Active clinical trials for "Carcinoma in Situ"

Vulval cancer, while rare, has increased in incidence by 17% since the 1990s. It is strongly associated with age, thus this increasing trend is likely to continue with extended life expectancy. Vulval cancer is highly treatable when detected early. Women with chronic vulval conditions including lichen sclerosus, lichen planus and vulval intraepithelial neoplasia are at increased risk of developing vulval cancer. Most patients are in hospital follow-up, however regular vulval self-examination can pick up lesions earlier. There are no formalised methods of teaching self-examination and no evidence that it is acceptable to women. The main objective of this study is to pilot an intervention to promote and support vulval self-examination for women at increased risk of vulval cancer including those with lichen sclerosus, lichen planus and vulval intraepithelial neoplasia. Findings from this feasibility study will inform the design of a randomised trial comparing the interventions versus control with an embedded cost-effectiveness analysis.

This clinical trial studies mammography and targeted ultrasound with or without whole-breast ultrasound or contrast-enhanced magnetic resonance imaging (MRI) in finding out the extent of disease before surgery in patients with newly diagnosed breast cancer. New diagnostic imaging procedures, such as whole-breast ultrasound or contrast-enhanced MRI, may help find out how far breast cancer has spread. It is not yet known whether mammography and targeted ultrasound are more effective with or without whole-breast ultrasound or contrast-enhanced MRI in finding out how far breast cancer has spread.

The current study aims at answering the scientific question, whether exfoliated cells from STICs get transported into the uterine cavity via the fallopian tube, and whether it is possible to detect those cells in the lavage fluid from the uterine cavity and proximal fallopian tubes. To address this question, the investigators will study 20 lavage samples and their 20 corresponding STIC-positive tissue samples in women who opt for risk-reducing bilateral salpingo-oophorectomy (rrBSO) because of increased risk of high grade serous carcinoma of the pelvis (HGSC) (mostly carrying a BRCA mutation), without a history of tubal occlusion for sterilization. Women who opt to have the fallopian tubes removed but the ovaries preserved are eligible for the study too, as are women who opt for rrBSO plus hysterectomy.

This randomized phase II trial studies how well docosahexaenoic acid works in preventing recurrence in breast cancer survivors. Docosahexaenoic acid supplement may prevent recurrence in breast cancer survivors.

This randomized clinical trial studies home-based HPV or clinic-based Pap screening for cervical cancer. It is not yet known whether home-based screening is more effective, cost-effective, and/or acceptable than clinic-based screening for cervical cancer.

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 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.

RATIONALE: Diagnostic procedures, such as MRI, may help find ductal carcinoma in situ and find out how far the disease has spread. PURPOSE: This clinical trial is studying how well MRI works in assessing tumor size in women with ductal carcinoma in situ.

This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.

This study is to evaluate lot-lot consistency of Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli) .
