Oral cancer screening using cytopathology: An advanced proposal with the Bethesda classification.
Background: Oral cancer screening requires analysis capable of detecting changes preceding the clinical manifestation. Oral cytopathology studies as an oral cancer screening have shown promising results. This study aims to evaluate the use of cytopathology in a quali-quantitative analysis using Papanicoloau staining.
Methods: Four experimental groups were evaluated: control (CG), exposed to carcinogens (EG), potentially malignant disorder with and without epithelial dysplasia (D-OPMDG and ND-OPMDG) and oral squamous cell carcinoma (OSCCG). Oral smears were collected using a Cytobrush® and conventional exfoliative cytology.
Results: Oral Papanicolaou smears from 143 individuals were analysed in 8100 images. Qualitatively, non-lesional groups exhibited minimal suspected cases (20% in CG and 5% in EG), in the OPMD groups the ability to identify altered cells was low (40% in D-OPMDG and 0% in ND-OPMDG). Conversely, a notable 100% accuracy was achieved in the OSCCG. Quantitatively, a higher percentage of anucleated and a lower percentage of intermediate cells were observed in the OPMDG; a higher proportion of parabasal/suspicious cells was observed in OSCCG. The optimal threshold for improved accuracy in detecting suspected malignancies occurs when the count of parabasal/suspicious cells exceeds 8/100 cells examined. Cytomorphometric analysis revealed a higher nucleus/cytoplasm ratio (N/C) in OSCCG, with a best cutoff point indicating enhanced accuracy in discerning suspected malignancies when exceeding 17% of cells exhibiting this elevated ratio.
Conclusion: It is possible to suggest updates in cytomorphometric and quantitative analysis in the modified Bethesda system for the oral cavity including objective criteria in the risk classification, therefore improving oral cancer screening.
期刊介绍:
The aim of Cytopathology is to publish articles relating to those aspects of cytology which will increase our knowledge and understanding of the aetiology, diagnosis and management of human disease. It contains original articles and critical reviews on all aspects of clinical cytology in its broadest sense, including: gynaecological and non-gynaecological cytology; fine needle aspiration and screening strategy.
Cytopathology welcomes papers and articles on: ultrastructural, histochemical and immunocytochemical studies of the cell; quantitative cytology and DNA hybridization as applied to cytological material.
