Studies have shown a risk of late toxicity from the radiotherapy, such as second cancer, heart failure and lung toxicity. With proton therapy the dose to normal tissue can be minimised without compromising the dose to the tumor. The aim of our study is to investigate whether proton therapy can be delivered in a safe way to Hodgkin Lymphoma patients with less late side effects than conventional radiotherapy, while retaining the high cure rate.\n\nThis is a multicentre phase II study of PBS proton beam therapy in patients ≤60 years, with early stage Hodgkin Lymphoma treated with induction chemotherapy. The study is performed in a non-inferiority setting comparing with a historical population-based consecutive Swedish material.
