The EORTC-CLL17 is a specific questionnaire that supplements the EORTC QLQ-C30 for participants with CLL.
EORTC-CLL17 comprises 17 items divided into three subscales: symptom burden, physical condition/fatigue, and worries/fears about the health and functioning.

A high score represents a high level of symptomology high level of physical condition/fatigue, and a high level of worries/fears about the health and functioning.
