Xeroderma pigmentosum (XP) is a genetic disease in which DNA repair mechanisms are impaired. Cisplatin (CDDP) exerts cytotoxic effects by forming mainly intrastrand DNA cross-links, and sensitivity to CDDP depends on the DNA repair system. Several in vitro studies have suggested that treatment with CDDP may cause enhanced adverse events as well as anti-tumor activity in cancer patients with XP. This article is the first to describe two cancer patients with XP showing severe adverse events following CDDP-based chemotherapy. Physicians should pay attention when administering CDDP in cancer patients with XP.
着色性干皮病(XP)是一种DNA修复机制受损的遗传性疾病。顺铂(CDDP)主要通过形成链内DNA交联发挥细胞毒性作用,对CDDP的敏感性取决于DNA修复系统。多项体外研究表明,对于患有XP的癌症患者,使用CDDP治疗可能会导致不良事件增加以及抗肿瘤增强以及抗肿瘤活性。本文首次描述了两名患有XP的癌症患者在接受基于CDDP的化疗后出现严重不良事件。医生在给患有XP的癌症患者使用CDDP时应予以注意。
