Conversion of Karnofsky Performance Status (Kps) and Eastern Cooperative Oncology Group Performance Status (Ecog) to Palliative Performance Scale (Pps), and the interchangeability of Pps and Kps in Prognostic Tools

Abstract

The PPS and the KPS can be used interchangeably as functional tools and within prognostic tools. The ECOG is interchangeable with the PPS and the KPS, but this interchangeability is population-specific.
