Active clinical trials for "Carcinoma in Situ"

The purpose of this study is to determine whether the topical application of PEP005 is safe and effective for the treatment of cutaneous squamous cell carcinoma in situ (SCCIS, Bowen's disease).

A-007 is an investigational therapy which may be effective in the treatment of pre-cancerous cervical dysplasia (abnormal cell growth). The purpose of this study is to evaluate the safety and efficacy of A-007, when used to treat high-grade cervical dysplasia.

By this non-randomized prospective study, it's evaluated the outcome of patients underwent BCS for DCIS at whom an established score system to address adjuvant therapies have been prospectively applied, according to the wideness of free margins. Between March 2000 and April 2006, 224 patients were enrolled and followed within the study.

This phase II trial studies how well an early recovery after surgery protocol works in enhancing quality of life in participants with stage 0-IIIC gastric cancer undergoing surgery. The early recovery after surgery protocol may decrease pain and nausea, promote bowl function, decrease the number of days hospitalized, and improve a participant's ability to function normally after surgery.

Each year the Danish mammography-screening programme identifies a large number of patients with small non-palpable breast cancers or precancerous lesions. The majority of these patients are suitable for breast conserving surgery (BCS). The object of BCS is to remove the suspicious lesion completely without removing excess healthy breast tissue. To obtain this accurate lesion localization is essential. Until today the standard procedure in Denmark has been wire guided localization (WGL). Although the method has been utilized for a number of years it has several disadvantages. Often inaccurate lesion localization leads to incomplete lesion removal (positive margin) and subsequently reoperation. It can postpone the additional systemic treatment, offered after the operation. Other disadvantages are poor cosmetic outcome and inconvenient planning for the patient and the departments involved. The wire needs to be placed on the day of the operation, which decreases the flexibility of the procedure. The purpose of this study is to test a new method named radioactive seed localization (RSL). The method uses a small titanium seed containing radioactive iodine. It will be placed in the centre of the lesion, and during the operation, the surgeon can locate it with a handheld gamma probe. The seed can be placed a few days in advance, which means a more flexible course of treatment. The method seems promising with regards to reoperation rates, but it needs further testing. Hypothesis: RSL is a more accurate method, for localization of nonpalpable breast lesions, than WGL. Using RSL obtains, to a great extent, adequate negative margins, resulting in a reduced number of re-operations. The study will be performed as a randomised clinical trial, where the two methods will be compared to each other. The trial will be performed at the department of breast surgery at Rigshospitalet and include patients with nonpalpable breast lesions. Besides reoperation rates, duration of the surgical procedure and the amount of removed breast tissue will be compared.

The purpose of this study is to develop and validate a clinical decision support system based on automated algorithms. This system can use natural language processing to extract data from patients' endoscopic reports and pathological reports, identify patients' disease types and grades, and generate guidelines based follow-up or treatment recommendations

The investigators hypothesize that nipple-areola skin sparing mastectomy (NASSM) performed through an inframammary incision has a superior blood supply relative to a lateral oblique incision. Moreover, by minimizing complications and optimizing aesthetic outcomes, the investigators believe it will be associated with significantly higher patient reported outcome scores. The addition of information gained by use of intraoperative laser-assisted fluorescent angiography (measured with the Spy Elite imaging device) will reduce complication rates by directing intraoperative resection of ischemic tissue and limiting the volume of immediate implant placement in instances where real time imaging would suggest compromised perfusion. These quantifiable, objective measures will justify the use of NASSM and immediate implant placement coupled with intraoperative laser-assisted fluorescent angiography in prosthetic based breast reconstruction despite longer operative times.

Cervical cancer occurs commonly in HIV-infected women in South Africa. These women have poor response to treatment of cervical cancer precursors. This study will test whether giving the quadrivalent vaccine to women prior to surgical treatment of the cervical cancer precursor will improve outcomes. We hypothesize that pre-treatment HPV vaccine will result in a reduced occurrence or cervical cancer precursors in follow-up.

This study evaluates the use of topical ABI-1968 cream, in the treatment of cervical precancerous lesions in adult women.

The aim of this study was to compare two management options for CIN 2. This randomized clinical trial performed between 2003 and 2006. A series of 90 Brazilian women diagnosed as CIN2 were randomized into two groups: 1) 45 whose lesion was excised and,2) 45 women subjected to follow-up at 3-month intervals for 12 months.
