Casting-type calcifications with invasion and high-grade ductal carcinoma in situ: a more aggressive disease?

Hypothesis: Women with breast cancer who have casting-type microcalcifications associated with multifocal invasion and extensive ductal carcinoma in situ (DCIS) form a subset of patients with a poor prognosis. Our study aims to identify the mammographic and pathologic features of this group.

Design: Women with casting-type microcalcifications, multifocal invasion, and extensive DCIS were identified from our tumor board registry.
