[Multicentric Hungarian results of cabozantinib therapy in patients with metastatic kidney cancer based on real-world data]. / Áttétes vesedaganatos betegek kabozantinibterápiájának multicentrikus magyarországi eredményei.

The aim of our analysis was to evaluate the efficacy of cabozantinib in patients with metastatic renal cell carcinoma. Cabozantinib therapy initiated between 01/01/2019 and 31/12/2022 was evaluated based on a retrospective review of data from 14 renal centers in Hungary. The starting dose was 60 or 40 mg. Physical examinations and laboratory tests were performed every 4 weeks and imaging studies 3-monthly. Tumor response was assessed according to RECIST 1.1, and toxicity according to NCI CTCAE 4.0. A total of 230 patient records were evaluated, 201 (87.4%) of them had clear cell RCC. Cabozantinib was administered as third, second and first-line treatment in 48.7%, 38.3% and <5% of cases, respectively. Dose reductions occurred in 62.6% and treatment interruption in 6.5%. Duration of therapy was 10.03 months, which was independent of dose reduction. Overall tumor response rate was 39.2% and clinical benefit was 82.8%. The duration of first-, second-, third- and fourth-line treatment was 11.47, 8.03, 11.57 and 10.13 months, respectively. Overall survival from the start of therapy was 22.0 months. Cabozantinib therapy in daily practice was more beneficial than according to registry study results. Dose reduction did not affect efficacy.
