研究目的:

本研究以两个化疗周期内2 级及以上化疗相关血小板减少症(血小板 < 75×10?/L) 发生率为主要终点,同时围绕血小板计数变化、重度血小板减少发生率、出血事件、化疗调整情况等设置多项次要终点,旨在明确 rhTPO 联合 TPO-RA 方案的疗效与安全性。  

Objectives of Study:

The primary endpoint of this study was the incidence of grade 2 or higher chemotherapy-induced thrombocytopenia (platelet count < 75×10?/L) within two chemotherapy cycles. Multiple secondary endpoints were also set, including changes in platelet count, incidence of severe thrombocytopenia, bleeding events, and chemotherapy adjustments, to clarify the efficacy and safety of the rhTPO combined with TPO-RA regimen.
