For each FNA case, all subsequent core needle, incisional or excisional biopsies were recorded as was the result of the definitive operative procedure. In 59 cases, FNA yielded a result insufficient for definitive therapy necessitating surgical biopsy.

The results showed a statistically significant increase (P<0.001) in mean NA and a statistically significant decrease (P<0.001) in mean CA values of tobacco users with leukoplakia as compared to non-users, hence NA/CA ratio value was significantly higher in tobacco users with the lesion.

We expect the computational and visual insights into 3D tissue architecture provided by histotomography to be useful for reference atlases, hypothesis generation, comprehensive organismal screens, and diagnostics. The cytological smear classified in accordance with the Pap classification was compared with the histopathological diagnosis. So careful reading of, Sometimes the material is sub optimal due to m, long before staining). The diagnosis was confirmed by characteristic immunohistochemical stains on pleural fluid material (Papanicolaou stain, ×600). The aim of this study was to assess the ability of Raman spectroscopy to screen for histologically confirmed cases of Cervical Intraepithelial neoplasia (CIN) using biobanked liquid based cytology (LBC) samples. Correlation wi, the clinical and radiological picture is always hel, sputum cytology sometimes are missed due to their, dicult to diagnose by urine cytology. Our study suggests that the combination of ISET®-CTC and ICC-PSA-marker-testing has an estimated positive-predictive-value (PPV) of 99% and a negative-predictive-value (NPV) of 97%, providing a more reliable screening test for prostate cancer than the standard PSA-blood-test (PPV = 25%; NPV = 15.5%). Conversion to core biopsy during FNA is infrequent but justified in most cases. Secondary cancers were detected in 63% (n = 7/11) of men with mixed CTC-population (ICC-PSA-positive/ICC-PSA-negative).

The aim of this study is to demonstrate the effect of tobacco on oral mucosa by cytomorphometric analysis of cells with the help of exfoliative cytology and to find out the improvement in diagnostic sensitivity of exfoliative cytology in the detection of dysplastic changes and early oral malignancy. Specimens are obtained mechanically, by scrapings or needle aspirates, or by collection of exfoliated material from various body fluids.

The panels on the left side are from the FNA material using the CRAT method and the panels on the right are from the same patient after the node was excised surgically. On-site immediate evaluation of FNA specimens can be beneficial in determining the adequacy of the aspirate and in providing accurate preliminary diagnoses of the specimens, thus allowing for rapid clinical decisions. A brief description of the different techniques in performing Fine Needle Aspirations will be presented. In 27 cases (96%), the rationale for conversion was considered to be appropriate, and in 3 of these (11%) the core provided a change in diagnosis. 80.10 MB PDF Free Download Here. the Johns Hopkins Hospital. e, bottom line is to get enough diagnostic cells fro, mass.
