Active clinical trials for "Carcinoma in Situ"

RATIONALE: Collecting samples of blood and tissue from patients with cancer to study in the laboratory may help doctors learn how fluvastatin effects biomarkers related to breast cancer. PURPOSE: This randomized phase II trial is studying how fluvastatin effects biomarkers in women undergoing surgery for ductal carcinoma in situ or stage I breast cancer.

RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Giving radiofrequency ablation before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This clinical trial is studying how well radiofrequency ablation followed by surgery works in treating patients with early invasive breast cancer or ductal carcinoma in situ.

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.

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.

Human papillomavirus(HPV) infect epithelial cells and have the capacity to stimulate cell abnormal hyperplasia, especially by those high-risk HPV types. HPV vaccine primarily targeting HPV6/11/16/18 has been available and makes it possible to prevent cervical cancer. However, a large population was left unvaccinated, specifically for those aged ones. In clinic, patients harboring high-risk HPV is quite prevalent in China or other developing nations. Removing the virus and prevention of malignant transformation is required. Mild local Hyperthermia with a certain temperature range has been successfully used in the treatment of some diseases. It has been utilised in the treatment of some neoplasm, fungal and HPV infections. Investigators' study found that local hyperthermia at 44°C could cleared HPV in more than half of the patients with plantar warts. Investigators also note the fact that in patients with multiple lesions, the clearance of the target lesion is commonly followed by clearance of other distant lesions, a phenomenon suggesting that local hyperthermia could aid in establishing a specific immune response to eliminate HPV.So the purpose of the study is to evaluation local hyperthermia in the treatment of cervical intraepithelial neoplasias grade I and II after 3 months, with positive high-risk type HPVs, and patients with positive testing for high risk HPVs. Appropriate control arms were designed for different conditions.

Trichloroacetic acid 85% =TCA is an investigational device intended to achieve a complete histologic remission in individuals with cervical intraepithelial neoplasia (CIN) grade 1/2. The device system is to be used only in accordance with the approved Investigational Plan on subjects, who have given written informed consent. High remission and regression rates are expected after a single topical treatment with 85% TCA. After a single topical treatment with 85% TCA for CIN 1-2 (Expected 70% or higher; null hypothesis: not higher than 55%). Regression is defined as improvement from high grade lesion (CIN 2) at baseline to low grade lesion (CIN 1) after TCA treatment. Regression from CIN 1 normal squamous epithelium after the TCA treatment is equal to remission and will be counted as a remission in combined analysis. Remission is defined as complete histologic remission of CIN back to normal squamous epithelium after the TCA treatment, i.e., no cervical dysplasia is detectable by histology or cytology after the TCA treatment. Type-specific HPV Clearance is defined as disappearance of the HPV type detected at screening.

Women who are diagnosed with CIN2 and who have a pregnancy wish are followed up 6 months after the diagnosis with new examinations. The regression rate is based solely on the woman's own ability to clear the cervical lesions. The use of condoms has shown a relatively good protective effect against Human Papillomavirus (HPV) infection. It has furthermore been indicated that condoms increase the regression rate of cervical lesions. The hypothesis of this study is that the regression rate of cervical intraepithelial neoplasia grade 2 (CIN2) increases when condoms are used consistently in the follow-up period of 6 months.

The primary objective of this study is to evaluate the incidence of vulva dysplasia recurrence within 12 months of treatment with Carbon Dioxide (CO2) laser ablation or ultrasonic aspiration.

This study is a phase II, single arm, controlled, open label internal pilot.

This is a Phase II/Phase III study of intravesical AD 32 (valrubicin) in patients with carcinoma in situ (CIS) who have been previously treated with intravesical Bacillus Calmette-Guerin (BCG) for CIS and in whom recurrence or failure has occurred after multiple courses of intravesical treatment.
