CD68 and neoplasm: Using the median fluorescence intensity of INHBA within tumor nests as the cutoff, we classified samples into INHBA_high (n = 47) and INHBA_low (n = 46) groups and quantified the fraction of CD68+ macrophages in three concentric peritumoral zones (0–20 μm, 20–30 μm, and 30–50 μm) surrounding individual tumor cells.
