Recurrent breast cancer: stereotaxic localization for fine-needle aspiration biopsy. Work in progress

Abstract

The efficacy of stereotaxic localization for fine-needle aspiration biopsy in the detection of recurrent cancer manifested as calcifications on mammograms was evaluated in 43 patients that had been treated with local resection and radiation therapy. Six patients had malignant aspirates and one had an atypical aspirate; examination of the surgical specimens revealed all seven of these to be malignant. Thirteen patients underwent surgical biopsies, the results of which were malignant in seven and benign in six. The remaining 30 patients were followed up with mammography. The follow-up mammograms were obtained at 6-month intervals and demonstrated no change in appearance. On the basis of this initial experience, stereotaxic localization for aspiration biopsy offers the potential to accurately distinguish benign from malignant lesions.
