Brief Summary:
The first technology is called high dose rate brachytherapy. Brachytherapy is sometimes called internal radiation therapy. High dose rate brachytherapy is a procedure that involves temporarily placing radioactive material inside the patient's body for about 10-20 minutes. Then, the remainder of the radiation treatment will be given over a 3 week period using stereotactic body radiation therapy (SBRT). SBRT is a novel treatment modality that involves the delivery of very high individual doses of radiation to tumors with high precision. This allows the doctor to deliver the same amount of radiation in a much shorter time. The purpose of this study is to determine the safety of brachytherapy when combined with hypofractionated SBRT.

Primary Outcome Measures :
  1. Dose limiting toxicities (DLT) graded according to the National Cancer Institute, Common Toxicity Criteria (NCI, CTC), v 4.0 [ Time Frame: Up to 3 months ]
    Data analysis of phase I studies is descriptive. All estimates of dose-specific rates (e.g., response and toxicity) will be presented with corresponding confidence intervals using the exact method.


Secondary Outcome Measures :
  1. Late nonhematologic toxicity profile [ Time Frame: Up to 5 years ]
  2. Acute and late hematologic toxicity profile of HDR and SBRT combination [ Time Frame: Up to 5 years ]
  3. Correlation of dosimetric parameters, including dose-volume factors for bladder and rectum, with acute toxicity [ Time Frame: Up to 5 years ]
  4. Patient-reported outcomes, assessed by EPIC and AUA symptom score [ Time Frame: Up to 5 years ]

Criteria

Inclusion Criteria:

  • Adenocarcinoma of the prostate with intermediate risk disease T2b-T2c or Gleason score 7 or prostate specific antigen (PSA) 10-20 ng/ml, without metastatic disease
  • To rule out metastatic disease, patients must have the following tests:

    • Bone scan within 60 days prior to registration
    • Computed tomography (CT) of abdomen/pelvis within 60 days prior to registration
  • Karnofsky performance status > 70
  • Age > 18
  • PSA blood test within 60 days prior to registration
  • Prostate biopsy within 180 days prior to registration
  • Within 60 days prior to registration, hematologic minimal values:

    • Absolute neutrophil count > 1,500/mm^3
    • Hemoglobin > 8.0 g/dl
    • Platelet count > 100,000/mm^3
  • Men of childbearing potential must be willing to consent to using effective contraception while on treatment and for at least 3 months thereafter
  • No history of previous pelvic irradiation

Exclusion Criteria:

  • History of urological surgery or procedures predisposing to GU complications after radiation, i.e., anastomoses, stricture repair, etc. (will be determined by radiation oncologist)
  • History of prior pelvic irradiation
  • Documented distant metastatic disease
  • Prior radical prostatectomy or cryosurgery for prostate cancer
