Brief Summary:
This phase I/II trial studies the side effects and best dose of stereotactic body radiation therapy while using intensity-modulated radiation therapy (IMRT) planning to help avoid radiation to normal tissue in patients with prostate cancer. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using small, high doses of radiation over several days and may cause less damage to normal tissue. This treatment schedule allows for a higher dose of radiation to be administered over a shorter overall treatment period in comparison to standard radiation therapy.

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate the incidence of genitourinary (GU) and gastrointestinal (GI) acute and late toxicity for patients treated with prostate stereotactic body radiotherapy (SBRT) with simultaneous integrative boost, urethral ring sparing, and enhanced prostate localization (magnetic resonance imaging [MRI\-computed tomography [CT] fusion).

II. To also evaluate the incidence of GU and GI acute and late toxicity for patients treated with prostate stereotactic body radiotherapy (SBRT) with a more conventional and uniformly delivered dose of 7.25 Gy/fraction to the prostate.

III. Disease-free survival: disease-free failure events include local progression, distant progression, biochemical failure as defined by the Radiation Therapy Oncology Group (RTOG) Phoenix definition, and death from any cause.

SECONDARY OBJECTIVES:

I. Evaluate patient quality of life (QOL) using the Expanded Prostate Cancer Index Composite 26 (EPIC-26) for evaluation of the QOL for up to 3 years after the completion of SBRT.

OUTLINE: Patients are assigned to 1 of 2 treatment arms. Patients unable to undergo MRI, whose MRI proves technically inadequate for delineating needed anatomic structures, or who decline to enroll on Arm A are assigned to Arm B.

ARM A: Patients undergo 5 fractions of moderate dose SBRT with simultaneous integrated boost (SIB) every other day for 10 days following urethral-sparing IMRT planning.

ARM B: Patients undergo 5 fractions of uniform dose SBRT every other day for 10 days following undergo urethral-sparing IMRT planning.

After completion of study treatment, patients are followed up at 4-6 weeks, at 4, 8, and 12 months, every 4 months for 1 year, every 6 months for 3 years, and then every 12 months thereafter.

Primary Outcome Measures :
  1. Incidence of GU and GI acute and late toxicity [ Time Frame: Up to 90 days ]
    Evaluation of delivering SBRT to the prostate using non-uniform dosing. We will evaluate the potential for any added grade 3 rectal toxicity with the use of a simultaneous integrated boost. A late adverse event will be defined as an adverse event occurring more than 90 days from the completion of RT.

  2. Disease-free survival as measured by the Phoenix definition [ Time Frame: Up to 60 months ]

Secondary Outcome Measures :
  1. Overall QOL, assessed using EPIC 26 quality of life assessment [ Time Frame: Up to 2 years ]
    Special emphasis on bowel, bladder, and erectile function.

  • Clinical stage N0, M0
  • Most recent prostate specific antigen (PSA) within 60 days of enrollment

Exclusion Criteria:

  • FOR ARM A: Inability to obtain a planning MRI or a planning MRI of sufficient quality to allow identification of the peripheral zone and urethra, or inability to adequately fuse the MRI to the planning CT scan
  • FOR BOTH ARM A AND ARM B:
