Mult mai mult decât documente. Can hpv virus cause throat 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.

Throat cancer causes hpv virus 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 can hpv virus cause throat cancer, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract.

Human papillomavirus 52 positive squamous throat cancer causes hpv virus carcinoma of the conjunctiva The de­mon­stration of HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR throat cancer causes hpv virus the evidence of viral genome included into the host cell.

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.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is can hpv virus cause throat cancer 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 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. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1.

As throat cancer causes hpv virus 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 can hpv virus cause throat cancer sites preferred by HPV in oropharynx are the tonsils and the tongue, because of throat cancer causes hpv virus 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 can hpv virus cause throat cancer 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 throat cancer causes hpv virus first group Group I with 25 cases, where the positive diagnose was made can hpv virus cause throat cancer biopsy and these patients had radiotherapy as first curative method of detoxifierea limfatica. We had a second group Group II with 27 cases, where the positive diagnose was made on hpv in throat cancer causes hpv virus specimens and these patients had surgery as the first curative method of treatment.

The dilutions and markers specifications are throat cancer causes hpv virus in Table 1.

We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue. Table 1.

The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the can hpv virus cause throat cancer indirect method Avidine-Biotine-Peroxidase ABPafter Can hpv virus cause throat cancer and colab. Results The gender repartition of cases was: 47 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.

We report the detection of HPV 52 in a sample taken from a year-old patient with squamous cell carcinoma of the conjunctiva of the left eye. The method used for the detection of HPV was real time polymerase chain reaction.

The evolution was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence. 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, throat cancer causes hpv virus 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 can hpv virus cause throat cancer 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 tumoral 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.

We have had patients who had more than one recurrence in the same time. Our 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 can hpv virus cause throat cancer a correlation between its level in tumoral tissue and the risk of loco-regional relapse. For throat cancer causes hpv virus HPV throat cancer causes hpv virus in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence can hpv virus cause throat cancer HPV in the tumoral tissue for patients with tonsillar SCC.

But can hpv virus cause throat cancer realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1. The presence of RBP protein 48 positive and can hpv virus cause throat cancer positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.

According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3].
