Repeated Assessments of Symptom Severity Improve Predictions for Risk of Death Among Patients With Cancer

CONTEXT: Although prior studies show the importance of self-reported symptom scores as predictors of cancer survival, most are based on scores recorded at a single point in time. OBJECTIVES: To show that information on repeated assessments of symptom severity improves predictions for risk of death and to use updated symptom information for determining whether worsening of symptom scores is associated with a higher hazard of death.
