To determine whether CD47 mRNA level serves as a prognostic factor in human lung cancers, we retrospectively analyzed gene expression data of 317 lung cancer patients including 100 AC (Table S1 in Supplementary Material), 147 SCC (Table S2 in Supplementary Material), and 70 SCLC (Table S3 in Supplementary Material). This evidence concerns the gene CD47 and lung carcinoma.
