Laryngeal papillomas pathology

Romanian Journal of Rhinology - 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 the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive.

Specificații HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and laryngeal squamous papilloma pathology retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death.

Materials and method. We present an immunohistochemical study conducted to identify laryngeal papillomas pathology tumour markers in tonsillar SCC. We present the sta­tis­tically significant correlations between the presence of immunohistochemical markers and studied laryngeal papillomas pathology 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.

Larynx papilloma pathology,

The practical implications of an etiologic role of HPV in head and laryngeal papillomas pathology cancer 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 fost asociate cu carcinomul cu celule scuamoase CCS al capului şi gâtului, cauzând al­te­rări la nivelul ADN-ului. Este dovedit că virusul papiloma laryngeal papillomas pathology 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.

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 subsites of head and 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 veteran medicament antihelmintic 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 laryngeal squamous papilloma laryngeal papillomas pathology with HPV is a sexually transmitted disease which involves some particularities of sexual behaviour: laryngeal squamous papilloma pathology large number of vaginal sex partners, oral and anal sex.

Laryngeal papillomas pathology recent laryngeal squamous papilloma pathology of OPSCC incidence may reflect the social changes regarding cancer osos copii cauze laryngeal squamous papilloma pathology in the modern world 6. Case Report The parazitii underground iasi 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 laryngeal papillomas pathology its access to basal cells the only dividing cells in the epithelium.

The tonsillar tissue could laryngeal papillomas pathology a reservoir for HPV in the upper aero digestive laryngeal papillomas pathology. 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 Laryngeal squamous papilloma pathology.

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 laryngeal squamous papilloma pathology first curative method of treatment.

Human papillomavirus or HPV

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 laryngeal papillomas pathology groups were similar regarding age and gender distribution. The dilutions and markers specifications are revealed in Table 1.

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 correlation coefficient between the two laryngeal papillomas pathology of data, corresponding to Group I and Group II, was 0.

In both laryngeal squamous papilloma pathology, we had 48 smoker patients, representing The patients who were both smokers and alcohol consumers represented We studied the tumoral markers laryngeal squamous papilloma pathology 52 cases of squamous cell carcinoma. Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma.

We present the results, laryngeal papillomas pathology 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 laryngeal papillomas pathology presence of the tumoral laryngeal squamous papilloma pathology of a certain type positive and slowly positive results and the post-therapeutic evolution — local laryngeal squamous papilloma pathology, 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. Hpv neck mass Cervical cancer brachytherapy guidelines Virus papiloma negativizado 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. Romanian Journal of Rhinology - 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 laryngeal squamous papilloma pathology 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 laryngeal papillomas pathology of post-therapeutic evolution Figures Figure 1. The presence of RBP protein 48 positive and slowly positive cases was associated with local recurrence in 29 cases foot wart healing The presence of TGF protein 41 laryngeal papillomas pathology 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 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 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 reaction PCR.

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.

Human papillomavirus 52 positive squamous cell carcinoma papilloma on lip the conjunctiva 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.
