Intensity Modulated Versus Interstitial - Radiation Therapy

This study has suspended participant recruitment.
(Accrual has been very slow. We are currently determining whether or not to keep the trial going as is or to close the trial and write a new protocol.)

The purpose of this trial is to compare two different treatment options for patients with low risk and low-tier intermediate risk prostate cancer. The two treatment arms being compared in this study are: (control arm) permanent interstitial prostate brachytherapy (PIPB) VERSUS (experimental arm) intensity modulated external beam radiation therapy (IMRT).


The acute and late toxicities experienced by patients in the experimental arm (IMRT) are not significantly worse then the toxicities experienced by patients in the control arm (PIPB).

Primary Outcome Measures:
  • The primary end point of this study is the acute and late toxicities of the therapeutic interventions.

Secondary Outcome Measures:
  • The willingness of eligible patients to be randomized to the treatment interventions.
  • Obstacles to accrual that need to be addressed.
  • Testing our ability to meet accrual targets.
  • Checking quality assurance benchmarks for IMRT and PIPB procedures.
  • Discovering and relieving bottlenecks in IMRT planning and procedures.
  • Quality of life.
  • Pathological local control.
  • Biochemical relapse-free survival.
  • Metastasis-free survival.
  • Overall survival.

  13. Patients must not have any hormonal therapy planned as part of the therapeutic intervention.
  14. Patients must have prostate volumes < 60 cm3 on transrectal ultrasound.
  15. Patients must not have received prior surgical treatment for prostate cancer including TURP, TURB, cryotherapy, laser ablation or microwave therapy.

  17. Patients must have an International Prostate Symptom Score (IPSS) of less than 20.
  18. Patients must have no history of previous malignancies, except non-melanoma skin tumors.
  19. Patients must have a body mass index (BMI) of <= 32.

Exclusion Criteria:

Those patients who do not meet the inclusion criteria described above will be excluded from participation.
