vs. high.

High vs. low count categories were defined using the cohort mean for each marker and compartment (CD3: 56 cells in stroma and 11 cells in epithelium; CD8: 27 cells in stroma and 5 cells in epithelium). Numbers at risk are displayed within each panel. <i>P</i> values are from two-sided log-rank tests. Epi, epithelium; Str, stroma.</p>
