叶定伟教授:维持去势状态仍然是CRPC患者的基础治疗方法

2018-07-11 佚名 ioncology

激素敏感性晚期前列腺癌患者经历2~3年的内分泌治疗后,大多数患者都将进展至CRPC阶段。在CRPC阶段,维持患者的去势状态是必要的;促黄体生成素释放激素类似物(LHRHa)是CRPC患者内分泌治疗的基石。

激素敏感性晚期前列腺癌患者经历2~3年的内分泌治疗后,大多数患者都将进展至CRPC阶段。在CRPC阶段,维持患者的去势状态是必要的;促黄体生成素释放激素类似物(LHRHa)是CRPC患者内分泌治疗的基石。

去势抵抗性前列腺癌是否需维持睾酮去势水平?

诊断为CRPC后仍需要监测睾酮水平,通过手术或药物维持去势状态仍然是CRPC患者的基础治疗方法(手术去势的临床应用已经越来越少)。事实上,目前所有关于CRPC治疗的临床试验均是在维持患者去势状态的基础上开展的。

近几年,有效的新型内分泌治疗药物不断出现,在CRPC和激素敏感型前列腺癌患者中都显示出优越疗效,比如阿比特龙等新型抗雄药物。然而,我们需要强调一点,这些新型抗雄药物替代不了LHRHa的去势功能。无论是去势抵抗还是激素敏感型前列腺癌的内分泌治疗,都需要把去势治疗作为基础。

CRPC患者的治疗,需要在维持睾酮的去势水平基础上,根据有无转移及临床症状调整治疗方案,给予LHRHa类药物联合新型内分泌治疗或化疗。LHRHa依然是CRPC患者内分泌治疗的基石。

在临床常用的去势药物中,哪种LHRHa在维持睾酮去势水平方面更有优势?

在国内,LHRH拮抗剂还没上市,LHRH激动剂是临床常用的去势治疗药物。临床上要高度重视LHRHa在降低血清睾酮使患者达到去势水平的效果。很多国内同道认为不同的LHRHa除了在药品存储、针头、注射方式和使用方便性上小有不同,在睾酮水平控制方面基本相当,然而事实上并非如此。

在琳琳总总的LHRH激动剂中,我在临床实践中发现亮丙瑞林在降低血清睾酮方面表现非常出色,在内分泌治疗期间可将睾酮水平快速、持久控制在20ng/dL以下。
