title: Improved breast cytology results with near patient FNA diagnosis.
abstract: OBJECTIVE
  To examine the impact of a cytopathologist using near patient fine needle aspiration diagnosis (NPFD) for breast diagnosis.
  
  
  METHODS
  The cytology results of all palpable solid breast lesions undergoing fine needle aspiration (FNA) during a two-year period were prospectively audited and categorized as definitely benign or malignant (definite), probably benign, indeterminate or suspicious (indefinite) or unsatisfactory. The final diagnosis (benign or malignant) was determined from a review of patients' charts and a survey of patients' family physicians. Aspirates were performed by surgical staffand reported either later (non-NPFD) or by NPFD.
  
  
  RESULTS
  Of 720 FNAs, 230 were by NPFD and 490 by non-NPFD. NPFD was associated with a significantly greater proportion of definite reports (91.9% versus 82.4%). NPFD of discrete breast lumps was associated with higher specificity (89.1% versus 67.5%) and a lower unsatisfactory rate (9.4% versus 19.6%) than non-NPFD. NPFD did not improve the unsatisfactory rate of FNAs from diffuse breast thickenings.
  
  
  CONCLUSIONS
  FNA by a dedicated specialist and immediate reporting should be an integral part of a breast diagnostic service.
