Brief Title: Immunoscore in Rectal Cancer
Official Title: A Study to Determine the Immunopheotype of Locally Advanced Rectal Adenocarcinoma and Its Correlation With the Efficacy of Neoadjuvant Chemoradiotherapy
Study ID: NCT02017509
Brief Summary: This is an observational study of tumor samples and MRI imaging in patients with colorectal cancers. A tumor sample, MRI scans, and treatment outcome data will be used for research purposes to see if it is possible to predict patients' response to treatment.
Detailed Description: The quality of the immune environment in colorectal cancer biopsy samples correlates with disease-free survival and overall survival more so than current staging conventions. This study will use a scoring system called 'immunoscore' to characterize the immune enviroment. Researchers hypothesize that the immunoscore will correlate with outcomes of colorectal patients treated with neoadjuvant chemoradiation.
