    The Medicare population makes up a large proportion of the patients who undergo evaluation and treatment of mammographically detected breast lesions.

    In the past, the standard approach for obtaining a histological specimen for definitive diagnosis has been wire localization followed by open surgical excision (WL-OSE).

    In recent years, however, imaging-guided large core needle biopsy (LCNB) has been investigated as a more cost effective and less invasive alternative.


    The authors examined accuracy and reimbursement of ultrasound-guided LCNB, stereotactic-guided LCNB, and WL-OSE in 139 Medicare patients who demonstrated abnormalities on screening mammograms in 1994 and 1995.


    Ultrasound-guided LCNB was used to diagnose 20% of these cases, sterotactic LCNB was used to diagnose 68% of the cases, and the remaining 12% were diagnosed using WL-OSE.

    Histological diagnoses for 54 LCNBs (20 ultrasound-guided and 34 stereotactic-guided) were 98% accurate when compared with a subsequent surgical excision specimen.

    Ultrasound-guided LCNB was the most cost-effective approach, showing an average savings of $1,960 per procedure over WL-OSE and $211 over stereotactic-guided LCNB.

    Stereotactic-guided LCNB was significantly more cost effective than WL-OSE, showing an average savings of $1,750 per procedure. (...)
