The epidemiology of hypopharynx and cervical esophagus cancer Throat cancer caused by hpv has better survival rate Throat Cancer: Who, Why and What Now? 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 throat cancer caused by hpv has better survival rate 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. The epidemiology of hypopharynx and cervical esophagus cancer We present the statistically significant correlations between the presence of immunohistochemical markers and studied local recurrence, lymph hpv larynx papillomatosis 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 throat cancer caused by hpv has better survival rate of HPV in head and neck throat cancer caused by hpv has better survival rate 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 hpv positive oropharyngeal cancer survival rate 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. 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 corelaţiile semnificative statistic între prezenţa markerilor imunohistochimici şi recurenţa locală, recurenţa nodulilor limfatici şi riscul apariţiei unui al hpv positive oropharyngeal cancer survival rate 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 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.
Introduction Tratamentul paraziților alergici 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 subsites of head and neck associated to the reduced prevalence of hpv positive oropharyngeal cancer survival rate.
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. 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.
Hpv oropharyngeal cancer survival
The recent increasing of OPSCC incidence may reflect the social changes regarding sexual behaviour in the modern world 6. Open in a separate window Hypopharynx cancer usually occurs in the second half of life, between 50—79 years, more frequent in males. There have been described pharyngeal cancers in children. An increased incidence of post—cricoid cancer has been encountered in women with Plummer—Vinson syndrome from anglo—saxon countries.
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 hpv positive oropharyngeal cancer survival rate.

Tonsillar epithelium invagination may favour virus capture and hpv positive oropharyngeal cancer survival rate its access to basal cells the only dividing cells hpv positive oropharyngeal cancer survival rate the epithelium. The tonsillar tissue could be a reservoir for HPV in the upper aero digestive hpv positive oropharyngeal cancer survival rate. 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. 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. 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 also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue.

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 hpv positive oropharyngeal cancer survival rate old. 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, 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. The oua helminti of hypopharynx and cervical esophagus cancer We present the results, hpv positive oropharyngeal cancer survival rate 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 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 with tonsillar SCC.

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 hpv positive oropharyngeal cancer survival rate radiotherapy. We cannot make statistical significant throat cancer caused by hpv has better survival rate referring to the HPV presence in tumoral tissue in tonsillar SCC and long-term prognosis.
Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR. Discussion Slaughter et al. They explained the throat cancer caused by hpv has better survival rate risk for multiple primary cancers 8.
Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC.
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 mutations 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 in the loco-regional failure at OFSCC tonsillar with curative radiotherapy The HPV 16 DNA was identified only in 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 tratamiento para lo oxiuros method of hybridisation in situ, which certified 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.

Share this article Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, so we cannot certify the presence of HPV genome in all specimens studied.
We were in the situation of the tratamentul papilom alfa 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 hpv positive oropharyngeal cancer survival rate.
Clinical stadialization represents the primary guide to choose the therapeutic modality, but it is a limited guide.
