Validity of the Japanese version of functional assessment of cancer therapy-gastric (FACT-Ga) and its sensitivity to ascites volume change: a retrospective analysis of Japanese clinical trial participants

摘要

The functional assessment of cancer therapy-gastric (FACT-Ga) questionnaire was designed to evaluate quality of life (QOL) in patients with gastric cancer. We aimed to explore the reliability and validity of FACT-Ga in Japanese patients, and assess the sensitivity of the gastric cancer subscale for detecting changes in cancer-related variables over time.
