Treatment patterns, outcomes and clinical characteristics in advanced renal cell carcinoma: a real-world US study.

Aim: Assessing treatment patterns, outcomes and clinical characteristics in advanced renal cell carcinoma clinical practice. Materials & methods: A US cross-sectional physician survey conducted February-September 2019. Results: Surveyed physicians reported first-line treatment of 445 patients involving tyrosine kinase inhibitor monotherapy (51.0%), immuno-oncology (IO/IO combination) therapy (25.8%) or other regimens (23.1%). A total of 60.9% had physician-assessed IMDC risk. Of these 61.9, 50.9 and 27.6% of patients with favorable, intermediate and poor risk, respectively, received tyrosine kinase inhibitor monotherapy. A total of 16.7, 26.9 and 34.5% of patients with favorable, intermediate or poor risk received IO/IO combination therapy. Complete/partial responses (∼35% patients) remained comparable across first-line treatments. Conclusion: Guideline-recommended therapies are not widely prescribed. Many patients experienced poor clinical outcomes highlighting a need for more effective treatments.
