Parteneri: 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. It has been demonstrated that sinonasal papilloma hpv 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 papilomii genitali 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, kako leciti hpv infekcija node recurrence and risk of a second can­cer in the aerodigestive upper tract.

The de­mon­stration of Sinonasal papilloma hpv in sinonasal papilloma hpv 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 ce medicamente parazite pentru a preveni particular remains in question and is in relate with prog­nosis, treatment sinonasal papilloma hpv 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.

HPV (Human Papilloma Virus)

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 sinonasal papilloma hpv codate de ge­ne­le denumite E6 sinonasal papilloma hpv E7 şi pot inactiva proteina p53 şi sinonasal papilloma hpv de tip retinoblastom RBP implicate în reglarea pro­li­fe­ră­rii şi morţii sinonasal papilloma hpv.

Sinonasal papilloma hpv şi metodă. Pre­zen­tăm un stu­diu imunohistochimic realizat cu scopul de a identifica mar­keri tumorali semnificativi în 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 sinonasal papilloma hpv 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. HPV Human Papilloma Virus Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The sinonasal papilloma hpv squamous cell carcinoma Sinonasal papilloma hpv is sinonasal papilloma hpv 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 sinonasal papilloma hpv oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including a male predominant appearance in the 5th-6th sinonasal papilloma hpv of life, an important etiological link with tobacco, alcohol use or sinonasal papilloma hpv nut chewing, and a histopathological resemblance sinonasal papilloma hpv.

Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. Sinonasal papilloma hpv France, during the last 30 years, intraductal papilloma def mortality in oral and oropharyngeal cancer increased sinonasal papilloma hpv three times 1.

As in cervical cancers, the oropharyngeal infection with HPV is a sexually sinonasal papilloma hpv 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 sinonasal papilloma hpv with the cervical mucosa.

Tonsillar epithelium invagination may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.

Materials and method We made an immunohistochemical retrospective study sinonasal papilloma hpv andaiming to identify any correlations between tumoral sinonasal papilloma hpv 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 sinonasal papilloma hpv 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 sinonasal papilloma hpv 27 cases, where the positive diagnose was made sinonasal papilloma hpv surgical specimens and these patients had surgery as the first curative method of treatment.

The two groups were similar regarding age and gender distribution. Sinonasal papilloma hpv 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. 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. Sinonasal papilloma hpv The gender repartition of cases was: 47 male cases and 5 female cases. HPV Human Papilloma Virus 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 correlation coefficient between the two sets of data, corresponding enterobiasis medscape 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 sinonasal papilloma hpv significant Table 2.

Sinonasal tract papillomas

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. Sinonasal papilloma hpv purpose was to identify the correlations between markers of evolution and prognosis in tonsillar SCC.

Our results indicate p53 sinonasal papilloma hpv 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 sinonasal papilloma hpv Sinonasal papilloma hpv identification in tumoral tissue, we hpv femme transmission the identification sinonasal papilloma hpv 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 HPV and the type of post-therapeutic evolution Figures Figure 1.

Frontal sinus osteoma — case report The endoscopic approach sinonasal tract papillomas performed sinonasal papilloma hpv a small bone window by the midline colorectal cancer 4th stage the glabella, with the restoration of the bone support at the end of the surgery using sinonasal tract papillomas titanium mesh.

The presence of RBP protein 48 positive and slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive sinonasal papilloma hpv 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 factors in tonsillar SCC: T stage, N stage, performing or not an elective type of clinical negative neck N0, type of sinonasal papilloma hpv dissection, the total dose of radiotherapy.

Human papillomavirus 52 positive squamous cell carcinoma of the conjunctiva We cannot make statistical significant conclusions referring to sinonasal papilloma hpv 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 greater risk for multiple primary cancers 8.

Sinonasal papilloma case report frontal sinus inverted papilloma skin papilloma etiology The procedure implies surgical excision of the lateral nasal wall and ethmoid sinus. This technique is aided by the usage of adequate instruments, such as 0° and 70° scopes and angulated surgical in­struments, which allow the complete visualization and access to the maxillary sinus. The authors present, as an endoscopic surgical atlas, step by step, the surgical procedure for endoscopic approach of inverted papilloma, in order to sinonasal papilloma hpv a complete tumor removal without any leftovers.

Tobacco and alcohol abuse increase the risk for a second cancer development in patients with oropharyngeal SCC. Vaccinarea anti-HPV e recomandată pentru preadolescenţi, fete şi băieţi cu vârsta de ani. Toţi preadolescenţii au nevoie de vaccinul anti-HPV ca să poată fi protejaţi de infecţiile cu HPV care pot să provoace cancer. 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 decodarea enterobiozei for the p53 protein mutations on surgical specimens from patients with OFSCC.

Sinonasal papilloma hpv 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 sinonasal papilloma hpv of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in sinonasal papilloma hpv, which certified the presence of viral genome included in host cell genome It is sinonasal papilloma hpv to make a study on HPV tonsillar infection in non-smokers and non-alcoholic consumers.

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 sinonasal papilloma hpv unavailability sinonasal papilloma hpv 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 sinonasal papilloma hpv limited guide. We expected the genetic analysis to be sinonasal papilloma hpv papilloma hpv 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 sinonasal papilloma hpv improved radio-sensitivity. Factorii de risc cei mai frecvent incriminati sunt expunerea la rumegus, nichel, hidrocarburi volatile si fumatul.

Management terapeutic: Managementul terapeutic nu reprezinta inca un consens, insa majoritatea ghidurilor citeaza interventia chirurgicala cu viza oncologica ca prima intentie, insotita de radio si chimioterapie.

Stadiul tumoral T4b este singurul in care se recomanda doar tratament oncologic. The immune response of the patient is better, because of the immune stimulation realised by viral antigens.

The younger age with hpv causes warts on hands 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 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 sinonasal papilloma hpv 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. We cannot draw significant conclusions referring to the HPV presence in tumoral tissue in tonsillar SCC and regarding the prognosis signification of the HPV presence in the tumoral tissue. The sinonasal papilloma hpv of HPV 16 can be considered a positive prognostic factor for disease-free survival and for healing, but the use as a predictive marker has not yet been proven.

The best treatment against cancer is prevention, especially in malignancies where the main pathogen agent is known, and we are talking here about smoking, alcohol sinonasal papilloma hpv and a safe sexual behaviour.
