Brief Summary:
This is a single arm, single center pilot study of 40 patients with uT3N0 or uT1-3N+ rectal cancer receiving pre-operative chemoradiation. Subjects will undergo PET/MRI scans before and after surgery.

Condition or disease
Rectal Carcinoma

Detailed Description:
The primary purpose of this study is to determine the negative predictive value of PET/MRI for determining pathological complete response from neoadjuvant chemoradiation.

Study Type : Observational
Actual Enrollment : 8 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: PET/MRI as a Predictor for Response to Preoperative Radiation Therapy and Chemotherapy in Resectable Rectal Cancer: a Pilot Study.
Study Start Date : October 2012
Actual Primary Completion Date : August 2014
Estimated Study Completion Date : October 2019

Primary Outcome Measures :
  1. Negative post-chemoradiation PET/MRI scan, as correlated with surgical pathology [ Time Frame: 4-8 weeks post-chemoradiation ]

Secondary Outcome Measures :
  1. Recurrence-free survival [ Time Frame: 5 years ]
  2. Disease-specific survival [ Time Frame: 5 years ]
  3. Overall survival [ Time Frame: 5 years ]
