Radiopathological features predictive of involved margins in ductal carcinoma in situ

摘要

INTRODUCTIONDuctal carcinoma in situ (DCIS) usually manifests as microcalcification on mammography but may be uncalcified. Consequently, a quarter of patients undergoing excision of a presumed pure DCIS require further surgery to re-excise margins. Patients at highest risk of margin involvement may benefit from additional preoperative assessment.
