In Singapore, the current cervical cancer screening uptake among women in Singapore has remained at low 50% since its introduction in 2004. It has been widely reported that under-screened women have the highest risk of cervical cancer. Self-sampling HPV DNA screening may be a solution to the low uptake rates of local women, particularly among the under-screened population in Singapore. Self-sampling comprises women using a swab to obtain samples from their vagina. In this study, we are comparing the sensitivity of detecting HPV positive women using HPV DNA test with self-sampling using flocked swab with the current physician sampling method. We also aim to determine acceptability of self-sampling HPV DNA test using flocked swab in cervical cancer screening. Designed as a feasibility study, it will comprise a prospective study of 300 women attending clinics in National University Hospital (NUH) and National Cancer Institute Singapore (NCIS).
HPV-303 is a prospective, randomized, double-blind, placebo-controlled phase 3 study of VGX-3100 delivered intramuscularly (IM) followed by electroporation (EP) delivered with CELLECTRA™ 5PSP in adult women with histologically confirmed high-grade squamous intraepithelial lesions (HSIL) (cervical intraepithelial neoplasia grade 2 [CIN2] or grade 3 [CIN3]) of the cervix, associated with HPV-16 and/or HPV-18.
This study evaluates the use of ABI-1968, a topical cream, in the treatment of cervical precancerous lesions in females without human immunodeficiency virus (HIV) infection.
The purpose of this study is to develop a low coherence interferometry (LCI) endoscopic probe that can examine the cervix for evidence of cervical dysplasia. The device will make optical measurements of the cervix to determine: 1. the difference between two different types of cervical cells: ectocervical cells and endocervical cells. Cervical dysplasia is most likely to occur at the junction between these two types of cells. 2. features of individual cervical cells that indicate whether the cell is normal or abnormal (cervical dysplasia).
The multimodal imaging technology, OCT-AFI, will be used to image sites on the cervix, the endocervical canal and vulva. The imaging probe is small enough, it can be inserted into the endocervical canal for imaging. The probe can also be placed in a conformable holder that can be shaped to conform the the folds of the vulva for vulvar imaging. The resultant images will be compared to histology images. The objectives are to determine 1. feasibility of the technology in imaging vulva and its capability in detecting vulvar intraepithelial neoplasias 2. feasibility in imaging cervix from endocervical canal to transformation zone to ectocervix 3. if combined OCT with AFI increases the sensitivity of detecting high grade lesions in the cervix compared to just AFI alone (previous work was AFI alone).
This study evaluates the use of topical ABI-1968 cream, in the treatment of cervical precancerous lesions in adult women.
HPV-301 is a prospective, randomized, double-blind, placebo controlled Phase 3 study to determine the efficacy, safety, and tolerability of VGX-3100 administered by intramuscular (IM) injection followed by electroporation (EP) delivered with CELLECTRA™ 5PSP in adult women with histologically confirmed cervical high grade squamous intraepithelial lesion (HSIL) (cervical intraepithelial neoplasia grade 2 [CIN2] or grade 3 [CIN3]) associated with human papillomavirus (HPV) 16 and/or HPV-18.
Endocervix (cervical canal) is the cavity of the cervix and connects the external os with the internal os. It is fusiform in shape and has posterior and anterior oblique longitudinal ridges, the plicae palmatae. These are not exactly apposed but inter-lock like a zipper so that the canal is kept closed. The original squamous epithelium is clearly identified as a smooth, usually featureless covering of the cervix; its uniform pink color contrasts with the redness of the original columnar epithelium. It joins the latter at the original squamocolumnar junction. Many clinicians encounter cervical lesions that may or may not be associated with cytologic abnormalities. Such abnormalities as ectropion, Nabothian cysts, and small cervical polyps are quite benign and need not generate concern for patient or clinician, whereas others, including those associated with a history of exposure to diethylstilbestrol, cervical inflammation, abnormal cervical cytology, and postcoital bleeding, should prompt additional evaluation. Further, in some patients, the cervix may be difficult to visualize. Several useful clinical suggestions for the optimal examination of the cervix are presented.
Almost half of all women will develop an HPV infection in their lifetime. While most infections are naturally asymptomatic or cleared by the immune system, some persist and can lead to the development of cervical, vulvar, or anal lesions and eventually cancer. Screening regimens for these lesions are currently only in place for the cervix through regular Pap tests. These Pap tests usually involve an examination of the vulva -however, no screening procedures exist for anal cancer for women. Several studies have suggested that women with existing gynecological lesions are more likely to develop anal lesions and anal cancer. Here the investigators propose a multi-center study which seeks to screen for and treat anal cancer in women over the age of 40 with vulvar lesions and a stable immune system. The investigators will achieve this through performing anal Pap smears on eligible women and conducting High Resolution Anoscopy (HRA) and appropriate treatment procedures on those with abnormal anal cells. With enough evidence, there may be an indication to establish regular anal cancer screening measures in this potentially underserved population. Hypothesis: The investigators hypothesize that at least 40% of women with vulvar cancer or VIN2/3 will have abnormal anal cytology. 35% of the population will be hrHPV DNA positive and 11% will additionally have AIN2/3. This prospective study may lay the groundwork for routine anal screening regimens in Ontario and help shift health policy to treat this population.
