Filter by: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.
Cidofovir could be an effective drug for the treatment of Anal Intraepithelial Neoplasia(AIN).
The purpose of this trial is to evaluate if Straight Wire Excision of the Transformation Zone (SWETZ) is superior to (Large Loop Excision of the Transformation Zone) LLETZ cone in reducing the incomplete excision of disease.
Objective: Determine the genotypes and risk factors associated with human papilloma virus infection in Mexican women. Methods: It was a cross-sectional study of women attended at the Materno-Perinatal Hospital "Mónica Pretelini" and the Medical Research Center (CICMED), who were asked to complete a risk factor questionnaire and submitted to colposcopy to identify SIL. Cervical swab samples were obtained to perform linear array HPV genotyping test (Roche®, Mannheim, Germany).
The objective of the study is to assess, in a phase 1/2 study, the safety and efficacy of this synthetic vaccine SLP-HPV-01® in HIV+ men with CD4 counts > 350 x 10E6/l and HPV16-induced intra-anal high-grade AIN (grade 2-3) that failed on, or recurred after previous treatment.
The aim of the present study： 1. To investigate the diagnosing value of pCLE for early esophageal squamous neoplasia. 2. To assess the detection rate of early esophageal squamous neoplasia by virtual chromoendoscopy
This randomized phase III trial studies metformin hydrochloride to see how well it works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.
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.
This pilot clinical trial studies the side effects of calcitriol in preventing lung cancer in high risk patients. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of calcitriol may keep cancer from forming in patients with high risk for lung cancer.
Phase I, Open-Label Study of the Safety, Tolerability, and Immunogenicity of a Three Dose Regimen of Escalating Doses of PEK Fusion Protein Vaccine in Women with LSIL or HSIL. PEK fusion protein vaccine (PEK + GPI-0100) is safe and well tolerated in patients with low-grade squamous intraepithelial lesions (LSIL) or high grade squamous intraepithelial lesions (HSIL) of the cervix and induces a measurable immune response.
