Relationship of DNA aneuploidy with distinctive features of oral potentially malignant disorders: A cytological analysis of 748 cases.

ABSTRACT: Our previous study reported that clinical features, including the lateral/ventral tongue and non-homogeneous lesions, were associated with increased risk of malignant changes in cytological samples from oral potentially malignant disorders (OPMDs). This cross-sectional study aimed to evaluate the frequency and risk of DNA aneuploidy in the series of 748 patients with OPMD. The cut-off value of aneuploidy was defined as DNA index ≥3.5. We found that the frequency of DNA aneuploidy was higher in OPMD patients >60 years old, and in those with lateral/ventral tongue sites, non-homogeneous lesions, and high-grade dysplasia, than in control group (P < 0.01). Consistently, the risk of aneuploidy occurrence was higher in patients >60 years old (1.69-fold; P = 0.022), in those with la
