HPV infection and oral carcinogenesis
2010
To the Editor,High risk human papilloma viruses (HPV) have been found in head and neck squamous cell carcinomas (HNSCC), particularly in oropharyngeal carcinomas (1). Nevertheless, there are some controversial aspects regarding this issue (2) such as whether the HPV infec-tion is a temporary or a persistent oral infection in these patients.Recently, Chuang et al. (3) have associated the presence of HPV-16 DNA in surveillance salivary rinses with a significant risk for recurrence in HNSCC.We hypothesized that the improved prognosis of many patients with HPV-related oropharyngeal carcinoma is due to the temporary nature of the infection, and there-fore in the absence of lesions no HPV genomic…
Cytometric analysis of oral scrapings of patients with oral lichen planus
2011
A. Acha-Sagredo, Y. Jimenez, J. V. Bagan, M. A. Echebarria-Goicouria and J. M. Aguirre-Utric analysis of oral scrapings of patients with oral lichen planus Objective: Aneuploidy has been associated with malignant and premalignant oral lesions. In the past few years, its application in oral precancerous lesions and its prognostic meaning have been controversial issues. The aim of our study was to characterize alterations in DNA content by automated DNA image cytometry in oral scrapings of patients with oral lichen planus. Methods: Cytological samples from 40 patients clinicopathologically diagnosed with oral lichen planus were analysed by DNA image cytometry. Results: All the cases were c…
