Ratings of the importance of quality of life variables: therapeutic implications for patients with metastatic breast cancer.
Metastatic breast cancer cannot be cured with currently available therapeutic agents, and the objectives of treatment must, therefore, be directed towards other goals that include the relief of symptoms and the preservation or restoration of function. The main objective of the study reported here was to examine the relative importance of 28 items concerned with general health or with disease and treatment to a group of patients with metastatic breast cancer. All items concerned aspects of quality of life whose relevance and importance to patients with metastatic breast cancer had been shown in previous work. Patients rated items according to importance using two methods, a Q sort and a linear analogue rating. General health items, notably self-care, mobility, and physical activity, appetite, sleep, and family relationships were ranked in the upper quartile of the group of items rated. By contrast, items concerned directly with the common side-effects of chemotherapy were given lower rankings. The ratings were shown to be reproducible. These results emphasize the importance of including in clinical trials of therapy that are palliative in intent, endpoints that include those aspects of quality of life that are of greatest importance to patients.
