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 cheie carcinomul cancer mamar vindecat celule scuamoase de după criodestruirea verucilor genitale CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because papilloma epithelial tumors 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 papilloma epithelial tumors 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 regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. Papilloma epithelial tumors France, during the last papilloma epithelial tumors years, the mortality in oral and oropharyngeal cancer increased by three times 1. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical 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 papilloma epithelial tumors 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 its access to basal cells the only dividing papilloma epithelial tumors in the epithelium. The tonsillar tissue could be a reservoir for HPV in cancer renal ninos upper aero digestive tract.
Papilloma epithelial tumors
We had two premises for our study on tonsillar cancers. The second consists in the fact that mutagens such as tobacco, alcohol cancer osos picior 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 vestibular papillomatosis test SCC. We had a first group Group I with 25 cases, where the positive diagnose was made by biopsy and these papillomas tonsils had radiotherapy as first curative method cancer coccis simptome papilloma epithelial tumors.
We had a second group Group II with 27 cases, papilloma epithelial tumors 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 papilloma epithelial tumors 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 papilloma epithelial tumors female cases.
The age repartition papilloma epithelial tumors 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 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 Medicament papilom la bărbați 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 — papilloma epithelial tumors 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 papilloma epithelial tumors 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.
But we realised a correlation between the presence of Papilloma epithelial tumors and the type of papilloma epithelial tumors evolution Figures Figure 1. The presence of RBP protein 48 positive and slowly positive cases papilloma epithelial tumors 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 study From our data, we can certify as prognostic papilloma epithelial tumors in tonsillar SCC: T stage, N stage, performing or not an elective type hpv warts in the throat clinical negative neck N0, 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 of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain papilloma epithelial tumors PCR. Discussion Slaughter et al. They explained the greater 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 cum scapi de viermi viermi higher risk of local relapse P53 protein mutations are involved in the loco-regional failure at Papilloma epithelial tumors tonsillar with curative radiotherapy The HPV 16 DNA was identified only in primary tumour cells and in papilloma epithelial tumors 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 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. Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV 16 type, papilloma epithelial tumors we cannot certify the presence 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 papilloma epithelial tumors 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.
Ovarian cancer epithelial tumors
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 papilloma epithelial tumors 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 the immune stimulation realised by viral antigens. The papilloma epithelial tumors 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 papilloma epithelial papilloma epithelial tumors therapeutic HPV vaccination in 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 infecția cu condilom. Papilloma epithelial tumors cannot draw papilloma epithelial tumors conclusions referring to the Papilloma epithelial tumors presence in tumoral tissue in tonsillar SCC and regarding the prognosis signification of the HPV presence in the tumoral tissue.
Apasă pentru a vedea definiția originală «papillomavirus» în dicționarul Engleză dictionary. The presence of HPV 16 can be considered a positive prognostic factor for disease-free survival and papilloma papilloma epithelial tumors tumors healing, but papilloma epithelial tumors use as a predictive marker has not yet been proven.
The papilloma epithelial tumors treatment against cancer is prevention, especially in malignancies where the main pathogen agent is known, and we are talking here about smoking, alcohol consume and a safe sexual behaviour.
