  found on ACCC’s web site at www.accc-cancer.org/publications/pgsga.pdf, and www.accc-cancer.org/publications/pgsgaworksheet.pdf.
  The PG-SGA addresses the global status of the patient from this integrated perspective—weight loss and weight loss history, nutritional
  intake, nutrition impact symptoms, ECOG performance status in patient terms, metabolic/catabolic stresses, and physical examination
  focused on body composition. From the standpoint of functionality, ECOG or Karnofsky performance status assessments are impor-
  tant prognostic indicators, but greater insight may be obtained in terms of functionality and QOS with questions addressing change in
  functioning as it impacts that survivor.
