Filter by:The purpose of this study is to see how CT virtual proctoscopy compares to an ultrasound exam of the rectal area in determining the stage of rectal cancer for people recently diagnosed with rectal cancer. This study will also compare tumor volume before and after neoadjuvant therapy using CT virtual proctoscopy, with the ultrasound exam as a comparison. Neoadjuvant therapy consists of chemotherapy and radiation therapy. Neoadjuvant chemoradiation therapy is done before surgery to reduce the size of tumors.
The purpose of this study is to find out what happens to patients after they have surgery for rectal cancer. After being treated for rectal cancer, patients tell us that their bowel, bladder and sexual function have changed. We are trying to understand how these changes affect your quality of life. The research that we have now does not explain these changes or problems very well. The patients will be asked questions about bowel function, bladder function, sexual function, and quality of life so we can understand these changes better. This will help us take better care of our patients in the future, before and after their treatment for rectal cancer.
The aim of this controlled multicentric study is to assess rectal cancer surgery with sphincter preservation without pre operative mechanical bowel preparation
Monoclonal antibodies, such as pertuzumab and cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving pertuzumab together with cetuximab may kill more tumor cells. This phase I/II trial is studying the side effects and best dose of pertuzumab when given together with cetuximab and to see how well they work in treating patients with previously treated locally advanced or metastatic colorectal cancer
This study aims to compare the safty and technical accessibility of linear stapler and curved cutter stapler during mid to low rectal cancer surgery.
The goal of this clinical research study is to find the highest tolerable dose of bevacizumab (Avastin) and erlotinib hydrochloride (Tarceva) that can be given in combination with standard radiation therapy and capecitabine before surgery to patients with rectal cancer. The safety and effectiveness of this combination of therapies will also be studied. The goal of this Phase I trial was to determine the maximal tolerated dose (MTD) of concurrent capecitabine, bevacizumab and erlotinib with preoperative radiation therapy (RT) for rectal cancer. The trial completed as Phase I without progressing to the Phase II portion.
First-Line Bevacizumab and Chemotherapy in Metastatic Cancer of the Colon or Rectum
The purpose of this study is to determine the tissue kinetics of ertapenem in colonic tissue from three hours up to six hours (25% of dosing interval) after administration of ertapenem.
Pilot trial of pre-operative chemo/RT using Xeloda and external beam RT followed by definite surgery in patients with localized rectal CA
Anal sphincter preserving operations are now commonplace for both cancer and non-cancerous rectal diseases. However, this has not always been the case and this development has been facilitated by the invention of circular stapling instruments, which allow the bowel to be reconnected to the anal sphincters, where it would almost be impossible to do so manually. Nevertheless, some patients still require a permanent ostomy, as even with stapling devices ultra low joins of the bowel and sphincter muscles cannot always be performed by a conventional surgery. Therefore, a variety of alternative techniques have been proposed to avoid a permanent ostomy, but these have not become widespread due to the technical difficulty in performing them, their failure to completely eradicate rectal disease, and the damage they inflict upon the anal sphincters resulting in poor bowel function after surgery. The ideal ultra low sphincter preserving operation should remove the rectal disease entirely, allow the small or large bowel to be safely joined to the anal sphincters under direct vision, and retain the sphincter mechanism in its entirety. We propose such a technique that we term the APPEAR procedure, which approaches the lower third of the rectum via an incision between the scrotum or vagina, and the anal sphincters. This procedure preserves sphincter integrity, and allows either a stapled or manual join of the bowel to the sphincter mechanism, under direct vision. This trial is being conducted as a pilot study, with the procedure only offered to patients for whom a conventional sphincter saving procedure was technically impossible, or contraindicated.
