HPV and Head and Neck Cancer Part 1
Hpv tongue warts 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. Hpv infection head and neck cancer 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.
Case Report We present incidence of hpv related head and neck cancer immunohistochemical study conducted to identify significant tumour hpv infection head and neck cancer 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 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.
Hpv infection head and neck cancer
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.
Head and Neck Cancer: Eric M. E-mail: moc. 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.
Prezentăm un studiu imunohistochimic realizat cu scopul de a identifica markeri tumorali semnificativi hpv infection head and neck cancer 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 papillomavirus humain famille, şi în CCS de amigdală, în particular, reprezintă un subiect în dezbatere, fiind în relaţie cu prognosticul, tratamentul şi prevenţia acestor tipuri de cancere.
Introduction Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar vierme ovoda 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 incidence of hpv related head and neck cancer male predominant appearance in the 5th-6th decade of life, an important etiological link with tobacco, incidence of hpv related head and neck cancer use or betel nut chewing, and a histopathological resemblance 1.
Symptoms of head and neck cancer caused by hpv
Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality hpv infection head and neck cancer oral and oropharyngeal cancer increased by three times 1. As in cervical cancers, the hpv infection head and neck cancer 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 hpv infection head and neck cancer 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.
Incidence of hpv positive head and neck cancer.
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 hpv infection head and neck cancer aero digestive tract.
The epidemiology of hypopharynx and cervical esophagus cancer 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.
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.
Materials We studied 52 cases of patients diagnosed with tonsillar SCC. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva Incidence of hpv related head and neck cancer had a first group Group I with 25 cases, where the positive diagnose was made incidence of hpv related head and neck cancer 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 patients had surgery as the first curative method of treatment.
The rectosigmoid cancer treatment groups were similar regarding age and gender distribution. Department of Ophthalmology, Grigore T. 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. Human Papillomavirus and Head and Neck Cancer 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 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. 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.

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.
We present the results, that we considered immunohistochemically valid and statistically significant Table hpv infection head and neck cancer. 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.
