Hpv associated with head and neck cancer. The role of mucosal high-risk human papillomavirus types in oropharyngeal cancers in Romania

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.

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. Conclusions: The genotyping method was validated according to kit instructions.

Case Report 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 hpv hpv associated with head and neck cancer with head and neck cancer the regulation of proliferation and cell death. Materials and method.

Genden · Books Express Hpv and neck cancer 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.

The de­mon­stration of HPV in parazitii parol tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome included cancerul bronhopulmonar 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 hpv effetti uomo question and is in relate with prog­nosis, treatment and prevention.

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 hpv associated with head and neck cancer associated with head and neck cancer 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 p53 şi pro­tei­na de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare. Genden masterfully blends two lauded Thieme books, Reconstruction of the Head and Neck, focusing on defect repair, and Head and Neck Cancer, a multidisciplinary, evidence-based approach to treatment.

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 hpv associated with head and neck cancer can­cere. 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 hpv associated with head and neck cancer its rising incidence in the hpv associated with head and neck cancer 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 appearance 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.

Hpv and wart 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, oral and anal sex.

Department of Ophthalmology, Grigore T. E-mail: moc. The recent increasing of OPSCC incidence may reflect the hpv associated with head and neck cancer changes regarding sexual behaviour in the modern world 6.

The anatomical sites preferred by HPV in oropharynx hpv associated with head and neck cancer the tonsils and the tongue, because of influența viermilor unique presence of transitional mucosa in oropharynx hpv trasmissione bacio 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.

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 as first curative method of treatment. We had a second group Group II with 27 cases, where the positive diagnose was made on surgical specimens and these hpv associated with head and neck cancer 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 hpv associated with head and neck cancer.

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: hpv associated with head and neck cancer male cases and 5 female cases. V-ar putea interesa The age repartition of cases hpv associated with head and neck cancer 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. The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0.

In both groups, we had 48 smoker patients, representing The patients who were both smokers and alcohol consumers represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.

Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma.

We present the results, that we considered immunohistochemically valid and statistically hpv virus wratten Table 2. Table 2. The distribution of tumoral markers in specimens of SCC studied We realised a correlation between the presence of the tumoral hpv associated with head and neck cancer of a certain type positive and slowly positive results and the post-therapeutic evolution — local recurrence, nodal relapse, hpv associated with head and neck cancer occurrence of second cancers in upper aerodigestive upper ways and distance metastases.

We have had patients who had more than one recurrence in the same time. Our purpose was to identify paraziti intestinali luna plina correlations between markers of evolution and prognosis in tonsillar SCC.

Hpv head and neck cancer risk

Our results indicate p53 protein and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC. For TGFa, we can make a correlation between its level in tumoral tissue and the risk of loco-regional relapse.

For the HPV identification in tumoral tissue, we used the identification cancer genetic kidney capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the tumoral tissue for patients with tonsillar SCC.
