Ultrastructural analysis of fine needle aspirates from benign breast lesions.
Thirty six fine needle aspirates from various types of benign breast lesions were examined by electron microscopy and correlated with their cytological appearances. In all cases the parenchyma consisted of clumps of cohesive cells with the ultrastructural features of epithelial cells. In many cases, particularly from fibroadenomas, the parenchyma consisted of single layers of polarised epitheli...
متن کاملComputerized Diagnosis of Breast Fine-Needle Aspirates
The goal of this work is to determine the accuracy of computer-based image analysis in diagnosing breast fine-needle aspirates (FNA). On 192 FNAs, the computerbased diagnostic accuracy was 97.9%. This is consistent with the 97.5% accuracy projected by machine learning methods during the initial training in 1994 with 569 FNAs. One of the attributes of this system is the rendering of a value that...
متن کاملIncreased yield of total RNA from fine-needle aspirates for use in expression microarray analysis.
Fine-needle aspirate samples hold the potential for gaining valuable insight into the molecular details and prognostic indicators for certain types of cancer in a limited volume of relatively pure tumor cells. Although limited, such clinical samples can be used with high efficiency when analyzed in conjunction with gene-dense expression microarrays. For this reason, it is essential to retrieve ...
متن کاملMolecular Markers in Fine Needle Aspirates of the Thyroid
When Policy Topic is covered The use of the Afirma Gene Expression Classifier in fine needle aspirates of the thyroid that are cytologically considered to be indeterminate (follicular lesion of undetermined significance or follicular neoplasm) may be considered medically necessary in patients who have the following characteristics: Thyroid nodules without strong clinical or radiologic finding...
متن کاملAtypia in fine needle aspirates of breast lesions.
BACKGROUND The atypical category is controversial in fine needle aspiration cytology (FNAC) of the breast; most are benign, but a significant number are malignant. To date, no morphological criterion has been found to be consistent in predicting malignancy. AIMS To evaluate specific cytological parameters and assess their usefulness in predicting histological outcome in a cohort of atypical b...
