Precision Performance Status Compared With ECOG Performance Status

University of Southern California41 enrolled

Overview

This study compares consumer movement trackers to the Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) in monitoring cancer patient movement. The ECOG PS emphasizes a patient's ambulatory status (ability to walk around), and scores patients on a scale of 0-5: 0 (no restrictions), 1 (ambulatory), 2 (\< 50% of hours spent in bed, unable to carry out work activities), 3 (\> 50% of hours spent in bed, limited in self care), 4 (bedbound and gravely disabled) and 5 (deceased). Accurate assessment of a patient's PS is paramount in informing therapeutic decision-making, whether it be to predict response and tolerability to treatment or determine eligibility for clinical trials. However, the ECOG PS scale is observational, and therefore limited in its precision. Information gained in this study may help researchers learn if there is a better way to assess patient movement with computerized analysis tools using movement trackers.

PRIMARY OBJECTIVE: I. To determine the correlation between patient acceleration of the spine base/non-pivoting leg captured with in-office movement trackers, and physician/patient assessed Eastern Cooperative Oncology Group (ECOG) performance status (PS) using a Microsoft Kinect movement tracker. SECONDARY OBJECTIVES: I. To determine the correlation between clinician/patient assessed ECOG PS and Kinect assessed ECOG PS score. II. To determine the range of measured patient acceleration measurements for each ECOG score between 0 and 3. OUTLINE: This is an observational study. Patients undergo "Get Up and Go" assessment as well as a chair-to-table assessment during the clinic visit on study.

Outcomes

Primary Outcomes

Median acceleration at the Spine Base and non-pivoting leg

The Kinect device will record the participant performing the chair to examination table activity and the Get up and Go activity. This recording will quantify spine and non-pivoting leg mean acceleration during movement onto an examination table and the Get up and Go time. These values will be assessed for a linear or monotonic relationship with Eastern Cooperative Oncology Group (ECOG) scores. If a linear relationship is exhibited the primary objective will be evaluated via a Pearson correlation coefficient. However, the supposition is the data will more likely reflect a monotonic relationship. In this event the primary objective will be evaluated via a Kendall Rank Tau-b correlation coefficient.

Time frame: Day 1

Secondary Outcomes

Video recording assessed ECOG Performance Status (PS) measurement

The relationship between ECOG PS determined subjectively in clinic and ECOG PS determined by reviewing the Kinect recording will be assessed for a linear or monotonic relationship. However, the supposition is a linear relationship is more likely. A Pearson or Kendall Rank correlation will be utilized accordingly to evaluate a correlation.
