This is a study to first establish feasibility of the study and then to register the treatment data of adult patients with a diagnosis of intermediate risk of prostate cancer presenting for definitive radiation treatment with either proton radiotherapy or Intensity Modulated Radiation Therapy (IMRT). The investigators propose to employ a hypofractionated strategy with our image guided treatment to further improve cancer control and decrease toxicity.

Primary Outcome Measures:
  • Number of Participants with Adverse Events [ Time Frame: Within 10 days ] [ Designated as safety issue: Yes ]
    Unable to tolerate 10% of treatments using proton radiotherapy. Unable to complete all treatments. Cannot be given treatment because anatomy is such that a dosimetrically satisfactory treatment plan cannot be devised.

  • Acute Toxicity [ Time Frame: Within 60 days of completion of radiotherapy ] [ Designated as safety issue: Yes ]
    Any grade 2 or higher GI or GU toxicity, other than GI or GU toxicity or any grade 3 or higher toxicity, other than GI or GU. In the feasibility phase of this trial, the observation window for acute toxicty is extended to 60 days from completion of radiotherapy, as a feasibility precaution.

Secondary Outcome Measures:
  • Late toxicity [ Time Frame: open-ended ] [ Designated as safety issue: Yes ]
    Any grade 2 or higher GI or GU toxicity or any grade 3 or higher toxicity, other than GI or GU which occurs beyond 60 days from completion of radiotherapy. Late toxicities will be graded according to the RTOG/EORTC late morbidity scoring system.

  • Biochemical/clinicalprogression-free survival [ Designated as safety issue: Yes ]
    The time from start of radiotherapy to either documented increase in PSA or clinical progression of disease (based on CT, MRI, or bone scan), death due to any cause or last patient contact alive.

Estimated Enrollment: 200
Study Start Date: August 2009
Estimated Study Completion Date: August 2014
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Interim Analysis of Acute Toxicty in first 11patients

Detailed Description:
This study will be done in two phases, first, a feasibility study and then a registration study. In the first, feasibility will be established using the primary objectives set below. The second phase will begin no earlier than 30 days after the last patient in the initial phase has completed treatment and once safety and feasibility has been verified. The secondary objectives will serve as the objectives for the second phase of the study.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients with non-metastatic adenocarcinoma of the prostate, presenting for definitive proton or photon radiotherapy of the prostate.

Inclusion Criteria:

  • Histoloically confirmed prostate adenocarcinoma within 365 days of registration.
  • Clinical stages T1a-T2c N0 M0 (AJCC Criteria 6th Ed). For any pelvic lymph node > 1.5 cm, biopsy of the lymph node is mandatory.
  • Histological evaluation of prostate biopsy with assignment of a Gleason score to the biopsy material; Gleason score must be in the range 2-7. Biopsy with >6 cores is strongly recommended. (The highest Gleason Score in any core reported on the pathology report will be used for determining inclusion.)
  • PSA values < 20ng/ml within 90 days prior to registration, and done either prior to prostate biopsy, or at least 21 days after prostate biopsy. If Gleason score is < 6, PSA value should be < 10 ng/ml.
  • Zubrod status 0-1 documented within 60 days of registration.
  • Androgen deprivation is at the discretion of the treating radiation oncologist.
  • Patients must give IRB approved study specific informed consent.
  • Patients must complete all required tests (History/Physical exam, Zubrod performance status, CBC, PSA, CT or MRI, Transrectal ultrasound with prostate core biopsies/Histological evaluation, Transrectal prostate fiducial marker placement, Bone scan, Bone x-ray or CT (if bone scan is equivocal), EPIC, EQ-5D, IPSS QOL instruments, Kilovoltage images, x-rays, fluoroscopy, 4D CT-scan, Prostate ultrasound, MRI diffusion, Calypso localization and tracking, Directed prostate biopsy, Local Pathology review, Physics consultation, Follow-Up Phone Call)
  • Patients must be able to start treatment within 56 days of registration.
  • Patients must be at least 18 years old.
  • Members of all races and ethnic groups are eligible for this trial.
