Development of a disease-specific health-related quality of life (HRQoL) questionnaire intended to be used in conjunction with the general European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) in renal cell carcinoma patients

Background. Studying health-related quality of life (HRQoL) following cancer treatment has become part of a growing number of standardized treatment protocols. The European Organization for Research and Treatment of Cancer (EORTC) has developed HRQoL questionnaires aimed at cancer patients. A disease-specific part is not available for renal cell carcinoma (RCC) patients, and the present aim was to develop an EORTC-compatible RCC-specific HRQoL questionnaire.Material and methods. In total 413 RCC patients were treated with radical or partial nephrectomies in Western Norway during the period from 1997 to 2010. Three hundred and nine patients with histologically proven cancer were still alive at the inclusion time point and 185 RCC patients (71% response rate) returned the questionnaires. We determined HRQoL by the EORTC-QLQ C30 questionnaire. We also asked 13 candidates questions aimed at constituting a disease-specific part. Furthermore, we tested parts of personality by the Eysenck Personality Inventory a...
