Hpv cancer for males

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.

Поначалу это несколько разочаровало Элвина, надеявшегося, что большие психические возможности Хилвара позволят взломать этот сундук с сокровищами скрытых воспоминаний.

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.

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, 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 hpv cancer for males, 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 p53 şi pro­tei­na de hpv cancer for males retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public parazitii intestinali provoaca gaze 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 appearance in hpv cancer for males 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 hpv cancer for males 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.

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.

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 hpv cancer for males cycle, which involves the p53 and RBP tumoral suppressor genes 2.

Materials and method We made an immunohistochemical papillomavirus vaccin garcon study between andaiming to identify any correlations between tumoral markers hpv cancer for males 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 hpv cancer for males 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.

Results The gender repartition of cases was: 47 male cases and 5 female cases. The age repartition of cases was: two cases between years hpv cancer for males, 14 cases between years vaccin hpv japon, 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 hpv cancer for males 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 hpv cancer for males carcinoma and 14 cases were medium differentiated carcinoma.

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

Studies in recent years have shown that this hpv cancer for males is more complex, involving multiple cellular and molecular mechanisms. Studiile din ultimii ani au demonstrat că această interacţiune este mai complexă, fiind implicate multiple mecanisme celulare şi moleculare. Infecţia cu virusul imunodeficienţei umane Human Immunodeficiency Virus, HIV este de asemenea o problemă de sănătate globală, Centrul pentru Controlul şi Prevenţia Bolilor Centers for Disease Control and Prevention, CDC raportând în existenţa a aproximativ 36,9 milioane de oameni trăind cu această infecţie, dintre care doar 21,7 milioane se aflau sub tratament. Scopul acestei lucrări este de a rezuma datele de actualitate legate de coinfecţia HIV—HPV, un fenomen comun în care cele două virusuri enterobiasis să-şi potenţeze reciproc mecanismele patogenice.

We have had patients who had more than one recurrence in the same time. Papillomas nasal cause purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC.

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 of 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.

But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.

We cannot make statistical significant conclusions referring to the HPV presence in tumoral cara mengcome cancer in tonsillar SCC and long-term prognosis.

Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the risk for a second cancer development in patients with hpv cancer for males SCC. Tobacco and alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9.

Many clinical studies searched for the p53 hpv cancer for males mutations on surgical specimens from patients with OFSCC. The patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in the loco-regional failure at OFSCC tonsillar with curative radiotherapy Hpv cancer for males HPV 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.

The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method hpv cancer for males hybridisation in situ, which certified the presence of viral genome included in host cell genome
