MR-linac Guided Ultra-hypofractionated RT for Prostate Cancer (SMART-P01 and SMART-P02)
Phase II Prospective Trial of MR-linac Based Stereotactic Ablative Radiotherapy for Patients With Localized (SAMRT-P01) and Oligo-metastatic (SMART-P02) Prostate Cancer
About This Trial
- This clinical trial is studying a precise form of high-dose radiation therapy that uses real-time MRI scans to clearly see and target tumors while protecting nearby healthy tissue.
- Researchers want to learn how safe and effective this treatment is and how it affects patients' overall quality of life.
- The study is open to adults with prostate cancer that is either confined to the prostate or has only spread to a small number of other areas.
- Before considering this trial, patients should know that they must be able to safely have MRI scans and cannot have had prior pelvic radiation or recent prostate surgery.
More Information
- 1.
- To investigate the tolerability of MR-linac based stereotactic ablative radiotherapy (MRL-SBRT)for patients with localized prostate cancer 2.
- To assess the acute and late toxicities, efficacy and quality of life for patients treated by MRL-SBRT 3.
- To simulate the dose planning and assess the feasibility of simultaneous-boost for MR-prominent foci 4.
- To investigate the relationship between the changes of blood and tissue biomarkers and manifestations on mp-MRI pre-/post-MRL-SBRT, to further ascertain the predictive factors of local persisting and/or relapse disease
