Podsumowanie	The FACT-Ovarian (FACT-O) is a disease-specific quality-of-life measure for women with ovarian cancer, integrating the 27-item FACT-G core with a 12-item ovarian-specific subscale addressing cancer-related symptoms, sexual function, abdominal distension, and treatment side effects. Validated by Basen-Engquist et al. in 2001, it is a standard endpoint in ovarian cancer clinical trials and supportive care research.	The EORTC QLQ-BR23 is a 23-item breast-cancer-specific module designed to complement the 30-item EORTC QLQ-C30 core questionnaire, assessing functional and symptom domains unique to breast cancer. Validated by Sprangers et al. in 1996, it measures body image, sexual function, breast symptoms, and arm symptoms, making it a standard instrument in European and international breast cancer clinical trials and quality-of-life research.
