Table 3 Concordance of risk classification between core needle biopsy samples and surgical specimens

From: Efficacy of an RNA-based multigene assay with core needle biopsy samples for risk evaluation in hormone-positive early breast cancer

  Core needle biopsy sample (n, %) Surgical specimen (n, %) Total Concordance rate (%)
Low risk High risk
All breast cancers Low risk 17 (54.8) 3 (9.7) 20 (64.5) 83.9
High risk 2 (6.5) 9 (29.0) 11 (35.5)
Total 19 (61.3) 12 (38.7) 31 (100.0)
Non-calcified breast cancers Low risk 17 (68.0) 1 (4.0) 18 (72.0) 92.0
High risk 1 (4.0) 6 (24.0) 7 (28.0)
Total 18 (72.0) 7 (28.0) 25 (100.0)
Solitary (Non-multifocal) breast cancers Low risk 17 (70.8) 0 17 (70.8) 95.8
High risk 1 (4.2) 6 (25.0) 7 (29.2)
Total 18 (75.0) 6 (25.0) 24 (100.0)
