The FACT-G questionnaire is used with patients of any tumor type to assess patient quality of life (QoL). FACT-G is a self-administered, 28-item questionnaire assessing physical, functional, social and emotional well-being, as well as patient satisfaction with treatment. All questions in the FACT-G use a 5-point rating scale (0 = Not at all; 1 = A little bit; 2 = Somewhat; 3 = Quite a bit; and 4 = Very much). The FACT-G total score is computed as the sum of the four subscale scores and has a possible range of 0-108. Higher scores indicate better QoL. Change in FACT-G was analyzed using repeated measures mixed effects general linear model (GLM). A positive change from baseline indicates improved QoL.
