Abstract

The anthracycline anticancer agent doxorubicin has long been recognized to induce a dose-limiting cardiotoxicity and may be associated with genes relevant to doxorubicin disposition. Recent reports suggest a role for a number of single nucleotide polymorphisms in anthracycline cardiotoxicity in children. We describe two adult sisters with anthracycline cardiotoxicity that developed after a relatively low dose of doxorubicin. One sister carried the variant genotype for histamine N-ethyl transferase (HNMT, rs17583889) while the other was heterozygous, suggesting a similar role for these genotypes in adults with anthracycline cardiotoxicity. Although this requires further study, these genotypes may be important in the clinical dosing, or use of the liposomal formulation of doxorubicin.

摘要

蒽环类抗癌药物阿霉素长期以来被认为会引起剂量限制性心脏毒性,并且可能与阿霉素代谢相关基因有关。最近的报告表明,一些单核苷酸多态性在儿童蒽环类心脏毒性中起作用。我们描述了两名成年姐妹,她们在接受相对低剂量的阿霉素后出现了蒽环类心脏毒性。其中一名姐妹携带组胺N-乙基转移酶(HNMT,rs17583889)的变异基因型,而另一名是杂合子,这表明这些基因型在成年蒽环类心脏毒性患者中可能起类似作用。尽管这需要进一步研究,但这些基因型在阿霉素临床给药或脂质体制剂的使用中可能很重要。
