PRISTINE Trial: PRoton Beam Therapy In Seminoma - Toxicity INvestigation and Evaluation of Outcome (PRISTINE)
Stage II seminoma is a type of cancer that is usually highly curable and most often affects young men.
Radiotherapy is an effective treatment, but it can sometimes cause side effects in the long term and, rarely, increase the risk of developing another cancer later in life.For this reason, more targeted treatments are being explored, such as proton therapy (PBT). This type of radiotherapy uses protons to better focus the treatment on the tumor while reducing exposure to the surrounding healthy tissues.The goal is to treat the cancer effectively while minimizing side effects as much as possible.
