Sažetak	The EORTC QLQ-LC13 is a 13-item lung-cancer-specific module designed to complement the 30-item EORTC QLQ-C30 core questionnaire. Developed and validated by Bergman et al. in 1994, it measures lung-specific symptoms (dyspnea, cough, hemoptysis, chest pain) and treatment toxicities (sore mouth, dysphagia). It is the standard lung cancer-specific QoL instrument in European and international trials.	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.
