Megjegyzések:In a previous pilot study, a significantly poorer outcome of laryngeal cancer was found in patients co-infected with human papillomavirus (HPV) and genogroup 1 torque tenovirus (TTV). The present study aimed to collect data on the overall prevalence of TTVs on the prevalence of genogroup 1 TTV in two other malignancies associated with HPV,oralsquamouscell cancerandcervical cancer, and in oral and cervical premalignant lesions (oral lichen planus, oral leukoplakia, cervical atypia). Oral samples from all patients were accompanied with asamplefromthehealthymucosa.Theoverall prevalence of TTV was significantly higher both in oral squamous cell cancer and cervical cancer compared with other patient groups or with the respective controls.The prevalenceofgenogroup 1 TTV was significantly higher in lesions of oral squamous cell cancer and oral lichen planus, but not in lesions of oral leukoplakia (24.6%, 10.1%, and 4.5%, respectively), compared with the prevalence in the oral cavity of controls (1.4%). Co-infection rates with genogroup 1 TTV and HPV were significantly higher in oral squamous cell cancer than in controls, oral lichen planus or oral leukoplakia patients (12.3%, 0.0%, 6.7%, and 4.5%, respectively). The prevalence of genogroup 1 TTV in all cervical samples were comparable. These data suggest that genogroup 1 TTV may be associated specifically with some head and neck mucosal disorders, but disproves a (co)carcinogenic role inoral canceror cervical cancer aswell as an association with HPV or with malignancies associated with HPV.

Cím:Frequency of Genetic and Epigenetic Alterations of p14ARF and p16INK4A in Head and Neck Cancer in a Hungarian Population / Andrea Kis, Tímea Zsófia Tatár, Tamás Gáll, Róbert Boda, Ildikó Tar, Tamás Major, Pál Redl, Lajos Gergely, Krisztina Szarka

Megjegyzések:Occurrence of genetic and epigenetic alterations affecting p14ARF and p16INK4A were investigated in tumour samples of 37 oral (OSCC) and 28 laryngeal squamous cell cancer (LSCC) patients, and compared to exfoliated buccal epithelial cells of 68 healthy controls. Presence of deletions and mutations/polymorphisms affecting exons were examined using sequencing. Methylation status of promoters was assessed by methylation-specific PCR. Chi-square and Fisher's exact tests were used to compare frequency of events. Exon deletions were found in four controls, one OSCC and 22 LSCC patients; the latter significantly differed from controls (p<0.001). Only two mutations (T24610A and C24702A) were in p16 exon 1 of two OSCC patients. Polymorphisms G28575A (Ala140Thr), G31292C (C540G) and G28608A were found in both patient groups. The p14 promoter was unmethylated in 86.7 % of OSCC and in 85.7 % of LSCC patients; for the p16 promoter these rates were 69.0 % and 76.2 % for OSCC and LSCC patients, respectively. Combining the two patient groups, unmethylated promoter was significantly less frequent in case of both p14 and p16 (p=0.043 and p=0.001, respectively) compared to the control group. In summary, exon deletion may be important in LSCC, while promoter methylation was relatively frequent in both patient groups.

Cím:Epstein-Barr virus prevalence in oral squamous cell cancer and in potentially malignant oral disorders in an eastern Hungarian population / Kis Andrea, Fehér Enikő, Gáll Tamás, Tar Ildikó, Boda Róbert, D. Tóth Etelka, Méhes Gábor, Gergely Lajos, Szarka Krisztina
Dátum:2009
Megjegyzések:We tested 65, 44, and 116 patients with oral squamous cell cancer (OSCC), oral leukoplakia (OL), and oral lichen planus (OLP) against 68 age-matched controls for the presence of Epstein-Barr virus (EBV). Apparently healthy mucosa was simultaneously sampled and examined in all patients. Paraffin-embedded tissue sections of all EBV-positive patients with OSCC were examined for latent membrane protein-1 (LMP-1) expression (demonstrable in most EBV-associated malignancies) using immunohistochemistry. The prevalence of EBV in the controls and in OSCC, OL, and OLP lesions was 19.1%, 73.8%, 29.5%, and 46.6%, respectively, and 66.2%, 22.7%, and 31.9% in the healthy mucosa of patients, respectively. The prevalence of EBV in OSCC patients was significantly higher than in controls or in respective samples of the other two patient groups both in the lesion and in the healthy mucosa. Comparisons including only patients with EBV-negative lesions yielded similar results. Lesions of patients with OLP, but not of patients with OL, differed significantly from controls in EBV prevalence. In OSCC, LMP-1 expression was not detected, and EBV carriage was not significantly associated with any risk factors and did not influence the outcome. Although a high prevalence of EBV was found in OSCC, comparable carriage rates on healthy mucosa of patients indicated that an aetiological role of EBV is unlikely.

Cím:Progressive increase of human papillomavirus carriage rates in potentially malignant and malignant oral disorders with increasing malignant potential / Szarka Krisztina, Tar Ildikó, Fehér Enikő, Gáll Tamás, Kis Andrea, D. Tóth Etelka, Boda Róbert, Márton Ildikó, Gergely Lajos
Dátum:2009
Megjegyzések:We investigated the potential role of human papillomaviruses (HPVs) in potentially malignant oral disorders, oral leukoplakia (OL) and oral lichen planus (OLP), and in oral squamous cell cancer (OSCC) in an Eastern Hungarian population with a high incidence of OSCC. Methods: Excised tumor samples (65 OSCC patients) and exfoliated cells from potentially malignant lesions (from 44 and 119 patients with OL and OLP, respectively) as well as from healthy controls (72 individuals) were analysed. OLPs were classified based on clinical appearance, 61 patients had erosive?atrophic lesions (associated with higher malignancy risk, EA-OLP) and 58 had non-erosive non-atrophic lesions (with lower risk of becoming malignant, non-EA-OLP), respectively. Exfoliated cells collected from apparently healthy mucosa accompanied each lesion sample. HPV was detected by MY/GP polymerase chain reaction (PCR) and genotyped by restriction analysis of amplimers. Copy numbers in lesions were determined using real-time PCR. Prevalence rates, copy number distributions, and association with risk factors and diseases were analysed using chi-square test, t-test, and logistic regression, respectively. Results: We detected HPVs significantly more frequently in lesions than in controls (P ? 0.001 in all comparisons). HPV prevalence increased gradually with increasing severity of lesions (32.8, 40.9, and 47.7% in OLP, OL, and OSCC, respectively). Copy number distribution patterns roughly corresponded to prevalence rates, but OLP and OL were comparable. HPV prevalence differed significantly between EA-OLP and non-EA-OLP groups (42.6 vs. 22.4%); EA-OLP group showed a prevalence similar to that found in OL. Conclusion: HPVs may be involved in the development or progression of not only OSCC but also of potentially malignant oral lesions.
