Filter by:Cervical conization is done for pre-cancer disease. The procedure is performed with local anesthesia and general anesthesia. Local anesthesia is given by paracervical block, and several different local anesthetics is being used including bupivacaine with and without adrenaline. Adrenaline might reduce local bleeding and reduce toxicity of bupivacaine by reducing absorption, but might affect cardiovascular function. This study will examine this effect.
This phase I research protocol is designed to assess immunogenicity and clinical endpoints in patients with human papillomavirus (HPV) 16 cervical intraepithelial neoplasia (CIN)2/3. The protocol tests the use of artesunate in suppository formulation applied intravaginally in patients with cervical dysplasia (CIN2/3). The primary endpoint is to determine and evaluate the safety, tolerability, and feasibility of intravaginal administration of artesunate in health women with CIN2/3.
This randomized trial studies transdermal or oral telapristone acetate in treating patients undergoing surgery to remove the breast (mastectomy). Telapristone acetate may help prevent breast cancer from forming in premenopausal women. Giving telapristone acetate transdermally may be safer and have fewer side effects than oral administration.
The study will examine the effect of aminolaevulinic acid (ALA) photodynamic therapy (PDT) of cervical precancerous lesions in women.
The clinical trial is part of a larger study to evaluate the safety and efficacy of screening techniques for cervical cancer among HIV-infected women. The investigators randomized women to undergo screening with Visual Inspection with Acetic Acid (VIA) or Visual Inspection with Lugol's Iodine (VILI), along with a colposcopy. All outcome and treatment decisions were based on the colposcopy exam done at the study visit. The investigators then compared outcomes between the two groups to assess the test characteristics of both VIA and VILI.
This pilot/feasibility trial seeks to explore whether an acute bout of negative energy balance prior to surgery affects biomarkers of neoplasia. Forty overweight or obese postmenopausal women diagnosed with ductal carcinoma in situ (DCIS) or early stage breast cancer (Stage I or II) who elect mastectomy or lumpectomy will be randomly assigned to 1-of-2 study arms: 1) an Attention Control Group that receives instruction on dietary approaches to correct nutritional deficiencies and progressive resistance training (PRT) that targets the arm ipsilateral to the affected breast; or 2) an Experimental Group that will receive PRT and guidance to correct nutritional deficiencies plus an intensive intervention to promote a 1.5-2 pound/week weight loss through diet, exercise, and behavior modification. This study will explore and contrast changes in body mass index (BMI) observed from enrollment to the time of surgery in the experimental vs. attention control arms, and also monitor changes in energy intake and physical activity. These changes will be studied in relation to the following endpoints: a) changes in select circulating biomarkers and gene expression related to cancer progression, hormonal status, inflammation and other energy-related factors; b) rates of tumor proliferation and apoptosis; c) tumor markers, e.g., insulin receptor, Vascular Epithelial Growth Factor (VEGF), Nuclear Factor kappa beta (NFkB), and phosphoproteins associated with the Convergence of Hormones, Inflammation and Energy-Rated Factors (CHIEF) pathway; and d) functional and health-related outcomes. Because both tumor tissue and blood will be examined from pre-to-post-intervention, this study will provide exciting new data that can elucidate pathways by which energy balance affects breast cancer progression. Although longer term weight loss is recommended for overweight and obese breast cancer survivors, it is not known whether placing the body in a state of negative energy balance will have a favorable impact on the tumor. If beneficial changes in tumor biology and the host environment occur with short-term, pre-surgical weight loss, this study provides proof of concept that weight loss may offer an acceptable and complementary treatment option that could be combined with standard therapies.
The protocol aims at demonstrating the technical feasibility and safety of doing endomicroscopic imaging (both probe-based confocal laser endomicroscopy (pCLE) and needle-based confocal laser endomicroscopy, nCLE) during colposcopy, hysteroscopy, and surgical procedures (open surgery and laparoscopic robot assisted or not) to examine all pelvic tissues including cervix, uterus, adnexia, peritoneum, normal and pathologic aspect.
This is a pilot study to test the short-term effectiveness of an alternative treatment approach for precancerous cells of the cervix. The study will also explore whether this new treatment is feasible to perform and if it is acceptable to patients.
The aim of the project is to compare NBI endoscopy and standard endoscopic method using white light and evaluate accuracy both methods in early detection and diagnosis hypopharyngeal and laryngeal precancerous and cancerous lesions. A higher contrast between the mucosal epithelium and blood vessels is achieved in NBI endoscopy using filtered light comparing to white light observations. This allows detection of small mucosal changes, few millimetres in diameter, which are not observable using white light. The second aim in patients with squamous cell carcinoma of the upper aerodigestive tract is to compare extension of mucosal lesions by evaluation of NBI endoscopy and white light endoscopy, which is crucial for perform targeted biopsy and for determination of resection margins in cancer surgery. The investigators expect that dysplastic changes of mucosa or early laryngeal cancerous lesions are detected in white light endoscopy rarely. In case our hypothesis is confirmed, frequency of precancerous and early cancerous lesions of hypopharynx and larynx is more common in patients with non-specific symptoms of laryngeal and pharyngeal diseases.
The purpose of this study is to evaluate the therapeutic efficacy of interferon alfa 2b and topical mitomycin C in patients with diagnosis of conjunctival-corneal intraepithelial neoplasia.
