The Expanded Prostate Cancer Index Composite (EPIC) is a comprehensive instrument designed to evaluate patient function and bother after prostate cancer treatment and assesses the disease-specific aspects of prostate cancer and its therapies and comprises four summary domains (Urinary, Bowel, Sexual and Hormonal). Response options for each EPIC item form a Likert scale, and multi-item scale scores are transformed linearly to a 0-100 scale, with higher scores representing better health related quality of life. Changes in EPIC scores will be assessed during treatment and the overall median change in scores will be reported.

A PROMIS score of 50 is the average (or mean) score for a specific, relevant group of people under investigation. That group is the reference population. The PROMIS measures the responses use a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation (SD) of that population. A score of 40 is one SD lower than the mean of the reference population and a score of 60 is one SD higher than the mean of the reference population. For PROMIS measures, higher scores equals more of the concept being measured (e.g., more Fatigue). Changes in the PROMIS fatigue scores will be assessed during treatment and the overall median change in scores will be reported.

EQ-5D is a standardized instrument for measuring generic health status. The health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The respondents self-rate their level of severity for each dimension by selecting one of the following responses: no problems (0), slight problems (1), mild problems (2), moderate problems (3), or severe problems (4) with a particular dimension. Lower scores indicate less issues/problems with that particular health dimension. Changes in the EQ-5D scores will be assessed during treatment and the overall median change in scores will be reported.

The EQ-VAS records the patient's self-rated health on a vertical visual analogue scale, similar to a ruler, where the endpoints are labelled with 100='The best health you can imagine' on one end and 0='The worst health you can imagine' on the other, with 50 being the midpoint and participants mark an X on the scale to indicate how their health is on the day of the visit. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement. Changes in the EQ-VAS scores will be assessed during treatment and the overall median change in scores will be reported.
