Cancer Manag Res: 骨扫描能够指导二氯化镭-223治疗前列腺癌骨转移么?

2018-09-28 AlexYang MedSci原创

二氯化镭-223最近在美国被批准作为伴随骨转移去势难治性前列腺癌(mCRPC)的一种可利用的治疗选择。最近,有研究人员描述了在患者中使用Ra-223治疗中的经历和经验,并尝试优化患者对Ra-223治疗的选择,从而达到最好的治疗结果。研究总共包括了20名进行二氯Ra-223治疗的患者。12名患者具有大量的骨转移,3名患者进行了超级扫描,3名患者具有2到7个骨转移病灶。2名患者在第一次注射后跟踪调查丢

二氯化镭-223最近在美国被批准作为伴随骨转移去势难治性前列腺癌(mCRPC)的一种可利用的治疗选择。最近,有研究人员描述了在患者中使用Ra-223治疗中的经历和经验,并尝试优化患者对Ra-223治疗的选择,从而达到最好的治疗结果。

研究总共包括了20名进行二氯Ra-223治疗的患者。12名患者具有大量的骨转移,3名患者进行了超级扫描,3名患者具有2到7个骨转移病灶。2名患者在第一次注射后跟踪调查丢失。在FR组中包括8名患者,在UR组中包括10名患者。在UR组的患者的ECOG和NRS疼痛得分分别为1.3和5.0,在FR组中分别为0.8个4.4。UR组中平均的PSA和肌酐水平分别为445.2 ng/mL和1.2 mg/d,FR组中分别为22.7 ng/mL和11. mg/dL。另外,平均的血红蛋白、血小板和绝对中性粒细胞值在UR组中分别为11.2 g/dL, 314.9 K/cmm和7.3 K/cmm,在FR组中分别为 11.6 g/dL, 207.0 K/cmm和6.2 K/cmm。在FR组中,8名患者中的7名在治疗结束时进行了骨扫描,其中5名患者具有改善。在1名患者中出现了混合响应,在另1名患者中出现了疾病的恶化。在UR组中,5名患者完成了5到6次的注射并且进行了骨扫描,结果表明出现了骨转移斑,其中1名患者恶化,1名患者得到了改善。3名UR组的还咋在第一次或者第二次注射后死亡。这些患者中的2名进行了基础的超级扫描,1名进行了扩展的骨转移扫描。

最后,研究人员指出,具有低PSA水平和更少骨转移病灶的mCRPC患者更可能对二氯化Ra-223治疗产生有利响应。
