Out of these nine cases, the majority (4/9, 44.4%) were various liposarcomas (three dedifferentiated liposarcomas and one myxoid liposarcoma), with the remaining being two cases of undifferentiated pleomorphic sarcoma, one case of fibromyxoid sarcoma, one case of rhabdomyosarcoma, and one case of synovial sarcoma indicating that positive CDK4 expression is more prevalent in various liposarcomas as compared to other sarcomas. Here, CDK4 is linked to liposarcoma.
