A modified, commercially available DNA-DNA in situ hybridization test that uses biotinylated probes for the identification of human papillomavirus (HPV) DNA types 6/11, 16/18, and 31/33/35 was evaluated. HPV DNA was detected in 314 of 787 (40%) histologically abnormal genital biopsy specimens by using the ViraType in situ assay (Life Technologies, Gaithersburg, Md.), in which the hybridization ...
BACKGROUND Cervical cancer and its precursor, high-grade cervical intraepithelial neoplasia (CIN2/3), are associated with persistent high-risk human papillomavirus (HPV) infection. HPV genotype prevalence varies with severity of cervical lesions, patient age and geographical location. The aim of this study was to investigate HPV genotypes prevalence and attribution according to the severity of ...
Gene promoter methylation may be used a potential biomarker for detecting solid tumor including cervical cancer. Here, we used methylation sensitive-high resolution melting (MS-HRM) analysis to detecting promoter methylation ratios of DAPK1, MGMT and RARB gene in patients with different cervical disease grade. The detection of gene promoter methylation was conducted in two hundred fifty patient...
BACKGROUND Intrahepatic cholangiocarcinomas develop through a multi-step carcinogenesis. Precancerous lesions are defined as biliary intraepithelial neoplasia. Sex determining region Y-box9 (Sox9) is required for the normal differentiation of the biliary tract. AIMS To evaluate the Sox9 expression in carcinogenesis and its correlation with clinicopathological features in intrahepatic cholangi...
To analyze Survivin, MMP-2, and MMP-9 expression in different types of cervical lesions and discuss their correlation and clinical significance. Patients with chronic cervicitis, cervical intraepithelial neoplasia, or cervical cancer in our hospital were collected. ELISA was applied to detect the level of Survivin, MMP-2 and MMP-9 in serum. Immunohistochemistry was used to measure Survivin, MMP...
This article reviews progress in chemopreventive drug development, especially data and concepts that are new since the 2002 AACR report on treatment and prevention of intraepithelial neoplasia. Molecular biomarker expressions involved in mechanisms of carcinogenesis and genetic progression models of intraepithelial neoplasia are discussed and analyzed for how they can inform mechanism-based, mo...
Mild and moderate dyskaryosis: can women be selected for colposcopy on the basis of social criteria?
OBJECTIVE To describe the distribution of cervical intraepithelial neoplasia grades among women with mild and moderate dyskaryosis after a single cervical smear and to determine whether social criteria could help identify women who are at increased risk of grade II or III disease. DESIGN Cross sectional analysis within a randomised prospective study. Subjects had a repeat smear, a colposcopic...
OBJECTIVE We conducted a systematic review to evaluate the characteristics of human papillomavirus testing, particularly Hybrid Capture 2, in follow-up evaluations after treatment for cervical intraepithelial neoplasia for the detection of residual or recurrent cervical intraepithelial neoplasia grade >/= 2. STUDY DESIGN Medline was searched for relevant studies that were published between 19...
The purpose of the present study was to assess the role of hedgehog signaling pathway in the carcinogenesis of eyelid skin and conjunctival epithelial malignant tumors. The study was conducted on specimens from 41 patients with cutaneous eyelid basal cell carcinoma, 22 with bulbar conjunctival squamous cell carcinoma, 12 with bulbar conjunctival intraepithelial neoplasia. Major molecules of Hed...
Using the Southern DNA hybridization technique, tissues from 17 cases of invasive carcinoma of the uterine cervix, including nine cases of squamous cell carcinoma, four cases of adenocarcinoma, one case of adenosquamous carcinoma, and three cases of undifferentiated carcinoma, were examined for the presence of human papillomavirus (HPV) DNA. None of the studied cases had histologically confirme...
