Compared with previous findings in cervical cancer, our data indicate that carrying the DQA1*0102-DQB1*0602 haplotype gives an increased risk of developing CIN when infected with HPV-16, without influencing progression to cancer.
The study is planning to enroll male and female subjects affected by genital lesions, in particular to collect 200 scrapes/biopsies from women with normal ectocervical epithelium as well as with all different degrees of ectocervical lesions (from CIN 1/LSIL to cervical carcinoma).
In previous studies, the HLA class II haplotype HLA DRB1*0401-DQB1*0301 was shown to correlate with susceptibility to HPV infection, CIN and cervical cancer while DRB1*0101-DQB1*0501 indicated protection.
It would be important to study c-erbB-2 gene amplification and also gene expression in different CIN stages in order to determine its role and significance in cervical cancer.
There were only 7.2% (54 of 746) infected high-risk HPV types in the control, whereas 54.5% (six of 11) and 76.5% (52 of 68) were infected in the CIN and cervical cancer, respectively.
To evaluate selected HPV genotyping, viral load, and viral integration status as potential predictive markers for CIN progression, we performed HPV genotyping in formalin-fixed, paraffin-embedded cervical tissue with cervical carcinoma (29 cases) and CINs (CIN 1, 27 cases; CIN 2, 28 cases; CIN 3, 33 cases).
HPV DNA testing is a useful indicator in the management of patients with ASC-US and plays an important role in the evaluation of risk for CIN 2,3 and cervical cancer.
Among the HPV-negative patients, two (11.8%) had CIN 1, five (29.4%) CIN 2, nine (52.9%) CIN 3 and one patient (5.9%) had microinvasive cancer of the uterine cervix.
Abbott RealTime HR HPV was evaluated with 253 cervical specimens obtained from patients with CIN 3 and 340 specimens from patients with cervical cancer to determine clinical sensitivity of the test and the prevalence of types 16 and 18.
From a clinical point of view, testing for a broad spectrum of high-risk human papillomavirus (hrHPV) is only useful when a positive hrHPV test result is informative about the presence of high-grade cervical intraepithelial neoplasia or cervical cancer (CIN 2 or worse).Two hrHPV tests, i.e.
We conclude that this is the first paper to point out that integration of high-risk HPVs not only 16 and 18 but also 52 and 58 is correlated with high levels of oncogene transcripts from normal cervix, CIN to cervical cancer.
In two case-control studies, 30 participants did not have CIN, 18 had low-grade CIN (CIN1), 64 had CIN2,3, seven had cervical cancer and the diagnosis was undefined for 27 women.
The major concern in conservative treatment is to verify whether CIN eradication was complete, since incomplete excision is associated with an increased risk of cervical cancer.
From 85 published reports, which include 3,922 cases and 2,099 noncancerous control tissue samples, 63 differentially expressed miRNAs (DEmiRNAs) were identified in different stages of cervical cancer development (CIN 1-3 and CC).
