Lurbinectedin is an alkylating agent approved for the second-line treatment of small cell lung cancer. Although initial studies showed no association between body surface area (BSA) and drug clearance, the recommended dose is 3.2 mg/m every 3 weeks. This recommendation was based on an exposure-response study, which demonstrated that patients with lower BSA had a higher incidence of thrombocytopenia. Herein we present the factors associated with BSA and thrombopoiesis, which may have contributed to the observed relationship.
鲁比卡丁是一种烷化剂,被批准用于小细胞肺癌的二线治疗。尽管最初的研究表明,体表面积(BSA)与药物清除率之间没有关联,但推荐剂量为每 3 周 3.2 毫克/平方米。这一推荐是基于一项暴露-反应研究得出的,该研究表明 BSA 较低的患者血小板减少症的发生率更高。在此,我们介绍了与 BSA 和血小板生成相关的因素,这些因素可能导致了观察到的关系。
