Development of a patient-reported questionnaire for collecting toxicity data following prostate brachytherapy.

Purpose: To improve a questionnaire used to collect patient-reported outcomes from patients with early stage prostate cancer treated with brachytherapy. A secondary aim was to adapt the Late Effects of Normal Tissue (LENT) subjective toxicity questionnaire for use to collect Common Terminology Criteria for Adverse Events (CTCAE) data, the current preferred platform for assessing radiation toxicity.

Materials And Methods: Three hundred and seventy-seven patients were treated with permanent iodine-125 seed implant brachytherapy for early prostate cancer.
