Task: Answer Verification
Input (English): Question: Is liposarcomatous differentiation in malignant phyllodes tumours unassociated with MDM2 or CDK4 amplification?
Answer: This study examined molecular changes in the well-differentiated liposarcomatous components of MPT. Despite histological similarity to well-differentiated liposarcoma of soft tissues, liposarcomatous differentiation in MPT lacks the molecular phenotype characteristic of extramammary well-differentiated liposarcoma.
Output (English): yes
