CD8A and neoplasm: By calculating the CT/IM ratio of tumor-infiltrating immune cells (Figure 5D), CD8+ T cells and CD20+ B cells exhibited similar patterns: the peak distribution of the CT/IM ratio was higher in obstructed tumors than in non-obstructed tumors (obstructed vs. non-obstructed: 0.61 vs. 0.49 for CD8 & T1–3; 0.64 vs. 0.45 for CD8 & T4; 0.40 vs. 0.26 for CD20 & T1–3; 0.46 vs. 0.32 for CD20 & T4).
