مقدمه: گزارش های وجود asc-us (atypical squamous cells of undetermined significance)، asc-h (atypical squamous cells- cannot exclude high-grade squamous intraepithelial lesion)، lsil (low-grade squamous intraepithelial lesion) و hsil (high-grade squamous intraepithelial lesion) در پاپ اسمیر از جمله گزارش هایی هستند که نیاز به پی گیری دارند. این مطالعه، با هدف تعیین فراوانی asc-us، asc-h، lsil و ...
Results HPV-HR (high-risk) was positive in 377 cases, HPV-LR (low-risk) was positive in 165 cases and in 35 cases no HPV typing was performed. The herpes virus type 2 infection was present in 2 cases. Cytology showed LSIL (low grade squamous intraepithelial lesion) in 329 cases and HSIL (high grade squamous intraepithelial lesion) in 189 cases. Histological examination revealed cervical intraep...
BACKGROUND Persistent infection with high-risk human papillomavirus (HPV) has been recognized as a major cause of cervical cancer. Distribution of HPV genotypes may differ according to the geographic region and the severity of the cervical lesion. Determining HPV genotypes' specific distribution is useful for HPV surveillance and control programs. However, little is known about the distribution...
BACKGROUND Cervical cancer is the second most common cancer and cause of cancer-related death for women worldwide. The aims of this study were to investigate the prevalence of cervical neoplasia and examine factors associated with high-grade cervical squamous intraepithelial lesions (HSIL) among women taking part in a cervical cancer screening program in Beijing. METHODS Women aged 25-65 year...
INTRODUCTION Anal squamous cell carcinoma is preceded by persistent infection with high-risk human papillomavirus (HPV) and the cancer precursor, high-grade squamous intraepithelial lesion (HSIL). Detection of specific HPV genotypes and HPV-related biomarkers may be an option for primary anal screening. However, more data on the natural history of HPV-related anal lesions are required. The outc...
BACKGROUND Human Papillomavirus (HPV) genotype distribution and co-infection occurrence was studied in cervical cytologic specimens from Murcia Region, (southeast Spain), to obtain information regarding the possible effect of the ongoing vaccination campaign against HPV16 and HPV18. METHODS A total of 458 cytologic specimens were obtained from two outpatient gynecological clinics. These inclu...
Cancer-derived matrix metalloproteinases (MMPs) are proposed to be essential for tumor stromal invasion and subsequent metastasis. To explore the role of MMPs in cancer progression, we examined the expression of various MMPs and tissue inhibitors of MMPs in precancerous and cancerous lesions of the uterine cervix. Immunohistochemical studies demonstrated that MMP-2 and MMP-9 were expressed in >...
Background: This research was accomplished to evaluate the IHC expression of p16 (ink4a) and CK17 in low grade cervical intraepithelial lesions (LSIL), high grade cervical intraepithelial lesions (HSIL) and invasive cervical carcinomas and to assess their correlation to HPV (16E6+18E6). Methods: The study...
Aim: To assess the clinical significance of hTERC amplification for cervical cancer screening detected by fluorescence in situ hybridization (FISH) and compare it with that of current screening methods within the same group. Methods: A total of one hundred and nine women were recruited in this study. All of them had liquid-based thin-prep cytologic test (TCT), human papillomavirus (HPV) DNA tes...
