Definition : The presence of more residual tumor than for partial response but less than for progressive
disease. Using WHO criteria, stable disease is defined as less than 50 percent reduction
in tumor load of all measurable masses determined by two studies at least four weeks
apart. With the RECIST criteria, stable disease is defined as less than a 30 percent
decrease in the sum of the longest diameter of up to 5 index tumors using the sum
of the baseline longest diameters as a denominator.;
