Toxicity is often measured using standardized grading systems, such as the Common Terminology Criteria for Adverse Events (CTCAE), which categorizes the severity of side effects on a scale from 1 (mild) to 5 (death related to adverse event). Other methods include:
Patient-reported outcome measures (PROMs): Surveys and questionnaires that capture the patient's perspective on their symptoms and quality of life. Biomarkers: Biological indicators, such as blood tests, that can signal organ damage or dysfunction. Imaging studies: Techniques like MRI and CT scans to detect structural changes in organs.
