OBJECTIVES: The objective of this study was to describe treatment patterns, survival, healthcare use and costs in patients with metastatic renal cell carcinoma (mRCC) in a real-world setting. RESEARCH DESIGN AND METHODS: We used the National Health Insurance (NHI) claims database for the Ile-de-France region to perform a retrospective cohort analysis of patients with mRCC treated by a first-line targeted therapy. Treatment naïve patients were identified combining the 10th revision of the International Classification of Diseases (ICD-10) codes (C64 & C77-C79) and a first prescription of targeted therapies. Descriptive analyses were performed on treatment patterns and patients' characteristics. Progression free survival (PFS) and overall survival (OS) were determined using Kaplan-Meier actuarial survival analysis. All healthcare resource use and costs were estimated on a per patient per month (PPPM) basis (€2016). RESULTS: A total of 327 treatment naïve patients with mRCC were included. Median follow-up was 13.4 months. Sunitinib accounted for 73% of first-line treatments. The most frequently observed treatment sequence for the first two lines was sunitinib-everolimus (16%; n = 137) and for the first three lines sunitinib-everolimus-axitinib (20%; n = 49). First-line PFS for sunitinib, everolimus, pazopanib, sorafenib and other was 8.7, 6.2, 10.7, 5.7 and 11.2 months, respectively. Median OS for patients treated by first-line sunitinib, everolimus, pazopanib, sorafenib and other was respectively 14.7, 8.1, 21.1, 8.9 and 14.0 months. From the NHI's perspective, the mean PPPM was €5546. The average PPPM in pre-progression was €5597 compared to €5541 beyond progression of the disease. Oral targeted therapies accounted for 53% of the total PPPM. CONCLUSION: This descriptive study showed that the economic burden of mRCC is substantial with oral targeted therapies accounting for 53% of the PPPM. OS and PFS in real life are poorer than observed in clinical trials.
