What this trial studies

This study evaluates the effectiveness and side effects of CyberKnife stereotactic ablative body radiation (SABR) in patients with prostate cancer. The CyberKnife system uses advanced technology to deliver high doses of radiation precisely to the tumor while minimizing damage to surrounding healthy tissue. The study aims to determine if this treatment can improve patient outcomes and assess its impact on quality of life over time. Patients with low to intermediate risk prostate cancer will be monitored for their response to this innovative treatment approach.

Who should consider this trial

Good fit: Ideal candidates for this study are men with histologically proven prostate adenocarcinoma who have not undergone prior prostatectomy or radiotherapy.

Not a fit: Patients with advanced prostate cancer or those who have had previous treatments such as prostatectomy or cryotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a more effective and less invasive option for patients with prostate cancer, potentially leading to quicker recovery times and improved quality of life.

How similar studies have performed: Other studies have shown promising results with similar stereotactic radiation approaches, indicating potential for success with this novel treatment.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion

* Histologically proven prostate adenocarcinoma
* Biopsy within 12 months of date of registration required except for patients who already meet criteria for enrollment in the high risk arm of the protocol. For these patients, repeat biopsy will be at the discretion of the treating physician. In general, repeat biopsy is recommended for these patients, but is not required if it will not affect the treating physician's management decisions in regards to the care of the patient.
* Clinical Stage I-IV, MX-M0 (AJCC VERSION 9)
* M-stage determined by physical exam, CT, MRI, bone scan, PSMA PET/CT, or biopsy.
* Prostate volume: ≤ 100 cc (recommended not required)
* Determined using: volume = π/6 x length x height x width
* Measurement from CT, MRI or ultrasound ≤ 90 days prior to registration.
* Eastern Cooperative Oncology Group (ECOG) performance status 0-1
* No prior prostatectomy or cryotherapy of the prostate
* No prior radiotherapy to the prostate or lower pelvis
* No implanted hardware or other material that would prohibit appropriate treatment planning or treatment delivery, in the investigator's opinion.
* Completion of patient questionnaires in section 3.7.
* Consent signed

Exclusion

* No prior prostatectomy or cryotherapy of the prostate
* No prior radiotherapy to the prostate or lower pelvis
* No implanted hardware or other material that would prohibit appropriate treatment planning or treatment delivery, in the investigator's opinion.
