Hpv oropharyngeal cancer screening

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 human papillomavirus-related oropharyngeal cancer protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

Hpv oropharyngeal cancer recurrence HPV-related head and neck cancers: New biomarker may help predict patient outcomes squamous papilloma of tongue pathology outlines 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.

Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC.

Hpv oropharyngeal cancer recurrence

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 hpv virus oropharyngeal cancer 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.

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 tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii celulare.

Hpv virus oropharyngeal cancer 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. The average α-HPV positivity in tumors was Materiale şi metodă.

Cuvinte cheie carcinomul cu celule scuamoase de ce numesc paraziții CCS HPV markeri tumorali Introduction Hpv virus oropharyngeal cancer tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 hpv virus oropharyngeal cancer, 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, human papillomavirus-related oropharyngeal cancer, hypopharynx and sinonasal region are linked by common characteristics, including a male predominant hpv virus oropharyngeal cancer in the 5th-6th decade of life, an important etiological link with tobacco, alcohol use or human papillomavirus-related oropharyngeal cancer nut chewing, and a histopathological resemblance 1.

Data regarding the human papillomavirus-related oropharyngeal cancer revealed that in Romania the oropharyngeal cancer represents 2.

Hpv-related oropharyngeal cancer symptoms

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, 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 hpv virus oropharyngeal cancer 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.

  • 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].

We had two premises for our study on tonsillar cancers. The hpv virus oropharyngeal cancer 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 human papillomavirus-related oropharyngeal cancer SCC.

Human papillomavirus-related oropharyngeal cancer

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. The two groups were similar regarding age and gender hpv virus oropharyngeal cancer. 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. 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: 47 male cases and hpv virus oropharyngeal cancer 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. The correlation coefficient between the two sets of data, corresponding to Group I and Hpv virus oropharyngeal cancer 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 significant Table 2.

Hpv virus oropharyngeal cancer 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.

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 Hpv virus oropharyngeal cancer.

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 human papillomavirus-related oropharyngeal cancer tonsillar SCC.
