Concordance between Core Needle Biopsy and Surgical Excision Specimens for Tumour Hormone Receptor Profiling According to the 2011 St. Gallen Classification, in Clinical Practice
To focus on and compare the tumor hormone receptor profiles on core needle biopsy (CNB) and subsequent surgical excision specimens in a large clinical series of invasive breast carcinoma patients, with regard to guidelines proposed at the St. Gallen International Expert Consensus on the Primary Therapy of Early Breast Cancer 2011. A total of 993 consecutive patients who had hormone receptors (HR) assays performed on both CNB and subsequent surgical excision specimens of invasive carcinomas were included (1,110 tumors). Concordant tumor HR profiles between CNB and surgical excision specimens were noted in 1,085 of 1,110 tumors (97.75%). Among 138 tumors considered negative on CNB (both HR assays
