OBJECTIVE To estimate the accuracy of colposcopy to identify cervical precancer in screening and diagnostic settings. METHODS As part of a larger clinical trial to evaluate the diagnostic accuracy of optical spectroscopy, we recruited 1,850 patients into a diagnostic or a screening group depending on their history of abnormal findings on Papanicolaou tests. Colposcopic examinations were perfo...

Background: With the implementation of primary high-risk human papillomavirus (hrHPV) screening in Netherlands, an increase was observed number unnecessary referrals (?Cervical Intraepithelial Neoplasia (CIN) 1) to colposcopy. We aimed investigate which alternative triage strategies safely reduce HPV-based cervical cancer programmes. Methods: Microsimulation model MISCAN used simulate unvaccina...

Infection with certain types of human papillomavirus (HPV) is a necessary event in the development of cervical carcinoma; however, not all women who become infected with HPV will progress to cancer. Much is known about the molecular influence of HPV E6 and E7 proteins on the malignant transformation. Little is known about the additional factors needed to drive the process. Quantitative real-tim...

To date, cancer of uterine cervix is still a leading cause of cancer-related deaths in women worldwide. The current methods (i.e., Pap smear and liquid-based cytology (LBC)) to screen for cervical cancer are time-consuming and dependent on the skill of the cytopathologist and thus are rather subjective. Therefore, this paper presents an intelligent computer vision system to assist pathologists ...

Cervical intraepithelial neoplasms The cervical intraepithelial neoplasms (CINs) are abnormalities of the squamous ectocervical epithelium. The first group consists of squamous intraepithelial lesions of low histological stage (LSIL) and includes flat condyloma and CIN I, while the second group consists of squamous intraepithelial lesions of high histological stage (HSIL) including CIN II and C...

OBJECTIVES Cervical screening guidelines now recommend repeat cotesting of patients aged 30 years and older having a human papillomavirus (HPV)-negative low-grade squamous intraepithelial lesion (LSIL) in 1 year as preferred management. Only limited follow-up data on patients with HPV-negative LSILs are available from routine US clinical practice settings. METHODS In total, 680 patients with ...

BACKGROUND The human papillomavirus (HPV) and its variants show wide geographical distribution and have been reported to cause cervical lesions. With cervical neoplasia as the leading cancer in Indian women, the aim of the present study was to evaluate the multiple infection HPV type distribution and variant genotypes in cervical samples from the coastal Karnataka region, India. MATERIALS AND...

OBJECTIVE To study the accuracy of self vaginal douching and collection for HPV types 16, 18, 31 and 33 in women visiting Thammasat Hospital for the explicit purpose of cervical screening. METHODS A pelvic examination and Pap smear were performed for all women who came for cervical screening. Specimens were also collected by self vaginal douching before cervical screening and sent to the cell...

INTRODUCTION The progression of human papillomavirus (HPV) infection in the anogenital tract has been associated with the involvement of cells with regulatory properties. Evidence has shown that glucocorticoid-induced tumor necrosis factor receptor (GITR) is an important surface molecule for the characterization of these cells and proposes that GITR ligand may constitute a rational treatment fo...

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 >...
