RECIST 1.1 PR/CR/SD/PD Response Thresholds

Apply RECIST 1.1 criteria to measure solid tumor response: CR (disappearance), PR (30% decrease), PD (20% increase plus 5 mm absolute), SD (neither PR nor PD) from sum of target lesion diameters.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Apply RECIST 1.1 criteria to measure solid tumor response: CR (disappearance), PR (30% decrease), PD (20% increase plus 5 mm absolute), SD (neither PR nor PD) from sum of target lesion diameters

Each component has a specific meaning:

  • Sum of target lesion diameters — The sum of target lesion diameters recorded for the scenario being assessed.

Note: Interpret the recist 1.1 result against the thresholds and context described above.

How to Use

Enter the sum of target lesion diameters for the scenario you are assessing. Apply RECIST 1.1 criteria to measure solid tumor response: CR (disappearance), PR (30% decrease), PD (20% increase plus 5 mm absolute), SD (neither PR nor PD) from sum of target lesion diameters. Use the recist 1.1 result to inform your calculation.
