Abstract: |
Percutaneous biopsy, a less invasive and less expensive alternative to surgery for breast diagnosis, has several advantages for women with known or suspected DCIS. Percutaneous biopsy can (1) spare surgery in women with benign lesions, (2) decrease the number of surgeries that are necessary to treat DCIS, (3) enable the diagnosis of multifocal or multicentric disease that warrants mastectomy, and (4) distinguish benign disease from recurrent carcinoma in women who have been treated with breast-conserving surgery. Limitations of percutaneous biopsy in women with DCIS include histological underestimates, failure to obviate surgery in a minority of patients, and epithelial displacement. Steps that can be taken to facilitate the surgical treatment of women with DCIS include wide sampling of calcifications at percutaneous biopsy placement of a localizing clip if the mammographic lesion is removed at percutaneous biopsy and the use of bracketing wires during needle localization for large areas of DCIS that are diagnosed percutaneously.
