A core breast biopsy diagnosis of invasive carcinoma allows for definitive surgical treatment planning.

BACKGROUND We reviewed our image-guided core needle breast biopsy (IGCNBB) experience with patients diagnosed with invasive carcinoma (IC) to determine the accuracy of a core biopsy diagnosis of invasion and our ability to perform a single definitive cancer operation. METHODS All IGCNBBs between July 1993 and July 1997 were reviewed to identify patients diagnosed with IC. Data included initial surgical treatment, surgical pathology, and subsequent surgical treatment. RESULTS Of the 1,676 biopsies, invasive carcinoma was diagnosed in 208 with follow-up in 204 cases. Invasive carcinoma diagnosis was confirmed in 202 of 204 cases (99%). One hundred ninety-two patients had surgical treatment. Of these 192 patients, 173 (90%) could have achieved definitive surgical treatment with a single operation. CONCLUSIONS An IGCNBB diagnosis of IC is accurate and allows for definitive breast cancer therapy. The potential impact on patient management is that a single operation can usually accomplish what traditionally has required at least two surgical procedures.
