In this study, except for prostate adenocarcinoma, sarcoma, cutaneous melanoma, thyroid carcinoma, and thymoma, BIRC5 expression was elevated (p < 0.05) in all cancer types, demonstrating that BIRC5 expression is altered across a variety of tumor cohorts and may thus play a general role in the development and spread of cancer. This evidence concerns the gene BIRC5 and sarcoma.
