Retrospective assessment of everolimus treatment in patients suffering from advanced renal cell carcinoma

Objective: Results of second-line everolimus treatment in clear cell renal carcinoma. Material and methods: Clinical data of 32 patients of the Clinic of Systemic and Metastatic Malignancies, Centre of Oncology, Maria Sklodowska-Curie Memorial Institute (Krakow Branch) treated with second-line everolimus between 2011 and 2016 were analysed. Results: Median progression-free survival was 7 months. Stable disease was observed in 24 cases. Adverse events occurred in 59% of all patients, and the majority were mild and moderate (G1 and G2) according to CTCAE. The most frequent adverse events included anaemia, stomatitis, rash and fatigue. Conclusion: Molecularly targeted drugs offer the only effective and available therapy in Poland, which can be administered in patients with advanced renal cell carcinoma. Second-line everolimus is a valuable therapeutic option in the above mentioned group (following progression on first-line TKI therapy), especially when it is necessary to avoid the accumulation of similar adverse events after TKI treatment (different toxicity profiles).
