Quality of life and supportive care for patients with metastatic renal cell carcinoma.

ABSTRACT

In recent years, a key issue in the management of patients with metastatic renal cell carcinoma (mRCC) has been the assessment of health-related quality of life (HRQoL), particularly following the introduction of targeted therapies that have brought significant improvements in progression-free survival and quality of life in these patients. HRQoL is becoming one of the main factors influencing choice of therapy, and HRQoL experienced during first-line treatment may affect the choice of the second-line therapy. Consequently, several trials have been conducted to evaluate the impact of approved targeted therapies for mRCC on HRQoL, and this measure is being introduced with increasing frequency in the trial design. With respect to agents used after progression on cytokines, sunitinib and temsirolimus have yielded better HRQoL scores, and sorafenib and pazopanib have shown stable HRQoL scores compared with placebo. Regarding targeted agents approved for patients who progress on a first-line tyrosine kinase inhibitor, everolimus has shown to delay and reduce the degree of Karnofsky performance status deterioration compared with placebo. Moreover, evidence obtained from these trials shows that tumor response and delay in disease progression affect HRQoL. In this article, we review the different HRQoL scales used to evaluate patients with mRCC along with the results obtained in clinical trials. Given that HRQoL is determined not only by treatment-related effects but also by mRCC symptoms and its clinical complications, the characteristics and appropriate treatment of the most commonly experienced symptoms, including anorexia, fatigue, pain, anemia, and venous thromboembolism, are also reviewed.
