Locally advanced breast carcinoma: evaluation of mammography in the prediction of residual disease after induction chemotherapy.

Abstract

The diagnostic value of mammography in the evaluation of tumor response to induction chemotherapy depends primarily on the extent to which the tumor can be delineated from the adjacent breast tissue. For tumors whose margins can be defined by more than 50% on the baseline mammogram, the diagnostic reliability of mammography is high. Ill-defined masses should preferably be assessed with other imaging procedures such as ultrasonography or magnetic resonance imaging.
