Evaluation of health-related quality of life via the Computer-Based Health Evaluation System (CHES) for Japanese metastatic breast cancer patients: a single-center pilot study.

Compliance with electronic HRQOL data collection in this cohort was acceptable, considering the general ideal collection rate of 70-80%. We are conducting a prospective study to determine whether the use of CHES to input electronic real-time feedback of HRQOL ratings improves patients' overall HRQOL.
