Hpv genotip cp6108

Human papillomavirus-positive oropharyngeal Gel Papillor (HPV-positive OPC or HPV+OPC), is a Gel Papillor (squamous cell carcinoma) of the throat caused by the human papillomavirus type 16 virus (HPV16). In the past, Gel Papillor of the oropharynx (throat) was associated with the use of alcohol or tobacco or both, but the majority of cases are now associated with the HPV virus, acquired by having oral contact Causes: Human papilloma virus. 6/4/ · Clinical tests for oncogenic types of HPV are used for 1) cervical Gel Papillor screening in conjunction with a Pap test, 2) triage of abnormal cervical cytology results, and 3) follow-up after treatment of cervical preGel Papillors. These tests are only approved for use with cervical specimens, not oral or anal specimens. HPV 16 is the most frequently detected genotype in this disease and antibodies against HPV 16 E6 are known to be diagnostic for HPV positive invasive cervical Gel Papillor.

Thus, serology may provide an alternative approach to cytology of HPV DNA detection in screening for this hpv.iubescstudentia.ro by: 8. The digene HPV Genotyping PS Test is a reflex test intended for the individual qualitative detection of high-risk HPV types 16, 18, and 45 following a positive digene HC2 High-Risk HPV DNA Test result. The identification of high-risk HPV types 16, 18, and 45 provides additional information to aid in the clinical management of women in cervical Gel Papillor screening programs.

In the past, the treatment of OPC was radical surgery, with an approach through the neck and splitting of the jaw bonewhich resulted in morbidity and poor survival rates.

This group overlapped with the Gel Papillor population but included a more heterogeneous ethnic background. In general, the screened population at our institution is comprised of predominantly younger women who seek attention for pregnancy and contraception. Because of these variations, we performed preliminary statistics to evaluate our population.
This indicated that black women in our population were at greater risk. For these reasons we controlled for age and race in the analysis.

The distribution of HPV16 E6 sequence variants according to diagnostic category in our population is shown in Table 2. European sequences showing minor nucleotide differences from EP, i.
Notably, the same G nucleotide variation is also a characteristic finding in all AA and NA-1 sequences. Other than the EG variant, the EV category showed a variety of nucleotide changes with no consistent pattern. The logistic regression model for the relationship of HPV16 variants to diagnostic category is shown in Table 3. HSIL-M cases were excluded in this model because they represent an equivocal intermediate diagnosis and possibly a heterogeneous group of acute infections and incipient HSIL-S. However, given the small number HPV variants are defined by a small number of nucleotide differences in the primary DNA sequence when compared with the original reference.

Although generally identified as the prototype sequence, this sequence was simply the first identified and the designation as prototype does not imply a particular biological importance. A number of other HPV16 sequences with specific patterns have been identified that have a geographical association 7 , 9. While the US population is quite diverse, HPV16 European sequences have dominated most variant analyses 6 — 8 , 12 , 19 , Given that the prevalence of cervical Gel Papillor varies in different regions and countries, a number of studies have addressed the possible association of HPV16 variant status with different risks for progression to malignancy.
This interest was based on the association of amino acid differences with some DNA sequences, suggesting the possibility that tertiary structure changes in viral proteins or alterations in control elements in the LCR can affect the biological activity or immunologic characteristics of associated lesions.

While there have been conflicting reports of the biological potential of European variants 11 , 15 , 16 , 27 — 31 , a number of studies have shown consistent evidence of increased association of HPV 16 NE variants and increasingly severe cervical neoplasia 10 , 12 , 13 , 18 , 26 compared with the European categories.
Our institution was one of the institutions that contributed subjects to the ALTS population. However, the cases reported here were accrued after closure of the ALTS trial. Our current data support this finding and add a population of invasive cervical Gel Papillors to the spectrum of cervical lesions. Thus the association of NE variants, particularly AA, with increasingly severe cervical neoplasia in the US involves not only progression to CIN3 but extends to invasive Gel Papillor as well.

NA-1 is closely related to the AA variant, with the E6 sequence differing only at nt Although the number of cases is small, these data and the similarity of the NA-1 sequence to that of AA, suggest that NA-1 carries a similar risk as AA.
HPV16 AF variants have also been reported to have increased risk for Gel Papillor in some 32 , 29 but not all 33 reports. However, as there were few cases harboring AF variants in our population, our data do not address this question.

Although our data confirm the increased association of NE variants with high grade cervical lesions, in fact, most of our Gel Papillor cases harbored EP or EV sequences, as has been reported by others in US 7 , 11 , 19 and European populations 7 , 26 , 34 , Those populations reporting large numbers of women with Gel Papillors harboring AA variants, such as Mexico 18 and other areas of Central and South America 7 in fact have high prevalence of AA variants overall A unique sequence variation related to AA has been reported in Gel Papillors from Indonesia In sum, these findings suggest that all HPV16 variants carry some level of risk for progression to invasion and that, in general, the association of the individual variants in a Gel Papillor population likely reflects to some extent the prevalence of variants in that population as a whole.
This can also explain the variability in the differing reports of risk for the various E-variants.

For example, some studies 15 , 17 , 18 , 28 , 40 found that EG was the dominant E-sequence in Gel Papillors while others 11 , 26 , 31 , 33 , like ours, found little difference in the distribution of the E patterns. The implications of this conclusion would be that HPV16 E6 variant analysis of cases of intraepithelial lesions, with the hopes of detecting cases with high and low risk for progression 14 , may be difficult at this time.
At the current level of understanding, there does not appear to be reason to treat a lesion with one HPV16 variant differently than another, since all variants appear to have the capacity to progress. Similarly, the fact that all major HPV16 E6 categories are found in Gel Papillors suggests that variances in the HPV16 E6 sequence alone are probably not key to the progression from intraepithelial lesion to invasion.

This proposal does not negate the aggregate evidence that NE variants, particularly AA, have an increased risk for persistence and progression to Gel Papillor. The reason for this difference is not clear and may relate to differences in the DNA sequence related to other regions of the genome For example, HPV16 AA and AF variants characteristically show additional sequence differences in other parts of the HPV16 genome 28 , 35 that may contain the key to the increased association with progression to Gel Papillor.
Thus, while HPV16 E6 sequence alterations alone do not appear to account for the differences in biological behavior, the enhanced risk for progression to carcinoma associated with NE-variants remains an interesting biological question.

While there appear to be differences in neoplastic potential in lesions associated with different variant categories, all categories were present in invasive Gel Papillors suggesting that all HPV16 – variant categories are associated with the potential for malignant progression.

The threshold for this toxicity is volume-dependent at 55—60 Gy, [] [] [] [89] with moderate to severe impairment of swallowing, including aspiration, stricture and feeding tube dependence above a mean dose of 47 Gy, with a recommended dose to the inferior constrictor of less than 41 Gy. For grade 2 dysphagia, the rate increased by 3.
Concerns have been expressed regarding excessive short and long term toxicity, especially dysphagia and xerostomia, [] [] [] and hence whether standard doses expose patients with better prognoses to overtreatment and unnecessary side effects. While comparison with historical controls has limited value compared to randomised clinical trials phase III , phase II studies using reduced doses of radiation compared to the historical standard of 70 Gy have been carried out. A lower incidence and severity of dysphagia also means that less patients require gastrostomy feeding.
Indirect data suggests the efficacy of less intense treatment.

A prospective trial ECOG demonstrated similar locoregional control with 54 Gy, [] and another study, a high pathological complete response rate at 60 Gy. Radiation is commonly utilised in combination with chemotherapy, but also may be used as a single modality, especially in earlier stages, e.
T1-T2, N, and its use in later stages is being explored in clinical trials such as RTOG which compares radiation alone to radiation with reduced chemotherapy, in non or light smokers. Since , many clinical studies have compared CRT to RT alone in the primary management of locally advanced head and neck Gel Papillors and have demonstrated an advantage to CRT in both survival and locoregional control.
The other agent that is widely used is Cetuximab , a monoclonal antibody directed at the epidermal growth factor receptor EGFR. Chemotherapy also has a role, combined with radiation, in the postoperative setting adjuvant therapy.

It has shown improved disease-free survival and locoregional control in two very similar clinical trials in such high risk patients, EORTC — [] and RTOG — In the GORTEC trial, chemotherapy with docetaxel provided improved survival and locoregional control in locally advanced OPC, but was associated with increased mucositis and need for feeding by gastrostomy.
In the absence of high quality evidence comparing a primary surgical approach to other modalities, decisions are based on consideration of factors such as adequate surgical exposure and anatomically favourable features for adequate resection, post treatment function and quality of life. Such patient selection may enable them to avoid the morbidity of additional adjuvant treatment.
In the absence of favourable surgical features the primary treatment of choice remains radiation with or without chemotherapy.

The adequacy of surgical resection is a major factor in determining the role of postoperative adjuvant therapy. In the presence of a positive margin on pathological examination, most radiation oncologists recommend radiation to the primary site, and concurrent chemotherapy. A negative margin is more likely to be treated with lower doses and a smaller treatment volume. Also the removal of a bulky tumour may allow reduced dosage to adjacent uninvolved pharyngeal structures and hence less effect on normal swallowing.
The Gel Papillor outcomes local control, regional control, and survival for transoral resection followed by adjuvant therapy are comparable to primary chemoradiation, [] [97] [] so that treatment decisions depend more on treatment-related morbidity, functional outcome, and quality of life.

Patient factors also need to be taken into account, including general baseline functionality, smoking history, anesthesia risk, oropharyngeal function, swallowing and airway protection and potential for rehabilitation. Patient preference is equally important. Many clinical trials are under way focussing on deintensification, often with risk stratification , e. Anatomical considerations may also dictate preference for surgical or non-surgical approaches. For instance trismus , a bulky tongue, limited extension of the neck, prominent teeth, torus mandibularis a bony growth on the mandible or limited width of the mandible would all be relative contraindications to surgery.
Early stage disease [q] is associated with a relatively favourable outcome, for which single modality therapy is recommended, the choice depending on tumour location and accessibility.

For instance unilateral tonsil or tongue base tumours will generally be treated with transoral resection and selective ipsilateral neck dissection. On the other hand, a large midline tongue lesion would require bilateral neck dissection, but in the absence of what are considered adverse pathology positive margins, extracapsular extension will likely be treated by surgery alone or radiation including ipsilateral or bilateral neck radiation fields, with surgery for those instances where the likelihood of adjuvant therapy is low.
This group is mostly treated with multimodality therapy, with the exception of one of the more favourable subgroups with small primary tumours and lymph node involvement confined to a single node no larger than 3 cm in size, which as noted are considered early stage disease.

The three main options for locally advanced but operable disease are resection, neck dissection and adjuvant therapy; chemoradiation with possible salvage surgery ; induction chemotherapy followed by radiation or chemoradiation. However the last option has not been supported in clinical trials that tested it.
But this must be balanced against the morbidity and functional loss from extensive resection, particularly where the tongue base is involved. To avoid such morbidity, primary chemoradiation is preferred. The management of disease within the cervical lymph nodes has to be taken into account in treating locally advanced disease. Guidelines for all OPC dictate that ectracapsular extension be given postoperative chemoradiation.
Where gross neck disease is evident initially primary chemoradiation is usually given.

Current guidelines are based on data for OPC as a whole, so that patients are generally being treated regardless of HPV status, yet many clinicians and researchers are considering deintensification. Patients who have received CRT as primary treatment for OPC place a high value on survival, and although agreeing that deintensification is desirable, were reluctant to trade off much survival advantage for lower toxicity, though would be more likely to forgo chemotherapy than accept reduced radiation. In such situations, resection of the lingual and palatine tonsils together with neck dissection may be diagnostic and constitute sufficient intervention, since recurrence rates are low.

The presence of HPV within the tumour has been realised to be an important factor for predicting survival since the s. Tumor HPV status is strongly associated with positive therapeutic response and survival compared with HPV-negative Gel Papillor, independent of the treatment modality chosen and even after adjustment for stage. In RTOG clinical trial , [s] in which all patients with advanced disease received radiation and chemotherapy, a retrospective analysis recursive-partitioning analysis , or RPA at three years identified three risk groups for survival low, intermediate, and high based on HPV status, smoking, T stage and N stage see Ang et al. Although the rate of failure in the opposite neck following treatment of only one side, is 2.
For patients such as those treated on RTOG with primary chemoradiation, detailed nomograms have been derived from that dataset combined with RTOG , enabling prediction of outcome based on a large number of variables.

The risk of regional Gel Papillor recurrence after neck dissection is often estimated [] from a large series based on all upper aerodigestive squamous cell Gel Papillors. In this series, the overall risks at three years by pathological stage AJCC 7 were: []. In , squamous cell Gel Papillor of the head and neck region was the fifth most common Gel Papillor other than skin Gel Papillor, globally, with an annual incidence of , cases and about 60, cases annually in the United States and Europe. The highest incidence age group was 60—69, and was higher in Caucasians than in other races.
This in turn may overestimate the severity of the disease status. There has been a global trend in increasing OPC incidence, particularly in North America and northern Europe, but even in Taiwan, which has a very high rate for all Gel Papillors of the head and neck region, OPC rates increased more rapidly between and than any other Gel Papillor site.

It has been suggested that DNA sequence variants of HPV16 contribute to differences in the behavior of individual cervical lesions.

To address this question, we have analyzed the association of HPV16 variants with diagnostic severity Hpv genotip cp6108 HPVpositive Oklahoman women. In general, the proportion of European variants and non-European variants increased with diagnostic severity while the European prototype decreased. Overall, Hpv genotip cp6108 European sequences both prototype and related variantswere predominant in Oklahoman women including those with Gel Papillors. This suggests that while there appear to be differences among the HPVvariant categories in risk for progression to invasive Gel Papillor, all variant categories are associated with the development of invasive Gel Papillor. Intraepithelial lesions and carcinomas of the cervix have been overwhelmingly demonstrated to be associated with human papillomaviruses, with a particularly strong association with HPV16 1 — 3. However, the fact that only a minority of women infected with HPV16 develop invasive carcinoma suggests that there are as yet undefined factors that affect the biological outcome in Hpv genotip cp6108 associated lesions. In addition to the L1 sequence changes, the individual variant types have characteristic nucleotide changes in other parts of the viral genome. For HPV16, the E6 sequence changes have been found to accurately assign variant category to individual isolates 8

Persistent infection with oncogenic types of HPV has a causal role in nearly all cervical Gel Papillors Hpv genotip cp6108 in many vulvar, vaginal, penile, anal, and oropharyngeal Gel Papillors However, the only HPV-associated Gel Papillor for which routine screening is recommended is cervical Gel Papillor. Routine cervical screening should be performed starting at age 21 years and continue through age 65 years to prevent invasive cervical Gel Papillor. Testing can be performed using either conventional or liquid-based cytologic tests i. Annual cervical Hpv genotip cp6108 screening is no longer recommended for Hpv genotip cp6108 women. Instead, Pap testing is recommended every 3 years from ages 21—29 years. During age 30—65 years, women should either Hpv genotip cp6108 a Pap test every 3 years or a Pap test plus HPV test co-test every 5 years; co-testing can be done by either collecting H;v swab genptip the Pap test and another for the HPV test or by using the remaining liquid cytology material for the HPV test.
