Association Between Health Care Provider (HCP)-Assessed ECOG Performance Status (PS) and Overall Survival, and Objectively Measure of Physical Activity (PA) Levels in Advance-cancer Patients"

The main goal of this phase of the study is to determine if objectively assessed Physical Activity (PA) levels in advanced-cancer patients are associated with health care provider (HCP)-assessed ECOG performance status and overall survival. The purpose is to advance the evidence-base for incorporating objective assessment of Physical Activity (PA) in the context of performance status assessment in advanced cancer patients.
