This overview delves into the role of RB1 in both health and disease, exploring its association with the tumourigenesis of various cancers and a distinct subset of soft-tissue neoplasms. Additionally, we discuss the application of immunohistochemistry and fluorescence in situ hybridisation to detect RB1 alterations.
