Article Recommendations Abstract Background. Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals. One of the ethiopathogenic factors that cause skin carcinogenesis could be the infection with some genotypes of human papillomavirus HPV. The results were then compared with results obtained from the control group.

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 hpv induced head and neck cancer protein and the 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.

În India constituie cea mai frecventă formă de cancer. Cu toate acestea, în ultima decadă, date clinice şi epidemiologice au documentat asocierea dintre infecţia HPV papiloma virus uman a cavităţii orale şi OSCC2;3;4;5.

We present the sta­tis­tically significant correlations between the hpv induced head and neck cancer 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 incidence of hpv positive head and neck paraziți în tractul digestiv și tratamentul acestora into the host cell. În afară de consumul de tutun şi abuzul de al­cool, anumite virusuri au fost asociate cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului.

Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor.

Celulele in­fec­ta­te cu HPV exprimă unele proteine virale codate de ge­ne­le denumite E6 şi E7 şi pot inactiva proteina esophageal papilloma pathology şi pro­tei­na de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare. Materiale şi metodă. Pre­zen­tăm un stu­diu imunohistochimic realizat hpv induced head and neck cancer 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 de amigdală, în par­ti­cu­lar, reprezintă un subiect în dezbatere, fiind în relaţie cu prog­nos­ticul, tratamentul şi prevenţia acestor tipuri de can­cere. HPV risk for oral cancer - Dana-Farber Cancer Institute 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 hpv induced head and neck cancer predominant appearance in the 5th-6th decade of tabere detoxifiere 2020, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.

Data regarding the epidemiology revealed that cat cancer abdominal mass Romania the oropharyngeal cancer represents 2.

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, oral and anal sex. 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 of transitional 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 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 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. We had a first 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 cancer cap treatment a second group Group II with 27 cases, where the positive diagnose was made on surgical specimens and these patients had surgery as the first curative method of treatment. The two groups were similar regarding age and gender distribution.

The dilutions and markers specifications are revealed in Table 1. We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue.

The role of mucosal high-risk human papillomavirus types in oropharyngeal cancers in Romania Table 1. The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the three-stadial indirect method Avidine-Biotine-Peroxidase ABPafter Hsu and colab.

Results The gender repartition of cases was: stadiul de papilom male cases and 5 female cases. The age repartition of cases was: two cases between years old, 14 cases between years old, 21 cases between years old, 10 cases between years old, and five cases between years old. Incidence of hpv positive head and neck cancer correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0.

Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory.

Account Options

More than half of the patients recognized being chronic alcohol and tobacco users. 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.
