Notably, patients with high PDGFR-β expression in both tumor cells and stromal cells had the worst prognosis, while patients with low PDGFR-β expression in both types of cells had the best survival (Supplementary Fig. 5D), indicating the presence of a synergistic effect of PDGFR-β expression on tumor cells and stromal cells for patient survival. Here, PDGFRB is linked to neoplasm.
