Doctors treated 60 patients with intermediate-risk prostate cancer using a new radiation method. They used online MRI guidance to adjust the dose during the session. The goal was to hit the tumor hard while sparing healthy tissue. This technique worked for most people in the study.
The main goal was technical feasibility. Doctors defined success as delivering a specific dose to the tumor in at least 90% of patients. They reached this goal in 46 of the 54 patients included in the analysis. That is 85% of the group.
Results varied slightly by hospital. Two of the three institutes reached the goal in 90% of their patients. The third institute reached it in 71% of their patients. The study did not report any safety issues or side effects.
However, the study has a limitation. Doctors could not guarantee full coverage of the tumor area because they did not use a gating strategy. This means the results might not apply to every situation. More research is needed to confirm these findings.
