Treatment effects are typically measured through clinical trials. The most common types of clinical trials are randomized controlled trials (RCTs), which provide high-quality evidence by minimizing bias. Key metrics used to measure treatment effects include:
Overall Survival (OS): The length of time from the start of treatment until death from any cause. Progression-Free Survival (PFS): The length of time during and after treatment that a patient lives with the disease without it getting worse. Response Rate (RR): The proportion of patients whose cancer shrinks or disappears after treatment. Quality of Life (QoL): A measure of a patient’s overall well-being, including physical, emotional, and social aspects.
