Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. More than half of the patients recognized being chronic alcohol and tobacco users.

HUMAN PAPILLOMA VIRUS GENOTYPING IN FRESH HEAD AND NECK TUMORS - OUR FIRST EXPERIENCE

Conclusions: The genotyping method was validated according to kit instructions. To get a general idea on the prevalence of HPV genotypes in head and neck cancer in our region we tested a very small number of samples.

In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

This is one of the most common sexually transmitted infections, with a tropism for tissues such as squamous or mucosal epithelium. Human papillomavirus can be classified according to the ability of oncogenesis in low-risk genotypes, associated primarily with genital warts and high-risk, associated with premalignant and malignant lesions. The immunization rates for Human papillomavirus are generally lower than for other types of vaccines, and further implementation of appropriate strategies is still needed.
