Treatment characteristics for nonmetastatic castration-resistant prostate cancer in the United States, Europe and Japan

Abstract

Aim: We conducted this study to describe nonmetastatic castration-resistant prostate cancer (nmCRPC) patient characteristics and treatment patterns in the US, Europe and Japan. Materials & methods: Descriptive analyses were conducted using the 2015-2017 Ipsos Global Oncology Monitor Database. Results: A total of 2065 (442 in the US, 509 in Europe and 1114 in Japan) patients (median age: 74-80 years; stage III at diagnosis: 38.5%; Eastern Cooperative Oncology Group [ECOG] score ≤1: 79.4%; treated by urologist: 88.4%) were included in the analytic cohort. Luteinizing hormone-releasing hormone agonists and antiandrogens were the most commonly used first regimen treatments. With subsequent nmCRPC regimens their use decreased, while the use of chemotherapy, corticosteroids, androgen synthesis inhibitors and second-generation androgen receptor inhibitors increased. Conclusion: These data represent real-world treatment patterns in nmCRPC.
