Rectal Cancer Clinical Trial
Official title:
Study of the Value of the PET/CT in Evaluating the Response of Distal Rectal Cancer to Neoadjuvant Chemoradiation Therapy
Preoperative chemoradiation therapy is the preferred initial treatment option for distal rectal cancers. However, assessing tumor response to preoperative chemoradiation therapy remains a challenge to the colorectal surgeon, especially when determining if there is a complete response, observed in more than 10% of cases. The purpose of this study is to evaluate the use of the PET/CT in assessing distal rectal tumor response to preoperative chemoradiation therapy.
