What is the diagnostic value of XXXX cytology and galactography in detecting duct pathology?

@entity1 @entity0 @entity5 @entity1185 @entity2286 @entity3389 @entity652
The present study aimed to evaluate the diagnostic value of @entity3389 ( @entity3389 ) cytology and galactography. Ninety-four @entity1 submitted to duct excision, representing a total of 98 duct excisions, were retrospectively analyzed from January 1997 to May 2007. Histology of ducts excised revealed 35% duct ectasia (DE), 31% duct @entity1185 (DP), 20% potential @entity5 (PMTL), 6% @entity0 ( @entity0 ), 1% @entity652 and 6% normal breast tissue. Cytology had a sensibility and specificity in detecting duct pathology of, respectively, 40% and 61.3%, a positive predictive value ( @entity2286 ) of 53.8% and a negative predictive value (NPV) of 47.5%. Concerning malignant and PMTL, cytology had a sensibility and specificity of, respectively, 46.2% and 62.3%, a @entity2286 of 25% and a NPV of 82.5%. @entity0 was never suggested by positive cytology. Galactography had a sensibility and specificity in detecting duct pathology of, respectively, 77.4% and 29.2%, a @entity2286 of 58.5% and a NPV of 50%. For malignant and PMTL, galactography had a sensibility and specificity of, respectively, 80% and 26.7%, a @entity2286 of 19.5% and a NPV of 85.7%. However, galactography never suggested a diagnosis of @entity5 . Cytology and galactography performed together in 49% showed a low Kappa Index (KI < 1), allowing us to conclude that cytology and galactography detect different pathologies. Cytology showed a poor performance in predicting histological diagnosis in face of @entity3389 . Galactography had a good sensibility in excluding malignant lesions and PMTL. Galactography was significantly more sensitive for duct pathology but cytology was more specific for malignant lesions and PMTL.
