A core breast biopsy diagnosis of invasive carcinoma allows for definitivesurgical treatment planning

BACKGROUND: We reviewed our image-guided core needle breast biopsy (IGCNBB) experience with patients diagnosed with invasive carcinoma (IC) to determi ne the accuracy of a core biopsy diagnosis of invasion and our ability to p erforin a single definitive cancer operation. METHODS: All IGCNBBs between July 1993 and July 1997 were reviewed to ident ify patients diagnosed with IC. Data included initial surgical treatment, s urgical pathology, and subsequent surgical treatment. RESULTS: Of the 1,676 biopsies, invasive carcinoma was diagnosed in 208 wit h 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 IO is accurate and allows for definitiv e 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. Am J Surg. 1998; 176:497-501.
