Cancer Outcomes Measurement Working Group (COMET)

The Cancer Outcomes Measurement Working Group (COMET) is an organization that develops standardized tools and methods to measure and compare how cancer treatments and care impact patients’ health and quality of life. By creating consistent ways to assess outcomes, COMET helps researchers, clinicians, and patients understand the effectiveness of different therapies, promote best practices, and improve cancer care worldwide. This ensures that measurements are reliable, meaningful, and can be used across studies, ultimately supporting better decision-making and improved patient outcomes in cancer treatment.
