Filter by:Women who don't participate in Swedish cytology screening program are a minority of about 10%, but constitute the majority of those who acquire cervical cancer. Over 50 000 women in the Västra Götalandregion have abstained from participation in the program for at least 2 screening rounds (6 - 10 years, depending om age). We plan to test two promising strategies to increase participation. In a study of two different health policies women who have defaulted are randomised to receiving a telephone call from a midwife, receive an offer of a self-test for HPV or being included in a control group. This is an effectiveness study that should give an answer how participation could be increased and give the basis for a calculation of the costs involved, before decisions can be made about implementing either intervention.
The purpose of this study is to test the hypothesis that chloroquine will reduce the ability of ductal carcinoma in situ (DCIS) to survive and spread. Participants will receive either chloroquine standard dose (500mg/week) or chloroquine low dose (250mg/week) for 1 month prior to surgical removal of the tumor.
This randomized, double-blind, placebo-controlled, parallel arm study will assess the safety and the efficacy of RO5217790 on histologic resolution in participants with high grade CIN associated with HR-HPV infection. Participants will be randomized to receive 3 subcutaneous injections of either placebo or RO5217790 on Days 1, 8, and 15. Study assessments will be made at Baseline, at Month 3 and 6, and every 6 months thereafter for an overall of 2.5 years.
The purpose of this trial is to determine whether SWETZ (Straight Wire Excision of Transformation Zone) is a superior alternative to LLETZ cone (Large Loop Excision of Transformation Zone cone biopsy) in the management of pre-invasive endocervical disease. SWETZ is a new cone biopsy procedure performed with a straight wire electrode and it will be compared to LLETZ cone, which is performed with a large loop electrode.
Human Papilloma Virus (HPV) infections induce cervical intraepithelial neoplasia (CIN) of cervix. To reduce incidence of invasive tumor associated with high grade CIN lesions, the standard treatment is the conisation of cervix (surgical act). A local treatment with the antiviral and anti-proliferative cidofovir would preserve the cervix of young subjects and reduce obstetrical morbidity induced by the conisation. This clinical study is aimed at : 1. evaluating the tolerance and safety of a cidofovir gel directly applied on the cervix exhibiting high grade CIN lesions; 2. evaluating the pharmacokinetic (PK) profile of cidofovir after local application.
This study will test the efficacy and safety of different routes of administration of a DNA vaccine in patients with HPV16+ CIN2/3. Subjects will be enrolled in one of six treatment groups. Subjects enrolled in the first two groups will receive vaccination intradermally with a needle-free delivery device. Subjects enrolled in groups 3 and 4 will receive vaccination intramuscularly. Subjects enrolled in groups 5 and 6 will receive vaccine intralesionally.
This randomized phase II trial is studying 4-hydroxytamoxifen to see how well it works compared with tamoxifen citrate in treating women with newly diagnosed ductal breast carcinoma in situ. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. It is not yet known whether topical tamoxifen causes less damage to normal tissue than systemic tamoxifen in treating patients with ductal carcinoma in situ.
The occurance and clinical course of human papillomavirus (HPV)-induced lesions is largely determined by the nature of the cellular immune defense generated. Even tough both genital warts and vulvar intraepithelial neoplasia (VIN) are HPV-associated genital lesions they differ in their risk of malignant progression. Imiquimod (IMQ) is a topically applied Toll-like receptor (TLR) 7 agonist that has been approved for the treatment of superficial (pre-) carcinomas of the skin (basal cell carcinomas, actinic keratosis) and HPV-associated lesions (genital warts). It acts by activation of the immune system exerting anti-tumor and anti-viral properties. The aim of the study is to evaluate the mechanisms of IMQ treatment and to analyze the differences in HPV-affected and non affected tissue at cellular and molecular level as determined by immunofluorescence stainings and real time PCR, respectively.
The present primary therapy of cervical intraepithelial neoplasia (CIN) grade 3 and persistent CIN 2 represents conisation. Surgical treatment can cause perioperative (infection, bleeding in in 5-10%) and postoperative (increased risk of preterm labor) complications, as well as incomplete resections (20%) and risk of recurrence in 5-17%. Imiquimod is an immunomodulating drug, that has been reported to be effective in human papilloma virus-related disease, such as vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VAIN), and anal intraepithelial neoplasia (AIN). The present randomised, placebo controlled, double blind study evaluates the efficacy of a topical treatment with imiquimod for 16 weeks in 60 patients with histologically confirmed CIN 2/3.
The objectives are to evaluate the effectiveness of treatment of cervical intraepithelial neoplasia (CIN) by loop electrosurgical excision procedure using persistence of human papillomavirus (HPV) as outcome, and to perform a long-term follow-up on the ability of HPV testing, as compared to cytology, to predict recurrence of high-grade CIN.
