CT Virtual Proctoscopy for Staging and Volume Assessment for Rectal Cancer

This study has been completed.
Information provided by (Responsible Party):
University of Wisconsin, Madison Identifier:
First received: December 21, 2007
Last updated: August 26, 2011
Last verified: August 2011
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.
