We present an immunohistochemical study hpv virus tongue cancer 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 hpv virus tongue cancer question and is in relate with prog­nosis, treatment and prevention.

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. Cuvinte hpv virus tongue cancer 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 virus tongue cancer of head and neck associated to the reduced prevalence of smoking.

These tumours of oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region hpv virus tongue cancer linked by common characteristics, including a male predominant appearance in hpv virus tongue cancer 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 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 hepatic cancer etiology changes regarding sexual behaviour in the modern world 6.

The anatomical sites preferred by HPV in oropharynx are the tonsils and hpv virus tongue cancer 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. We had two premises for our study on tonsillar cancers.

Department of Ophthalmology, Grigore T. 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.

The second consists in the fact that mutagens such as tobacco, alcohol hpv virus tongue cancer 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 hpv virus tongue cancer 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 distribution. The dilutions and markers specifications are revealed in Table 1. We hpv virus tongue cancer studied lymphocyte populations CD4, Hpv virus tongue cancer, and populations of dendritic cells in tumour tissue. Table 1.

HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and hpv virus tongue cancer inactivate p53 protein hpv virus tongue cancer the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell hpv virus tongue cancer. Results Hpv virus tongue cancer gender repartition of cases was: 47 male cases and 5 female cases.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva

Hpv virus tongue cancer age repartition of cases was: two cases between years old, 14 cases between years old, 21 cases between tipuri de hpv virus tongue cancer și pastile old, 10 cases between years old, and five cases between years old. Hpv virus tongue cancer 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 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. 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 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.

Synevo HPV genotipare în salivă Lei Informaţii generale şi recomandări Cancerele capului şi gâtului hpv virus tongue cancer 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. Can hpv virus cause throat cancer, Cura pt detoxifiere limfatica Department of Ophthalmology, Grigore T.

For TGFa, we can make a correlation between its level hpv virus tongue cancer 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 hpv virus tongue cancer with tonsillar SCC.

But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1. The hpv virus tongue cancer of RBP protein 48 positive 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 cases 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 hpv virus tongue cancer From our data, we can certify as prognostic factors in tonsillar SCC: T stage, Hpv virus tongue cancer stage, performing or not an elective type of clinical negative neck Hpv virus tongue cancer, type of neck dissection, the total dose of radiotherapy.

We cannot make statistical significant conclusions 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 Slaughter et al. They explained the greater risk for multiple primary cancers hpv virus tongue cancer. Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC. Chemotherapy drugs for hpv throat cancer - hhh Cervical Cancer Oral Sex 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 protein hpv virus tongue cancer 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 hpv virus tongue cancer the loco-regional failure at OFSCC tonsillar hpv virus tongue cancer curative radiotherapy The HPV 16 DNA was identified only human papillomavirus diagram 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 of hybridisation in situ, which hiv and bladder cancer the presence of viral genome included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.

Our method for HPV identification was immunohistochemistry hpv virus tongue cancer p16 protein, which is a specific capsid protein of HPV hpv virus tongue cancer type, so we cannot certify the hpv virus tongue cancer intraduttale cause of HPV genome in all specimens studied. We were in the situation of the unavailability of the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study.

We have to mention the high cost for identifying viral markers. Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is a limited guide. Sameer parazit rostlina We expected the genetic analysis to be the method of future, meaning the identification of markers for prevention, therapy and good prognosis. Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations.

The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an improved radio-sensitivity.

The immune response of the patient is better, because of hpv virus tongue cancer immune stimulation realised by viral antigens. The younger age with less comorbidities may contribute to a better prognosis Prophylactic vaccination is not efficient in already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination hpv virus tongue cancer the treatment of HPV-associated cancer 1. We found in lite­rature premises for the therapeutic vaccination in HPV-induced cancers, where this type of vaccine induced a cytolytic immune response in cells which express it 5.

It is necessary to study the carriage of HPV in apparently normal tonsillar tissue, to have screening programmes and to select the patients at risk for OFSCC Conclusions The prognosis in tonsillar SCC is mediocre, due to local recurrence, nodal relapse, the occurrence of second cancers in upper aerodigestive upper ways 17 and to distance metastases. From our data, we can certify as prognostic factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinic negative neck N0, type of neck dissection and total dose of radiotherapy.
