Abstract
Background To validate oral exfoliative cytology in the analysis of the microRNA expression profile in Oral Lichenoid Disease (OLD). Material and Methods The expression of 13 microRNAs identified and presented by our group in a previous study was analyzed in 26 cases, 16 diagnosed as OLD and 10 controls with no oral mucosal pathology. Cytological samples from the oral mucosa obtained using an Orcellex toothbrush were analyzed using RT-qPCR and TaqMan microRNA assays. Results The aberrant expression was validated for 2 microRNAs (miR-146a-5p and miR-7-1-3p) of those previously recognized in the biopsy study. Conclusions This is the first time that oral exfoliative cytology is validated in a study of the alterations of the expression of microRNAs in OLD. The alteration of miR-146a and miR-7 compared to controls was validated. These microRNAs are associated with both inflammatory and carcinogenic phenomena that are involved in the etiopathogenesis of this potentially malignant oral disorder. Key words:microRNAs, lichen planus, epigenetics, cytological techniques.

Abstract
OBJECTIVE To dissect the aberrant microRNA profile of oral lichenoid disorders (OLD) by analyzing the larger set of OLD samples tested so far. MATERIALS AND METHODS MicroRNA expression profiles were assessed using TLDA card in 32 samples (16 OLD, 8 OSCC, and 8 control). The findings were validated using RT-qPCR in an independent cohort of 91 samples. RESULTS We identified 20 differentially expressed microRNAs in OLD, of which several are functionally related to cell proliferation, response to organic substances, or immune processes. Further validation of the top-ranked microRNAs revealed that they were all aberrantly expressed in OLD. CONCLUSION We have identified a new microRNA signature associated with OLD that may provide a meaningful basis for better understanding the physiopathology of the disease. In addition, we validated seven microRNAs whose expression was shown to be higher in OLD tissue in comparison with the control and OSCC tissues.

Abstract
Background: Oral lichen planus (OLP) is one of the potentially malignant disorders (PMDs) with a malignancy rate of 0.2-2%. Aneuploidy is considered to be one of the important markers for malignant transformation and DNA-image cytometry (DIC) has been successfully employed in oral mucosal PMDs and also in tumors of the cervix, lung and biliary tract. Aims: In this study, we intend to assess the ploidy status of exfoliated cells in OLP using DIC. Materials and Methods: Exfoliated cells from 48 patients with different subtypes of OLP (reticular, plaque type, erosive and atrophic) and 10 controls were stained using Feulgen reaction and assessed for integrated optical density using image analysis software and the ploidy status was assessed. Results: All the patients in the control group and most of the patients (93.5%) who had reticular or plaque type of OLP (29 out of 31) exhibited diploid nuclei in the smears, whereas 11 patients who had erosive or atrophic types of OLP showed aneuploid nuclei. Conclusions: The patients with erosive or atrophic types of OLP are at more risk and assessment of ploidy status by exfoliative cytology can be used as an adjuvant for diagnosis.

Abstract
BACKGROUND Oral leukoplakia (OL) is the best-known potentially malignant disorder of oral cancer. The hypothesis was tested that DNA content abnormality may contribute to risk prediction of malignant potential of OL. METHODS All OLs were staged according to a clinicopathologic classification and OL-staging system. DNA content status was investigated in a blinded prospective series of OL using brush biopsy with image cytometry, and examined the correlation of DNA content with the clinicopathologic features and OL-staging system in this preliminary study. RESULTS Among 65 patients with OL, 27 (41.5%) was identified as DNA content abnormality. The frequency (77.8%) of DNA content abnormality in tongue was higher than that (22.2%) in other oral sites (χ(2) test, P=0.038), and moderate or severe dysplasia had a higher frequency (63.0%) of DNA content abnormality than that (37.0%) of no or mild dysplasia (χ(2) test, P=0.022). Moreover, the odds ratio of DNA content abnormality in high-risk patient group was 5.74-fold (95% confidence interval, 1.81-18.20; P=0.003) increase compared with low-risk patient group. Importantly, the positive correlation between OL-staging system and DNA content status was significant (P=0.018, correlation coefficient=0.292). CONCLUSION Our findings showed that DNA content status correlated with OL-staging system, suggesting that DNA content abnormality in OL as detected by image cytometry was an early event in oral carcinogenesis. The further large-scale prospective studies with clinical endpoints are warranted to validate the value of DNA image cytometry.

Abstract
OBJECTIVES Accumulating evidence indicates that aberrant DNA methylation is closely related to oral carcinogenesis, and it has been shown that methylation changes might be used as prognostic biomarker in oral squamous cell carcinoma. Oral lichenoid disease (OLD) is the most common oral potentially malignant disorder in our region. The aim of this study was to perform the first wide DNA methylation study in OLD in order to investigate the relevance of DNA methylation changes in this premalignant disorder. MATERIALS AND METHODS Two different Illumina microarray platforms, namely the GoldenGate Cancer Panel I and the HumanMethylation27 DNA Analysis BeadChip, were utilized in the discovery phase to interrogate the methylation profile of 59 OLD cases and 9 healthy individuals. Top-ranked genes were further validated by pyrosequencing in a second sample set consisting of 160 OLD and 65 controls. RESULTS Our results show that the frequency of aberrant DNA methylation is rare in OLD, and this finding was further corroborated by pyrosequencing in the biological validation. CONCLUSIONS These findings reinforce the notion that molecular alterations associated with oral carcinogenesis do not seem to be common events in OLD, which in turn might explain the low rate of malignization of this disorder.

Abstract
OBJECTIVE This study evaluated whether quantitative cytology (QC) can disclose abnormal DNA content (aneuploidy) and abnormal nuclear morphology of high-risk potentially malignant disorders (PMDs) of the oral mucosa found in the community in reference to clinicohistopathologic features. STUDY DESIGN A total of 171 patients at community-based clinic with suspicious oral lesions were evaluated with concurrent but independent histopathologic and QC assessments. RESULTS QC-positive results were associated with oral lesions with higher clinical risk factors: large size, nonhomogeneous surface texture, and located at high-risk anatomic sites. Only 3% of benign/reactive and 5% of low-risk PMDs were QC positive, while 92% of high-risk PMDs and 88% of squamous cell carcinomas (SCCs) were QC positive. The sensitivity and specificity of QC for detection of high-grade dysplasia/SCC were 89% and 97%. CONCLUSIONS QC could serve as an adjunctive tool for the detection of high-risk PMD/SCC requiring immediate clinical care.
