* Methods: Patients with low-risk and favorable intermediate-risk prostate cancer received a hydrogel spacer and fiducial markers before receiving targeted radiation therapy, with various questionnaires used to assess quality of life before and after treatment.
* Results: In a small group of 20 patients, treatment showed minor positive and negative impacts on urinary, bowel, sexual, and hormonal functions, with low rates of side effects, while PSA levels decreased on average, indicating a potential treatment benefit.
