Active clinical trials for "Carcinoma in Situ"

This study will determine whether Synergo® RITE + MMC treatment is efficacious as second-line therapy for CIS NMIBC BCG-unresponsive patients with or without papillary NMIBC, through examination of the complete response rate (CRR) and disease-free duration for complete responders. The study will also explore progression-free survival time, bladder preservation rate, and overall survival time. The study will address an unmet need to identify a treatment effective in both ablating the disease and providing a prolonged disease-free period for patients. Ideally, the treatment will delay progression to invasive disease, thus preserving the bladder.

The purpose of this study is to test if an experimental drug called Durvalumab (Medi4736) given by intravenous (IV) infusion is effective in treating carcinoma in situ (CIS) of the bladder that no longer responds to Bacillus Calmette-Guérin (BCG) and to collect information on the safety of these drugs and whether they cause any side effects.

Currently, colonoscopy is the safest way to detect bowel tumors and polyps, since these can be biopsied and removed in one working process. If the size of adenomas is larger than 2 cm, resections are usually done in a hospital setting. For the resection of large adenomas, different approaches can be used. The so-called piecemeal resection is done with snares, to cut off parts of the adenoma piece by piece until the whole adenoma is resected. This technique is the standard therapy, but is not required for very large adenomas, which can often show cell alterations that indicate cancer. Therefore these adenomas should be resected in one piece. This is done by the so-called en-bloc resection. For this kind of therapy, different endoscopic knifes are use to cut off the adenoma as a whole. Both resection techniques are done usually by previous injection of saline or other liquids to elevate the lesion from its bottom tissue. Although the piecemeal resection of large adenoma is the standard therapy, it shows recurrence rates of 10 to 25%, which afford repeated therapies and follow up controls. En-bloc resections, though, are expected to have less recurrence rates but are much more complex to perform. They have higher complication rates especially in the West, where it has bee introduced only a couple of years ago. The data situation regarding safety and efficacy of both therapies is low. This study is the first one ever to compare piecemeal EMR and ESD in a randomized way. The study might have influence on the logistics of future adenoma processing and patient flow.

RATIONALE: Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. It is not yet known whether surgery is more effective with or without gefitinib in treating ductal carcinoma in situ. PURPOSE: This randomized phase II trial is studying how well gefitinib together with surgery works compared to surgery alone for the treatment of women with ductal carcinoma in situ of the breast.

This study evaluates the use of ABI-1968, a topical cream, in the treatment of anal precancerous lesions in adults with and without human immunodeficiency virus (HIV) infection

The purpose of this study is to investigate the non-inferiority of a topical Imiquimod therapy in patients with persistent CIN 2/3 when compared to standard therapy, i.e. conization A randomized, controlled, non-inferiority AGO-Austria trial

Analysis of women's medical records to understand the impact of previous changes to breast cancer screening (increase from one to two clinicians examining each woman's mammograms, and what proportion of women they recall for further tests)

To assess the role of different combinations of (oncoplastic) surgery and radiotherapy techniques as risk factors for moderate to severe fibrosis and for moderate to poor cosmetic outcome.

This phase II trial studies whether intermittent fasting works to improve outcomes in patients with stage I-III breast cancer receiving chemotherapy before surgery (neoadjuvant) with a body mass index >= 25. Intermittent fasting has been shown to elicit similar metabolic changes as calorie restriction such as reduction in blood glucose levels, improved insulin sensitivity, and reduction of tumor cell growth. Intermittent fasting may improve outcomes in patients with breast cancer

The purpose of this study is to examine the genetic material called microRNA of three types of specimens from women with breast cancer. The study also seeks to examine the effectiveness of using a new agent called oxytocin to increase the amount of nipple fluid that can be collected during surgery.
