Cancer prognosis and performance assessment tools. The ECOG Performance Status scale is the most widely used measure of functional capacity in oncology, influencing chemotherapy eligibility, clinical trial enrolment, and goals-of-care discussions. It grades patients from 0 (fully active) to 5 (dead) based on ambulatory status and ability to perform activities of daily living. While this is a single-calculator category, the ECOG score is one of the most frequently applied instruments in oncology practice and research. It should be interpreted alongside tumour staging, molecular markers, comorbidity burden, and patient preferences regarding treatment intensity.
Every tool in this domain is linked below, each with its own formula, inputs, and interpretation notes. Starting from the clinical area instead of the subject? The same calculators are grouped on the specialties pages, the full alphabetical list collects everything in one place, and the comparison tool lines up three tools side by side.
