Comparing Karnofsky performance scale & ECOG performance status

To our knowledge, there is no formal mapping of the two scales in the published literature. The following table is derived from data available on the ESMO Oncology PRO website and ECOG-ACRIN. Please note that ESMO has changed assigned values over time. For example, there are differences between their 7/27/2019 version and the 10/24/2020 version.

80 1
70 1
60 2

Lansky play-performance scale for pediatric patients

This scale may be used with children age 1-16 who have any type of malignancy. It may be used for both inpatients & outpatients, and for patients undergoing active treatment as well as long-term follow-up. It is rated by parents based on their child's activity over the past week. Parents fill out the assessment based on the directions on the form, and the form is readministered over time to assess for changes in performance status.

An excerpt of the relevant directions for parents is as follows:

"Think about your child's play and activity over the past week. Think about both good days and bad days. Average out this period. Now read the descriptions and pick the one that best describes your child's play during the past week."

Rating Description
100 Fully active, normal
90 Minor restrictions with strenuous physical activity
80 Active, but gets tired more quickly
70 Both greater restriction of, and less time spent in, active play
60 Up and around, but minimal active play; keeps busy with quieter activities
50 Lying around much of the day, but gets dressed; no active play; participates in all quiet play and activities
40 Mostly in bed; participates in quiet activities
30 Stuck in bed; needs help even for quiet play
20 Often sleeping; play is entirely limited to very passive activities
10 Does not play nor get out of bed
0 unresponsive
