Health Related Quality of Life in Japanese Men With Localized Prostate Cancer Treated With Current Multiple Modalities Assessed by a Newly Developed Japanese Version of the Expanded Prostate Cancer Index Composite

Abstract

Reliability and validity of the Japanese version of the Extended Prostate Cancer Index Composite were verified, although revision is needed for it to be more comprehensible for elderly patients and those with low education. It can be used for cross-cultural assessment of health related quality of life in patients with localized prostate cancer treated with current multidisciplinary treatment modalities.
