NCT02334579

Brief Summary

The purpose of this study is to find out the effects (good and bad) of highly focused radiation on you and your prostate cancer. The purpose of this evaluation is to see if this treatment causes fewer side effects that other standard treatment approaches, and to evaluate the effect of this treatment on your prostate tumor and your quality of life over time.

Outcome Measures

Primary Outcomes (2)

  • Quality of life outcomes (low- and intermediate-risk prostate cancer groups)

    In the low- and intermediate-risk prostate cancer groups, to determine whether study treatment improves patient-reported quality of life outcomes compared to the approach used in a previous multi-center cyberknife stereotactic radiosurgery trial.

    8 years

  • Rates of acute and late grade 3-5 gastrointestinal and genitourinary toxicities (high-risk group)

    In the high-risk group, to estimate rates of acute and late grade 3-5 gastrointestinal and genitourinary toxicities following cyberknife stereotactic radiosurgery.

    8 years

Secondary Outcomes (3)

  • Rates of toxicities related to treatment

    5 years

  • Disease free survival

    5 years

  • Overall survival

Other Outcomes (1)

  • Quality of life

Study Arms (1)

CyberKnife Stereotactic Radiosurgery

EXPERIMENTAL

This treatment concentrates large doses of radiation onto the tumor so that injury from radiation to the nearby normal tissue will be minimal. CyberKnife Stereotactic Radiosurgery is not investigational and is considered standard of care.

Radiation: CyberKnife Stereotactic Radiosurgery

Interventions

Five treatments given over about one week.

CyberKnife Stereotactic Radiosurgery

You may qualify if:

  • Histologically proven prostate adenocarcinoma
  • Clinical stage T1a-T3, N0-Nx, M0-Mx
  • Patients belonging in one of the following risk groups: (1) LOW RISK: CS T1a-T2a, Gleason 2-6, PSA\<10, Nx-0, Mx-0; (2) INTERMEDIATE RISK: CS T2b, Gleason ≤7, PSA\<20, Nx-0, Mx-0, or CS T1a-T2b, Gleason 2-6, PSA≥10 \& \<20, Nx-0, Mx-0, or CS T1a-T2b, Gleason 7, PSA≤20, Nx-0, Mx-0; or (3) HIGH RISK: CS T2c-T3, any Gleason, any PSA, or CS T1-3, Gleason ≥8 and/or PSA≥20
  • Karnofsky performance status 70-100
  • Hormone therapy: includes LHRH agonists (e.g. leuprolide, goserelin, triptorelin), antagonists (e.g. degarelix), peripheral blockers (e.g. flutamide, bicalutamide, nilutamide), estrogens (e.g. DES) and bilateral orchiectomy
  • Low and Intermediate risk groups: no hormone ablation for two months prior to enrollment, or during treatment
  • High risk group: three hormone therapy regimens are allowed
  • alpha reductase inhibitors (e.g., finasteride or dutasteride) are allowed

You may not qualify if:

  • Prior prostatectomy or cryotherapy of the prostate
  • Prior high-dose radiotherapy to the prostate or lower pelvis
  • Implanted hardware or other material that would prohibit appropriate treatment planning or treatment delivery, in the investigator's opinion
