Information provided by (Responsible Party):
UNC Lineberger Comprehensive Cancer Center
  Purpose
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
Rectal Carcinoma

Study Type: Observational
Study Design: 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.

Further study details as provided by UNC Lineberger Comprehensive Cancer Center:

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

Secondary Outcome Measures:
  • Recurrence-free survival [ Time Frame: 5 years ]
  • Disease-specific survival [ Time Frame: 5 years ]
  • Overall survival [ Time Frame: 5 years ]

Enrollment: 8
Study Start Date: October 2012
Estimated Study Completion Date: October 2018
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
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.
