OBJECTIVE: To characterize the impact of sorafenib treatment on health-related quality of life (HRQL) in Japanese patients with mRCC. PATIENTS AND METHODS: We performed a prospective observational study including 85 consecutive patients undergoing radical nephrectomy who were diagnosed as having mRCC refractory to cytokine therapy and subsequently treated with sorafenib for at least 3 months. HRQL in these patients was assessed using the Medical Outcomes Study 36-Item Short Form (SF-36). RESULTS: Before treatment all eight scores in the 85 patients were significantly inferior to those in the age-matched control population in Japan. Three months after sorafenib treatment, one score (mental health) in the 85 patients was significantly higher than what it was before treatment. Three scores (body pain, role limitations because of emotional problems, mental health) in patients who had some degree of tumour shrinkage were significantly better than those in the remaining patients, while there were no significant differences in all but one score (social function) between patients with and without severe AEs. Furthermore, there were no significant differences in any scores 3, 6 and 12 months after sorafenib treatment in 26 patients who could be followed for at least 12 months. CONCLUSIONS: Despite non-randomized study including a comparatively small number of patients, the findings of the present study suggest that sorafenib treatment may not impair HRQL in patients with mRCC, and HRQL in patients receiving sorafenib is likely to be affected by the efficacy rather than AEs during treatment.
