Advanced MR Imaging for Early Biologic Tumor Changes to Neoadjuvant Chemoradiation Treatment for Rectal Cancer

June 21, 2017 updated by: Memorial Sloan Kettering Cancer Center

Pilot Study of Advanced MR Imaging for Early Biologic Tumor Changes to Neoadjuvant Chemoradiation Treatment for Rectal Cancer

The purpose of this study is to see whether three new types of MRI techniques used during magnetic resonance imaging (MRI) of the pelvis to look at rectal cancer can help doctors to tell if the tumor is getting better in response to the radiation and/or chemotherapy treatments.

Detailed Description

This is a pilot study of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI, aka perfusion MRI) and diffusion-weighted MRI (DWI-MRI), herein referred to in combination as advanced MRI (aMRI) in the investigation of early tumor response to standard multi-dose, fractionated external beam radiotherapy (EBRT) of the pelvis given in the neoadjuvant setting concurrent with chemotherapy as well as induction chemotherapy prior to chemoradiotherapy or consolidation chemotherapy after chemoradiotherapy for primary rectal adenocarcinoma. This protocol aims to expand upon the growing body of knowledge concerning early changes in tumor neovascularity and cellular density as a potential biomarker of therapy efficacy. It further aims to address the trend towards more refined treatment stratification for lower risk tumors to avoid morbidity from potentially unnecessary radiation, chemotherapy or even radical surgery, by assessing the earliest changes that occur in microvasculature and perfusion and diffusion of water during this treatment to see if these can be predictive of long-term efficacy of therapy.

Description

Inclusion Criteria:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 1 A
The patients will undergo the standard pre chemoradiation MRI scan, followed by a repeat research scan 24 hours (+/- 6 hours) after their first radiation treatment. Then they will get another research MRI scan during the second week (+/- 5 days) of radiation. Finally they will get a standard post chemoradiation MRI scan prior to surgery.
Procedure: Advanced MR Imaging
Experimental: 1 B
The patient will undergo the standard pre chemoradiation MRI scan, followed by a repeat research scan 48 hours (+/- 6 hours) after their first radiation treatment. Then they will get another research MRI scan during the third week (+/- 5 days) of radiation. Finally they will get a standard post chemoradiation MRI scan prior to surgery.
Procedure: Advanced MR Imaging
Experimental: 1 C
The patient will undergo the standard pre chemoradiation MRI scan, followed by a repeat research scan 72 hours (+/- 6 hours) after their first radiation treatment. Then they will get another research MRI scan during the fourth week (+/- 5 days) of radiation. Finally they will get a standard post chemoradiation MRI scan prior to surgery.
Procedure: Advanced MR Imaging
Experimental: 2
The last patient patients that will undergo a standard pre-chemoradiation MRI scan, followed by a repeat research scan either 24, 48 or 72 hours (+/- 6 hours) after their first radiation treatment. Then they will get another research MRI scan during the second, third or fourth week (+/- 5 days) of radiation. Finally they will get a standard post chemoradiation MRI scan prior to surgery.
Procedure: Advanced MR Imaging

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
determine the best MR imaging schedule
Time Frame: 3 years
of early and midterm imaging times using DWI-MRI which will distinguish between near complete (90-99%)/complete pathology and clinical responders and partial/non-responders
3 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Determine if the best imaging schedule for DCE is the same as for DWI
Time Frame: 3 years
The analysis plan will be identical to the one for the primary endpoint: six change measures will be computed for each DCE-MRI parameter (parameters Ktrans, Ve, kep, AUC 90, AUC 180) and each of these change measures will be evaluated as a predictor using the reference standard nCR/CR. ROC curves and the area under them will be estimated and used to rank the predictors.
