Prognostic value of quality of life scores in terminal cancer patients.
A multicenter cross-sectional study of 115 terminal cancer patients in eight home-care units assessed the prognostic value of quality of life scores, as measured by the Therapy Impact Questionnaire (TIQ). The analysis of the questionnaires completed by 100 patients revealed an association between survival and many of the scales: fatigue, gastrointestinal symptoms, global health status, functional impairment, emotional status, and cognitive status. This association was also observed for some specific physical symptoms, such as confusion, weakness, and loss of appetite, and the overall number of symptoms reported by the patient. Adjusting for some possible confounding factors, only confusion (among the physical symptoms), cognitive status, and global health status (among TIQ primary scales) showed independent prognostic value. As regards the latter two scales, median survival time was distributed differently for patients with no impairment of either (137 days), with impairment of one scale (50 days) and with impairment of both scales (17 days). The judgment expressed by the patient about subjective perception of general malaise and cognitive difficulties can give the clinician important prognostic information.
