Instruments for quality of life assessment in patients with gastrointestinal cancer.
Health-related quality of life (HRQoL) is a multi-dimensional concept, encompassing all aspects of patient health and used widely as an outcome measure in clinical trials. In this review, the current status of HRQoL assessment in clinical studies of gastrointestinal cancer is examined and the various instruments proposed for this purpose are considered and compared. The cancer-specific questionnaires, among them the Spitzer Quality of Life Index, the Rotterdam Symptom Check List, the Functional Living Index-Cancer, the Functional Assessment of Cancer Therapy General (FACT-G) and the Quality of Life Questionnaire of the European Organization for Research and Treatment in Cancer (EORTC), provide essential information about particular concerns of cancer patients and are most sensitive in detecting changes over time. The domain-specific questionnaires, among them the Multidimensional Fatigue Inventory, the McGill Pain Questionnaire, the Hospital Anxiety and Depression Scale and the Anorectal Sphincter-Conservative Treatment Questionnaire, are designed to assess one specific domain of quality of life. The core-module cancer-specific questionnaires combine a core questionnaire for use in any type of cancer with a module questionnaire which assesses specific issues in cancer patient subgroups. Such core-module instruments have been evaluated for colorectal, pancreatic, hepatobiliary, oesophageal and gastric cancer. The most valid and standardized instruments for HRQoL assessment in cancer patients are the EORTC and the FACT questionnaires, which are widely used in Europe and around the world. Data provided by these specific instruments complement clinical outcomes and may help to evaluate the costs and benefits of different treatment options, thus being essential to further improvement of treatment and care of cancer patients.
