Quality of life in geriatric oncology--An evaluation of standard questionnaires in elderly men with urological malignancies.

Quality of life (QOL) is a critical issue in elderly patients with cancer. In the geriatric population, cancer is often associated with other chronic conditions possibly affecting QOL. This prospective study aimed to evaluate the validity of two QOL questionnaires, EORTC QLQ-C30 and SF-36, in older cancer patients. Seventy-two of 87 male patients with genitourinary cancer (median age, 76 years) completed the questionnaires (83% response rate). Internal consistency reliability was high (α≥0.7), except for SF-36 cognitive function (α=0.62) and QLQ-C30 general health status (α=0.57). QLQ-C30 and SF-36 appear similarly reliable for QOL assessment in this population. However, cognitive function and functional status, two factors likely to influence the value of QOL self-assessment, are poorly taken into account whereas they are correctly explored by the comprehensive geriatric assessment (CGA) procedure. QOL assessment in elderly cancer patients should therefore be associated with CGA to better meet the expectations of clinicians.
