[Stereotactic excisional nonpalpable breast lesions using the advanced breast biopsy instrumentation].

UNLABELLED

Today, the widespead use of mammography has increased the detection of suspected nonpalpable lesions. Accordingly, the number of surgical biopsies is higher.

PURPOSE

Evaluation of Advanced Breast Biopsy Instrumentation (ABBI) system as a promising alternative to conventional surgical biopsy in stereotactic excisional breast biopsies less than 20 mm.

METHODS

From October 1998 and May 1999, 33 women have had: stereotactic excisional breast biopsies less than 20mm using ABBI. Epidemiologic, mammographic and histologic datas were collected.

RESULTS

Mammographic finding were 23 microcalcifications and 10 nonpalpable solid nodular densities. In 25 cases, pathology were benign (79%), 7 cases (21%) were cancer. In these cases, the cancer could be treated later, with a single surgical procedure. No complication occurred and tolerance was excellent in most cases.

CONCLUSION

Stereotactic excisional breast biopsies less than 20 mm using ABBI is a very good alternative (reliable, reproducible, ambulatory, very weak morbidity) to surgical biopsy.
