title: Diagnostic accuracy of needle-localized open breast biopsy for impalpable breast disease.
abstract: BACKGROUND
  Needle-localized open breast biopsy (NLBB) is considered the gold standard procedure for the diagnosis of impalpable breast disease. In an observational follow-up study the sensitivity and negative predictive value of this procedure was determined in a clinical population with long-term follow-up.
  
  
  METHODS
  Some 199 consecutive patients with a benign histological diagnosis on NLBB were followed for the occurrence of breast cancer, using information from the Dutch National Morbid-Anatomical Record Department. Based on a review of mammograms and histological slides, an expert panel decided whether the carcinomas detected during follow-up were newly developed, or were present already at the time of the NLBB.
  
  
  RESULTS
  After a median follow-up of 60.5 months, seven carcinomas were detected. At panel review, six appeared to have been missed by NLBB. The sensitivity of NLBB was 99 per cent after 2 years of follow-up, but dropped to 96 per cent after 5 years. Similarly, the negative predictive value dropped from 99 per cent after 2 years to 94 per cent after 5 years of follow-up.
  
  
  CONCLUSIONS
  NLBB is an accurate diagnostic procedure for the evaluation of impalpable breast disease. However, with longer follow-up the accuracy becomes lower than generally reported.
