Sintesi	The FACT-G is a 27-item self-report questionnaire measuring health-related quality of life in cancer patients across four key domains: physical, social/family, emotional, and functional well-being. Developed by Cella et al. in 1993, it has become one of the most widely used generic QoL instruments in oncology research and clinical practice, translated into 40+ languages and validated across diverse cancer populations.	The FACT-B is a comprehensive 36-item disease-specific quality-of-life instrument that integrates the generic FACT-G (27 items covering physical, social, emotional, and functional well-being) with a 9-item breast-cancer-specific subscale addressing body image, sexual function, arm symptoms, and treatment side effects. Developed by Brady et al. in 1997, the FACT-B is the gold-standard QoL measure for breast cancer research and clinical practice, used in hundreds of clinical trials and enabling comparison across breast cancer populations and treatment modalities.
