The Functional Assessment of Cancer Therapy – General (FACT-G) is a 27-item questionnaire designed to measure four domains of HRQOL in cancer patients: Physical, social, emotional, and functional well-being. Original development and validation involved 854 patients with cancer and 15 oncology specialists.

The FACT-G meets or exceeds all requirements for use in oncology clinical trials, including ease of administration, brevity, reliability, validity, and responsiveness to clinical change. Selecting it for a clinical trial adds the capability to assess the relative weight of various aspects of QL from.
The use of the combined FACT- G and FACT-Br Subscale to assess QoL specifically in patients with brain metastases has successfully undergone psychometric validation . Future clinical trials should use the FACT- G and FACT-Br Subscale to assess QoL in this patient population.
