Classification of effects on the tumor

Uniform criteria for reporting response , recurrence, disease-free interval, and toxicity were proposed in 1979 after a meeting on the Standardization of Reporting Results of Cancer Treatment and were subsequently widely accepted.

These response criteria, known as the World Health Organization (WHO) criteria , are based largely on tumor measurements in two dimensions (the longest perpendicular diameters in the axial plane).
