Rectal Neoplasms Clinical Trial
Official title:
Pilot Study of Gene Expression and FDG-PET/MR Biomarkers for Evaluation of Response to Neoadjuvant Therapy for Locally Advanced Rectal Cancer
This pilot clinical trial studies gene expression analysis and fludeoxyglucose F 18 (FDG) positron emission tomography (PET)/magnetic resonance imaging (MRI) in evaluating treatment response in patients with rectal cancer that has spread to nearby tissue or lymph nodes undergoing chemotherapy and radiation therapy before surgery. Studying samples of tissue in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and may also help doctors predict a patient's response to treatment before surgery. PET-MRI is a procedure that combines the pictures from a PET scan and an MRI scan. The combined scans give more detailed pictures of areas inside the body than either scan gives by itself. PET-MRI may help determine how well people respond to pre-surgery chemotherapy and radiation therapy and help the surgeon make the best plan for removal of the tumor.
