Evaluating CyberKnife for treating prostate cancer

Prospective Evaluation of Hypofractionated Stereotactic RT (SBRT) Using CyberKnife for Patients With Low and Intermediate Risk of Progression Prostate Cancer.

Not applicable Interventional The Greater Poland Cancer Centre · NCT03225235

This study is testing if a special type of radiation treatment called CyberKnife can help men with low to intermediate risk prostate cancer and looks at certain proteins to see how they might affect the results.

What this trial studies

This study evaluates the effectiveness of hypofractionated stereotactic radiotherapy (SBRT) using CyberKnife technology for men with low to intermediate risk prostate cancer. It focuses on assessing the prognostic and predictive value of specific proteins (PTEN, SMAD4, Cyclin D1, SPP1) in relation to treatment outcomes. Participants will undergo SBRT and their responses will be monitored to determine the therapy's efficacy. The study aims to provide insights into personalized treatment approaches for prostate cancer patients.

Who should consider this trial

Good fit: Ideal candidates are men aged 40 to 75 with confirmed adenocarcinoma prostate and low to intermediate risk of progression.

Not a fit: Patients with active cancer other than skin cancer or those who have undergone prior surgical or radiotherapy treatments in the pelvic area may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and tailored treatment options for patients with prostate cancer.

How similar studies have performed: Other studies have shown promise with similar SBRT approaches, indicating potential for success in this novel application.
