Radiotherapy to the Prostate and Dominant Intra-Prostatic Lesion (DIL)
Prostate Cancer
About this trial
This is an interventional treatment trial for Prostate Cancer focused on measuring 17-407, Intermediate Risk Prostate Cancer, DIL, Dominant Intra-Prostatic Lesion
Eligibility Criteria
Inclusion Criteria:
Intermediate risk prostate cancer patients will be eligible for this study. Risk groups will be assigned as per NCCN guidelines. Intermediate risk patients will be defined as:
- PSA 10-20 ng/ml or
- Gleason score = 7 or
- Clinical stage T2b/T2c
Additionally, patients will be required to meet the following criteria:
- Age ≥ 18
- KPS ≥ 80
- Prostate size ≤ 60cc
- Presence of a prostatic lesion with maximum dimension of >/= 0.5cm and no more than two additional disease foci, each with a maximum dimension less than that of the dominant lesion.
- International Prostrate Symptom Score ≤ 15
- Subjects must fill out the standard MRI screening form and satisfy all MRI screening criteria
Exclusion Criteria:
- Prior androgen deprivation therapy for prostate cancer
- Evidence of metastatic disease on bone scan or MRI/CT
- MRI ineligibility due to the presence of a cardiac pacemaker, defibrillator or other implanted metallic or electronic device which is considered MR unsafe, severe claustrophobia or inability to lie flat for the duration of the study, etc.
- Metallic hip implant, metallic implant or device in the pelvis that might distort the local magnetic field and compromise quality of MP-MRI.
- Lateral pelvic separation greater than 50 cm and/or anterior-posterior separation greater than 35 cm which are incompatible with MRCAT reconstruction
- Contra-indications to receiving gadolinium contrast
- KPS < 80
- Pelvic MRI or CT (MRI preferred) evidence of radiographic T3, T4 or N1 disease.
- Prior history of transurethral resection of the prostate
- Prior history of chronic prostatitis
- Prior history of urethral stricture
- Prior history of pelvic irradiation
- History of inflammatory bowel disease

Arms of the Study
Arm 1
Experimental
MR Image Guided, Intensity-Modulated Radiotherapy
Patients enrolled in this study will undergo MR-based, image-guided, intensity-modulated radiotherapy using similar equipment, techniques, and treatment-planning procedures as currently practiced at MSKCC.
