Expanded Prostate Cancer Index Composite
What is EPIC?
The Expanded Prostate Cancer Index Composite (EPIC) is a comprehensive instrument designed to evaluate patient function and bother after prostate cancer treatment. Content from the original UCLA-Prostate Cancer Index (PCI) was expanded with guidance from a development cohort of localized prostate cancer patients and an expert panel comprised of urological oncologists, radiation oncologists (including brachytherapy expertise), survey researchers, and prostate cancer nurses. These experts, patients, and review of the literature suggested a need to augment the UCLA-PCI with items to capture additional concerns relevant to brachytherapy, external beam radiation, radical prostatectomy, and androgen deprivation. Accordingly, the UCLA-PCI was supplemented with specific items addressing irritative and obstructive voiding symptoms (the original UCLA-PCI had queried principally incontinence only in urinary function assessment), hematuria, additional bowel symptoms (to improve the suboptimal bowel function scale from the original UCLA-PCI) and hormonal symptoms. Symptom-specific bother items corresponding to each symptom item were added to elicit multi-item bother scales for each HRQOL domain. Responses and comments from the development cohort were incorporated to derive the final instrument: the Expanded Prostate cancer Index Composite (EPIC).

* Based on pooled averages from distribution- and anchor-based approaches.
Sample Size Table & Suggested Endpoint
If less than 100% response rate is anticipated, then sample sizes will need to be adjusted. For example, an expected 75% response rate at 2 years for a study with a single endpoint and 80% power would require 86 subjects (64/0.75 = 85.33)
