Romanian Journal of Rhinology - 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.

Specificații HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and laryngeal squamous papilloma pathology retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death. Materials and method.

We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC. We present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and studied local re­cur­rence, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract.

The de­mon­stration of HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome included into the host cell. The practical implications of an etiologic role of HPV in head and neck cancer generally and in tonsillar SCC in particular remains in question and is in relate with prog­nosis, squamous papilloma tongue pathology and prevention.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 years, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of smoking. These tumours of oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including a male predominant squamous papilloma tongue pathology in the 5th-6th decade of life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.

Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1.

Case Report The parazitii underground iasi sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence of transitional mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa. Tonsillar epithelium invagination may favour squamous papilloma tongue pathology capture and promote its access to basal cells the only dividing cells in the epithelium.

The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract. We had two premises for our study on tonsillar cancers. The second consists in the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, which involves the p53 and RBP tumoral suppressor genes 2.

Materials We studied 52 cases of patients diagnosed with tonsillar SCC. We had a first group Group I with 25 cases, where the positive diagnose was made by biopsy and these patients had radiotherapy laryngeal squamous papilloma pathology first curative method of treatment.
