Filter by: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.
RATIONALE: Studying genes in samples of blood and/or tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at blood and/or tumor tissue samples from patients with ductal carcinoma in situ and blood samples from healthy volunteers.
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.
The purpose of this study is to investigate the difference in late radiation morbidity between hypofractionated and standard fractionated breast irradiation given to women operated with breast conservation for early breast cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether whole-breast radiation therapy is more effective when given with or without additional radiation therapy to the tumor in treating patients with ductal carcinoma in situ. PURPOSE: This randomized phase III trial is studying breast-conserving surgery followed by whole-breast radiation therapy to see how well it works when given with or without additional radiation therapy to the tumor in treating women with ductal carcinoma in situ.
