Abnormal p53 staining and p16 loss are observed frequently in uterine leiomyosarcomas, with 100% specificity and 70% sensitivity against IMT, and correlating with genomic alterations. Conversely, IMT shows normal p53 and p16 staining, highlighting the use of these markers in the differential diagnosis of uterine mesenchymal neoplasms.
