NCT00667888

Brief Summary

The goal of this clinical research study is to compare using external beam radiotherapy with intensity modulated beams for fewer days at a higher dose per day to the same type of therapy for more days at a lower dose per day in the treatment of prostate cancer. The safety of these treatments will also be studied and compared.

Outcome Measures

Primary Outcomes (1)

  • Conventional Radiotherapy (CIMRT) Versus Hypofractionated Radiotherapy (HIMRT)

    To determine the progression of the number of participants who failed treatment after receiving (CIMRT) versus (HIMRT). PSA measured on (CIMRT) and (HIMRT) for each participant on both arms. Failure was defined as Prostate-specific antigen (PSA) failure using the Phoenix definition of nadir plus 2 ng/ml, or initiation of salvage therapy.

Study Arms (2)

Intensity Modulated Radiotherapy (IMRT)

ACTIVE COMPARATOR

A total dose of 75.6 Gy will be delivered in 42 fractions to the planning target volume (PTV).

Radiation: Conventional Fractionated Intensity Modulated Radiotherapy

Hypofractionated Intensity Modulated Radiotherapy (HIMRT)

EXPERIMENTAL

A total dose of 72 Gy will be delivered in 30 fractions to the PTV.

Radiation: Hypofractionated Intensity Modulated Radiotherapy

Interventions

A total dose of 75.6 Gy will be delivered in 42 fractions to the planning target volume (PTV).

Also known as: IMRT

Eligibility Criteria

Sexmale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Biopsy proof of adenocarcinoma of the prostate.
  • Bone scan (If PSA \>10 ng/ml or T3 disease) within 3 months of starting androgen ablation or signing protocol consent if no androgen ablation.
  • CT-scan of pelvis (If Stage T3 disease) within 3 months of starting androgen ablation or signing protocol consent if no androgen ablation.
  • Suitable medical condition; Zubrod \<2.
  • Pretreatment PSA \</=20 ng/ml. If PSA \<4, must have Gleason greater than or equal to 7 and/or Stage T2b-T2c. PSA within 30 days of signing protocol consent. If neoadjuvant androgen ablation has been given, then the preandrogen ablation PSA should be used for stratification.
  • Clinical (palpable) Stage T1b - T3b disease (1992 AJCC staging system).
  • While a transrectal ultrasound will be obtained before treatment, the staging will not be based on these findings. If palpable T3 disease is present, then must have Gleason score \<8 and pretreatment PSA less than or equal to 10 ng/ml
  • Gleason score \<10.
  • If Gleason score 8 or 9, then must have stage T1/T2 disease and pretreatment PSA less than or equal to 10 ng/ml.
  • The patient must be able to understand the protocol and adhere to follow-up at 6-month intervals for the first 2 years and at yearly intervals thereafter.
  • Informed consent must be given.
  • Patients randomized to Arm 1 may also participate in protocol 2004-0428.

You may not qualify if:

  • Prior pelvic radiotherapy.
  • Greater than 4 months of prior hormone ablation therapy.
  • Prior or planned radical prostate surgery.
  • Clinical, radiographic or pathologic evidence of nodal or distant metastatic disease.
  • Concurrent, active malignancy, other than nonmetastatic skin cancer or early stage -chronic lymphocytic leukemia (well-differentiated small cell lymphocytic lymphoma). If a prior malignancy is in remission for greater than or equal to 5 yr then the patient is eligible.
  • Zubrod status greater than or equal to 2.
  • Pretreatment PSA \>20 ng/ml.
  • Gleason score of 10.
  • Palpable stage T3c (seminal vesicle involvement) or T4 disease.
