What is EORTC QLQ-C30
The EORTC QLQ-C30 is a trusted tool for checking the quality of life in cancer patients. It helps doctors understand a patient's health journey better. This thirty-item questionnaire covers a broad range of cancer-specific issues. It mixes multi-item scales with single items to capture the full picture of a patient's status. It looks at five functional areas like physical and emotional health plus symptom scales for fatigue and pain. Most questions use a simple one-to-four scale, while the overall health rating uses a one-to-seven range so patients can easily share exactly how they feel. Clinicians use this tool in trials and daily practice to track changes over time. It is reliable and valid across many cultures. By spotting issues early, healthcare teams can adjust treatments to support patient wellbeing and ensure that care plans truly meet the specific needs of the individual.
The EORTC QLQ-C30 is scored using a standardised method that converts raw answers into a 0 to 100 scale. You start by averaging the items within each scale to find the Raw Score. Then, use a linear transformation formula to shift these numbers to a 0 to 100 range. It is crucial to watch the direction here. For functional scales and global health status, a higher score means better function. However, for symptom scales like pain or fatigue, a higher score points to more severe problems. This clear distinction helps doctors spot changes in a patients quality of life during cancer care.
