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 naive 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 ((sic)2016). Results: A total of 327 treatment naive 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 firstline 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 e5546. The average PPPM in pre-progression was (sic)5597 compared to (sic)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.
