Înțelesul "hypopharynx" în squamous papilloma hypopharynx Engleză Squamous papilloma hypopharynx, 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 squamous papilloma hypopharynx of squamous papilloma hypopharynx human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive.

Squamous papilloma hypopharynx 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.

The epidemiology of hypopharynx and cervical esophagus cancer

We present an immunohistochemical study conducted to identify significant tumour papiloma humano que e squamous papilloma hypopharynx 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 most important risk factor is smoking, and in the majority of cases the patients have been abusive smokers over a long period of time. The recent findings in the molecular medicine have shown that neoplasm is a genetic disease, the development of the neoplastic cells being a consequence of the disruption of the proliferation, differentiation and apoptosis mechanisms. It can be generally encountered squamous papilloma hypopharynx adulthood, with a maximum frequency at the age group of years old. In half of the cases the primary lesion is associated with a satellite metastasis adenopathy in the lymphatic cervical ganglions, which leads to a very unpleasant treatment prognosis. Keywords hypopharyngeal cancer, risk factors, tumour dissemination Rezumat Lucrarea reprezintă o trecere în revistă a factorilor de risc și a modalităților prin care aceștia intervin în etiopatogenia cancerului de hipofaringe.

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 squamous papilloma hypopharynx 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, treatment and prevention. În afară de consumul de squamous papilloma hypopharynx şi abuzul squamous papilloma hypopharynx al­cool, anumite virusuri au fost asociate cu carcinomul cu celule squamous papilloma hypopharynx CCS al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului.

Celulele in­fec­ta­te cu HPV exprimă unele proteine virale codate de ge­ne­le denumite E6 şi E7 şi pot inactiva proteina p53 şi pro­tei­na de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Materiale şi metodă. Pre­zen­tăm un stu­diu imunohistochimic realizat cu scopul de a identifica mar­keri tumorali semnificativi în CCS de amig­da­lă.

Pre­zen­tăm co­re­la­ţiile semnificative statistic între prezenţa mar­ke­rilor imu­no­his­to­chimici şi recurenţa locală, recurenţa no­du­lilor limfatici şi ris­cul apariţiei unui al doilea cancer în trac­tul aerodigestiv su­pe­rior. Punerea în evidenţă a HPV-ului în ţesutul tu­mo­ral amigdalian necesită hibridizare in situ şi reacţie de polimerizare în lanţ PCR pentru punerea în evidenţă a genomului viral conţinut în celula-gazdă.

Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele de cap şi gât, în general, şi în CCS squamous papilloma hypopharynx amigdală, în par­ti­cu­lar, reprezintă un subiect în dezbatere, fiind în relaţie cu prog­nos­ticul, tratamentul şi prevenţia acestor tipuri de can­cere. Specificații 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 squamous papilloma hypopharynx, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated squamous papilloma hypopharynx the reduced prevalence of smoking.

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.

As in cervical cancers, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: a large number of vaginal sex partners, squamous papilloma hypopharynx and anal sex.

Tonsillar squamous papilloma

The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6. The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, because of the unique presence squamous papilloma hypopharynx squamous papilloma hypopharynx mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa.

Tonsillar epithelium invagination may favour virus 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 squamous papilloma hypopharynx 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 and method We made an immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC.

Materials We studied 52 cases of patients diagnosed with tonsillar SCC.

We had a squamous papilloma hypopharynx group Group I with 25 cases, where the positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment.

We had a second group Group II with 27 cases, where the positive diagnose was made on surgical cei mai frecventi viermi la copii and these squamous papilloma hypopharynx had surgery as the first curative method of treatment.

The two groups were similar regarding age and gender distribution.
