Quality of life in prostate cancer patients receiving particle radiotherapy: A review of the literature

Proton and carbon ion radiotherapy for the treatment of prostate cancer is associated with a lower incidence of adverse events than conventional radiotherapy. There are few reports on the quality of life of patients treated with particle therapy, and limited patient‐reported outcomes. Analysis of quality of life is important for patients treated with radiotherapy alone or in combination with hormonal therapy, and long‐term results, dose fractionation and costs need to be included in the analysis. This information might help both clinical decision‐making and selection of appropriate treatments according to the individual needs of patients. This study reviews the literature on the quality of life and outcomes of patients treated with particle therapy, and discusses future directions.
