Σύνοψη	The UCLA Prostate Cancer Index (UCLA PCI) is a 20-item, prostate-cancer-specific quality-of-life instrument focused on functional outcomes (urinary, sexual, bowel) rather than general cancer QoL. Developed by Litwin et al. in 1998, it has become the standard functional assessment tool in prostate cancer outcomes research, particularly for treatment comparison studies evaluating surgical vs. radiation outcomes.	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.
