Kim et al. analyzed 328 colorectal adenocarcinoma (CRA) samples and identified a low CD47 positive rate of 16.2% (H-score ≥ 50, calculated as 1 × % of weakly, 2 × % of moderately, and 3 × % of strongly stained tumor cells; total range 0–300), with no positive expression in normal mucosa. This evidence concerns the gene CD47 and neoplasm.
