Do polyomavirus hominis strains BK and JC play a role in oral squamous cell carcinoma?

Introduction: Head and neck cancers are the most common cancers worldwide. It is estimated that approximately 90% of all head and neck cancers are represented by squamous cell carcinoma (SCC). There are many risk factors causing this type of cancer, including environmental factors and lifestyle choices, such as tobacco smoking or abusing alcohol.

Prevalence of EBV genotypes in Polish, Taiwanese and Arabic healthy students and association between genotypes and 30-bp deletion in the LMP-1 gene phylogenetic analysis.

The aim of this study was to compare the prevalence of EBV genotype and del-LMP-1 in saliva from Polish, Taiwanese and Arabic healthy students. The study group consisted of 56 healthy students; 24 of them Polish, 25 Taiwanese, and 7 Arabic. Typing was carried out using PCR with EBNA-2 primers.

Short-fragment PCR assay for highly sensitive broad-spectrum detection of human papillomaviruses in laryngeal squamous cell carcinoma and normal mucosa: clinico-pathological evaluation.

The aim of the study was to determine the prevalence and genotypes of HPV infection in laryngeal cancer specimens, normal mucosa obtained from the surgical margin and laryngeal nodules using a novel high sensitive and specific SPF(10) HPV DNA test, PCR/DEIA method and INNO-LiPA genotyping assay. The correlation between HPV presence and clinico-pathological features was analyzed. Tissue samples were collected from 93 primary laryngeal squamous cell carcinoma (LSCC), 49 specimens of normal mucosa and from 22 specimens of laryngeal nodules serving as control group.
