cytologic screening

cy·to·log·ic screen·ing

a screening for the detection of early disease, usually cancer, through microscopic examination of a cellular specimen by inspecting each cell and structure present, usually at ×100 magnification with a mechanical stage, so that all areas are screened; the findings are evaluated and significant abnormalities are flagged (for example, by dotting the cover slip) for further evaluation by a cytopathologist. This screening is usually performed by a cytotechnologist, but at times is done by automated machine prescreening.

Data from large randomized trials suggest cytologic screening is slightly less sensitive than hrHPV testing in detecting high-grade (grade 2 or 3) cervical intraepithelial neoplasia (CIN).
Some experts recommend anal cytologic screening or high-resolution anoscopy for HIV-positive men and women, but it's worth noting that strategy hasn't been incorporated into any national practice guidelines.

Whether cytologic screening is efficacious in preventing anal cancer remains unproven (though probable), while cytology screening has proved valuable in preventing cervical cancer (though not in a randomized trial).
Digital anal-rectal examination and anal cytologic screening followed by annual screening is recommended in the following women:
Castle and his colleagues analyzed data from a Portland, Ore., cohort of 19,512 women who underwent routine cytologic screening when they were aged 16-94 years at baseline in 1989-1990.
Automated screening instruments have improved the sensitivity of cytologic screening. Computer-assisted automated imaging screens for dark, hyperchromatic cells which are reviewed by CTs ensure the worrisome areas on each slide are examined so further diagnostic information can be provided.
These data support the need for studies of anal cytologic screening of HIV-positive women.
For HPV or cytologic screening, the nurse-midwives collected cervical cells for testing; women received results within two weeks, and those who tested positive were given appointments for colposcopy, biopsy and treatment.
The availability of a non cytologic screening method not requiring a vaginal speculum examination may reduce underscreening in women who have access to health care.
