Inclusion Criteria:

• Patient must give study-specific informed consent on an IRB-approved consent prior to any research related procedures or study treatment.
• Patient must be at least 18 years at the time of consent Adenocarcinoma of the prostate with AJCC Clinical Stage T1to T3b disease with histological evaluation via biopsy or repeat biopsy within 12 months prior to registration. Refer to Appendix IV for clarification on study eligibility and AJCC stage group.
• Patients must undergo a pretreatment diagnostic MRI of the prostate on a 1.5T to 3T Tesla machine within 6 months prior to study registration.
• A focal IPT must be visible on MRI within the prostate and/or seminal vesicles and this MRI must be obtained within 6 months of planning CT scan.
• A biopsy of the dominant lesion is recommended but not required. If an ultrasound guided sextant biopsy was positive for prostatic adenocarcinoma in the area of the MRI identified intraprostatic lesion, this will be acceptable and another guided biopsy targeting the MRI identified disease will not be necessary.
• Patients with at least one of the following high-risk factors: cT3a-T3b OR Gleason 9-10 OR PSA > 30 OR more than 1 high-risk factors must be present: clinical stage of T3, Gleason score 8-10, or PSA 20 ng/ml or greater.
• Hemoglobin must be ≥ 10 g/ml within 4 months prior to registration.
• Zubrod performance status must be 0-1 within 4 months prior to registration.
• If patient has child-producing potential, they must be willing to use medically acceptable contraception during treatment and must be advised to use it for at least 1 year thereafter. This is not applicable if the patient is not sexually active or has had a vasectomy. Please document as such.
• Patients must be able to start treatment within 16 weeks of registration.

Exclusion Criteria:

• T4 prostate disease on CT, MRI, or physical exam.
• Patients unable to undergo MRI of the prostate.
• Patients with a greater than 25% change in prostate volume from the pretreatment MRI of the prostate demonstrating the IPT and the treatment planning MRI. Patients in this case must undergo a repeat diagnostic MRI on a 1.5T to 3.0T Tesla machine and an IPT must still be visible.
• IPT that is more than 75% of the prostate volume when measured on the CT simulation scan.
• Evidence of distant metastasis (M1).
• Patients with positive nodes on cross-sectional imaging.
• Previous prostate cancer local treatment including prostatectomy, hyperthermia, high intensity focused ultrasound, brachytherapy, external-beam radiation therapy, and/or cryotherapy.
• Prior pelvic radiation therapy.
• No prior myocardial infarction within the last 6 months, congestive heart failure, or end stage renal disease.
• Active inflammatory bowel disease (diverticulitis, Crohn's disease, ulcerative colitis) affecting the rectum.
• Bilateral hip replacement
• Prior intrapelvic surgery. This includes the following:Bladder surgery,Transrectal or rectal surgery other than prostate biopsy, Polypectomy or hemorrhoid removal or banding
• Prior transurethral resection of the prostate (TURP) or laser ablation for benign prostatic hyperplasia (BPH).
• Patients receiving continuous and current anticoagulation with warfarin sodium (Coumadin), heparin sodium, clopidogrel bisulfate (Plavix), dabigatran etexilate mesylate (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis), edoxaban (Savaysa), enoxaparin sodium (Lovenox), prasugrel (Effient), ticagrelor (Brilinta), aspirin/er dipyridamole (Aggrenox), or fondaparinux sodium (Arixtra).
• Patients with posterior or posterolateral extracapsular extension of prostate cancer. If this is present, it must resolve on diagnostic MRI after 2 to 3 months of neoadjuvant androgen deprivation therapy prior to enrollment. Refer to Appendix V for definition of extracapsular extension
