Fig. 2: Heterogeneity of immune markers in paired primary and metastatic tumors.

A Heterogeneity in the tumor proportion score (TPS) of PD-L1 expression between paired primary tumors (PTs) and metastatic tumors (MTs). B Circos figure shows the increase and decrease in the continuous quantified value of TPS in different sites of metastases. C Circos figure shows the agreements of categorical TPS in MTs. D Heterogeneity in CD8+ cytotoxic T lymphocytes (CTLs) infiltration between paired PTs and MTs. E Circos figure shows the increase and decrease of CTLs infiltrating in MTs. F Heterogeneity in the spatial distance of CTLs and tumor cells (TCs) between paired PTs and MTs. G Schematic diagram illustrates the spatial distribution of the immune-to-tumor cell distances.
