Stereotactic and ultrasound core needle breast biopsy performed by surgeons.

BACKGROUND

The authors evaluated outcomes and treatment costs of stereotactic core needle biopsy (SCNB) and ultrasound core needle biopsy (UCNB), and needle localization biopsy (NLB) in managing patients with mammographic abnormalities presenting to the surgeon.

METHODS

Data for all patients with mammographic lesions who underwent SCNB or UCNB since their introduction at this institution were prospectively collected over 17 months. Mean inclusive costs of the three procedures were accumulated and compared.

RESULTS

Stereotactic core needle biopsy was performed for 342 lesions in 319 women, for a malignancy rate of 19%; UCNB was performed for 157 lesions in 144 patients, yielding a malignancy rate of 17%. With a mean follow-up of 13.5 months, 1 patient with in situ carcinoma was diagnosed late. Absolute cost savings for the period studied was $721,963.

CONCLUSIONS

Minimally invasive breast biopsy procedures can safely and reliably be performed by surgeons in clinical practice with increased patient convenience and decreased costs.
