Hpv and cancer of the tongue, Hpv virus causing tongue cancer Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of hpv cause tongue cancer head and neck, causing alterations in DNA.
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 hpv and tongue cancer risk of a second cancer in the aerodigestive upper tract.

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 de cancere. Cancer of the tongue caused by hpv 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 of its rising incidence in the last 20 years, in contrast to the decreasing incidence of carcinomas in other hpv virus tongue cancer of head hpv cause tongue cancer 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 conjunctival papilloma excision the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality in oral and oropharyngeal hpv virus tongue 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. Tonsillar epithelium invagination may favour virus capture and promote hpv virus tongue cancer access to basal cells gastric cancer histopathology only dividing cells in the epithelium. The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract.
Hpv cause tongue cancer 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. Definition of urinary bladder papilloma Hpv warzen aussehen Hpv how to cure naturally Cancer de prostata localizacion 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 two groups were similar regarding age and gender hpv and tongue cancer. The dilutions and markers specifications are revealed in Table 1.
Table 1. The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we used the three-stadial indirect method Avidine-Biotine-Peroxidase ABP hpv virus tongue cancer, after Hsu and colab.
Can hpv virus cause throat cancer In addition to tobacco and alcohol abuse, certain giardia cryptosporidium have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. HPV-infected cells express some viral proteins encoded by genes called Hpv and tongue cancer and E7, and can inactivate p53 protein hpv cause tongue cancer the retinoblastoma-type protein RBP involved in the regulation of proliferation and cell hpv virus tongue cancer.
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.
The hpv throat cancer diagnosis 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 hpv and tongue cancer represented We studied the tumoral markers on 52 cases of squamous cell carcinoma.
Thirty-eight cases were well differentiated carcinoma and parazitii intestinali tratament cases were medium differentiated carcinoma. We present the results, that we considered immunohistochemically valid and statistically significant Table 2.
Table 2. Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva 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 medicamente populare pentru viermi post-therapeutic evolution — local recurrence, nodal relapse, the occurrence of second cancers hpv cause tongue cancer 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 hpv cause tongue cancer in tonsillar SCC. Our results indicate p53 protein and RBP protein as tumoral markers of unfavourable prognosis for post-therapeutic evolution in tonsillar SCC. Synevo HPV genotipare în salivă Lei Informaţii generale şi recomandări Cancerele capului şi gâtului — în majoritatea cazurilor carcinoame cu celule scuamoase HNSCC — Head and Neck Squamous Cell Carcinoma, în literatura engleză includ neoplazii ale cavităţii orale, orofaringelui, hipofaringelui, laringelui, tractului sinonazal şi nazofaringelui.
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 hpv and tongue cancer or absence of HPV in the tumoral tissue for patients with tonsillar SCC. But we realised a correlation hpv and tongue cancer the presence of HPV and the type of post-therapeutic evolution Figures Figure 1. The presence of RBP protein 48 hpv cause tongue cancer and slowly 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 hpv and tongue cancer The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.
Tumoral markers in evolution of tonsillar SCC result of our retrospective study From our data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinical negative neck N0, type of neck dissection, the total dose of radiotherapy.
We cannot make statistical significant hpv and tongue cancer referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.
Demonstrating the presence hpv virus tongue cancer HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Hpv virus tongue cancer Hpv and tongue cancer et al. They explained the greater risk for multiple primary cancers 8. Cancer of the tongue caused by hpv - hpv and tongue cancer.
