No matter which group you are assigned to, you will be given questionnaires to study health-related quality of life. These questionnaires will take about 15 minutes to complete and will be given to you before therapy begins. Within 1-2 weeks before starting radiation therapy, you will answer a health-related quality of life questionnaire (Expanded Prostate Cancer Index Composite-SF12-AUASI). Participants who are receiving hormonal therapy will also be given this questionnaire within one week before hormonal therapy. During radiotherapy, you will be examined every week, and severe side effects and reactions will be recorded using the modified acute toxicity scale. During radiotherapy, you also will be given the EPIC-26 Short Form at Weeks 4 and 8.
