Whereas, high expression level of IGF-1R could be seen in most types of tumors than normal tissue based on both comparisons, and significant increased expression of IGF-1R could be seen in tumor samples including BRCA, CHOL, COAD, ESCA, GBM, HNSC, LAML, LGG, LIHC, LUAD, LUSC, PAAD, PRAD, SKCM, STAD, TGCT, and THCA based on the integrated database. This evidence concerns the gene IGF1R and neoplasm.
