Diagnostic Efficiency of Touch Imprints Versus Smears
2018年5月4日 更新者:Maria F. Gonzalez、University of Mississippi Medical Center
Diagnostic Efficiency of Needle Core Biopsy Touch Imprints Versus Fine Needle Aspiration Smears at the Time of Rapid on Site Interpretation
Cytopathologists work along with radiologist in the diagnosis of lesions.
Rapid on site interpretation (ROSE) of fine needle aspiration (FNA) smears of radiologically suspicious lesions is a common clinical practice.
In the last years, the investigators have seen trend towards needle core biopsies of radiologically suspicious lesions.
The investigators want to analyze the challenges of rapid on site interpretation of touch imprints (TI) of needle core biopsies (NCB) versus fine needle aspiration smears.
研究概览
详细说明
This is a retrospective study in which the investigators will analyze the quality of the smears and the touch imprints, the cellularity, the cytomorphologic features of the specimens and the presence of adequate material for ancillary studies.
The specimens will be searched through the University of Mississippi Medical Center's Pathology Laboratory information system (Copath), from January 2011 to December 2017.
The retrospective cases (January 2011 up to now) will be retrieved using natural language search of fine needle aspiration and touch imprints.
The slides of those cases will be reviewed and the cytomorphologic features will be described.

All the cytology cases with rapid on site examination (ROSE) of FNA smears and/or touch imprints of needle core biopsies from January 1st/2011 to December 31st/ 2017, will be retrieved using the University of Mississippi Medical Center's Pathology Laboratory information system (Copath).
The investigators will review the cases and get a number of cases with enough diagnostic features (based on the cytomorphologic features of the cells, quality of the smears and touch imprints, and the cellularity) on each case.
