The impact of MYC gene amplification on the clinicopathological features and prognosis of radiation‐associated angiosarcomas of the breast

Abstract excerpt

AIMS: Radiation-associated angiosarcomas (RT-ASs) of the breast are rare tumours with a poor prognosis. MYC gene amplification is considered to be the hallmark of RT-AS, and is sometimes used as a diagnostic tool to distinguish it from other radiation-associated vascular lesions. However, a small subset of RT-ASs lacks MYC amplification, and this may be associated with better outcome. Loss of trimethylation at...
