Beskrivelse
Inclusion Criteria:
- Patients with primary locally advanced rectal adenocarcinoma (0-18cm from the anal verge) confirmed by MSKCC pathologist and eligible to undergo chemoradiation and surgical resection at MSKCC.
- Written informed consent
- Age equal to or greater than 21 years
- Willing and able to undergo all study procedures
- Patients must have a planned surgical resection of the rectum
Exclusion Criteria:
- Patients younger than 21 years
- Pregnant and nursing women
- Contraindications for MRI (such as claustrophobia, pacemaker, non MR-compatible artificial heart valves, cochlear implants, surgical clips in the brain, metal fragments in eye)
- Estimated GFR (using Cockcroft formula Appendix 2) less than 30 ml/min/1.73m2 (FDA advises caution in using gadolinium-based contrast agents in patients with severe renal impairment).
- History of allergic reaction to MR contrast media
- Inability to give informed consent in person

|---|---|
|
Eksperimentel: 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.

|
Eksperimentel: 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.

Eksperimentel: 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.

Eksperimentel: 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.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Determine if the best imaging schedule for DCE is the same as for DWI
Tidsramme: 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.
