Megjegyzések:	The aim of this study was to define copy number alterations in a rare laryngeal type basaloid squamous cell carcinoma (laryngeal BSCC) using high throughput array comparative genomic hybridization. This is the first genome wide screening of a laryngeal BSCC describing the unique events of DNA copy number changes. By Nimble-Gen Whole Genome Tiling Array CGH (consisting of 72,000 probes) we were able to identify 3,777 genes altered by copy number changes (1,726 genes with copy number gains and 2,051 genes with copy number with losses). The resolution of the array allowed us to identify a new alteration at the 17q21.31 region covering the DUSP3 gene which encodes the dual-specific protein phosphatase. Functional studies of the altered genes (Database for Annotation, Visualization and Integrated Discovery v6.7 analysis) highlighted molecular pathways including chemokine signaling, cell cycle, adherent junction-, VEGF- and TGF-beta signaling pathways that might be disrupted by copy number alterations in laryngeal BSCC.

Cím:	The characteristics of human papillomavirus DNA in head and neck cancers and papillomas / Major T., Szarka K., Sziklai I., Gergely L., Czegledy J.

Megjegyzések:	Aim: To determine the prevalence, type, physical state, and viral load of human papillomavirus (HPV) DNA in cases of head and neck cancer and recurrent respiratory papillomatosis (RRP). Methods: The prevalence and type of HPV DNA was determined in 27 fresh frozen tissue specimens from patients with head and neck cancers and 16 specimens from 10 patients with RRP by MY09/MY11 and GP5+/GP6+ nested polymerase chain reaction (PCR) and subsequent restriction enzyme cleavage. The physical state of HPV DNA was analysed by E1, E2, and E1E2 specific PCRs and Southern blot hybridisation (SBH). Results: HPV DNA was detected in 13 of 27 cancers and 10 of 10 papillomas. Both low risk HPV-6 and HPV-11 and high risk HPV-16 were present in cancers in low copy numbers, whereas papillomas exclusively harboured low risk HPV-6 and HPV-11. E1E2 PCRs failed to determine the physical state of HPV in cancers except one case where HPV-6 DNA was integrated. In contrast to cancers, all papillomas showed the episomal state of HPV DNA and a relatively higher viral load. Conclusions: Based on the prevalence, type, physical state, and copy number of HPV DNA, cancers and papillomas tend to show a different HPV DNA profile. The 100% positivity rate of low risk HPV types confirms the role of HPV-6 and HPV-11 in the aetiology of RRP.

Cím:	High co-prevalence of genogroup 1 TT virus and human papillomavirus is associated with poor clinical outcome of laryngeal carcinoma / Szladek G., Juhasz A., Kardos G., Szoke K., Major T., Sziklai I., Tar I., Marton I., Konya J., Gergely L., Szarka K.

Megjegyzések:	BACKGROUND: The aetiology and factors leading to the progression of laryngeal cancer are still unclear. Although human papillomavirus (HPV) has been suggested to play a role, reports concerning the effect of HPV infection on tumour development are controversial. Recently, transfusion transmitted virus (TTV) was suggested to play a role in certain infections as a causative or coinfecting agent. AIMS: To investigate whether the development and progression of laryngeal squamous cell carcinoma is associated with coinfection with TTV and HPV. METHODS: The prevalence of TTV and HPV was investigated using the polymerase chain reaction in tissue samples from 40 healthy individuals, 10 patients with recurrent papillomatosis, five patients with papillomatosis with malignant transformation, and 25 patients with laryngeal carcinoma. The obtained prevalence data were compared and analysed statistically. RESULTS: In the 11 patients with carcinoma who had metastasis or relapse there was a high rate of coinfection with genogroup 1 TTV and HPV (eight of 11), whereas in the 14 without tumour progression no coinfection was found. Coinfection was associated with significantly lower tumour free survival in patients with carcinoma (p < 0.001). Furthermore, four of five patients who had papillomatosis with malignant transformation were coinfected with genogroup 1 TTV and HPV. CONCLUSIONS: Although the nature of cooperation between HPV and TTV needs to be investigated further, coinfection with genogroup 1 TTV and HPV appears to be associated with poor clinical outcome in laryngeal cancer.
