Cross‐sectional study of therapy‐related expectations/concerns of patients with metastatic renal cell carcinoma and physicians in Japan

Abstract

Abstract Objective To achieve patient‐centricity in metastatic renal cell carcinoma (mRCC) treatment, it is essential to clarify the differences in perspectives between patients and physicians. This cross‐sectional analysis of a web survey aimed to clarify the differences in expectations and concerns between mRCC patients and physicians regarding systemic mRCC therapy in Japan. Methods Surveys from 83 patients and 165 physicians were analyzed. Results The top three most significant differences in expectations of systemic therapy between patients and physicians (patient‐based physician value) were “Chance of achieving treatment‐free status” (−30.1%, p < 0.001), “Longer survival” (+25.8%, p < 0.001), and “Chance of eliminating all evidence of disease” (−25.6%, p < 0.001). The top three most significant differences in concerns for systemic therapy between patients and physicians (patient‐based physician value) were “Lack of efficacy” (+36.1%, p < 0.001), “Lack of knowledge of treatment” (−28.2%, p < 0.001), and “Daily activities affected by side effects” (+22.3%, p < 0.001). Diarrhea, fatigue/malaise, and nausea/vomiting were patients' most distressing adverse events; 50.6% of patients had difficulty telling their physicians about adverse events such as fatigue, anxiety, and depression. Conclusions This study demonstrated a gap between patients with mRCC and physicians in their expectations and concerns for systemic therapy. Japanese patients with mRCC suffer from a number of adverse events, some of which are not shared with physicians. This study highlights the importance of communicating well with patients in clinical practice to achieve patient‐centricity in systemic treatment for mRCC.
