Cisplatin is a commonly used chemotherapeutic agent with proven efficacy in treating various malignancies, including testicular, ovarian, cervical, breast, bladder, head and neck, and lung cancer. Cisplatin is also used to treat tumors in children, such as neuroblastoma, osteosarcoma, and hepatoblastoma. However, its clinical use is limited by severe side effects, including ototoxicity, nephrotoxicity, neurotoxicity, hepatotoxicity, gastrointestinal toxicity, and retinal toxicity. Cisplatin-induced ototoxicity manifests as irreversible, bilateral, high-frequency sensorineural hearing loss in 40-60% of adults and in up to 60% of children. Hearing loss can lead to social isolation, depression, and cognitive decline in adults, and speech and language developmental delays in children. Cisplatin causes hair cell death by forming DNA adducts, mitochondrial dysfunction, oxidative stress, and inflammation, culminating in programmed cell death by apoptosis, necroptosis, pyroptosis, or ferroptosis. Contemporary medical interventions for cisplatin ototoxicity are limited to prosthetic devices, such as hearing aids, but these have significant limitations because the cochlea remains damaged. Recently, the U.S. Food and Drug Administration (FDA) approved the first therapy, sodium thiosulfate, to prevent cisplatin-induced hearing loss in pediatric patients with localized, non-metastatic solid tumors. Other pharmacological treatments for cisplatin ototoxicity are in various stages of preclinical and clinical development. This narrative review aims to highlight the molecular mechanisms involved in cisplatin-induced ototoxicity, focusing on cochlear inflammation, and shed light on potential antioxidant and anti-inflammatory therapeutic interventions to prevent or mitigate the ototoxic effects of cisplatin. We conducted a comprehensive literature search (Google Scholar, PubMed) focusing on publications in the last five years.
顺铂是一种常用的化疗药物,已被证明在治疗多种恶性肿瘤方面具有疗效,包括睾丸癌、卵巢癌、宫颈癌、乳腺癌、膀胱癌、头颈部癌和肺癌。顺铂也用于治疗儿童肿瘤,如神经母细胞瘤、骨肉瘤和肝母细胞瘤。然而,其临床应用受到严重副作用的限制,包括耳毒性、肾毒性、神经毒性、肝毒性、胃肠道毒性和视网膜毒性。顺铂引起的耳毒性表现为成年人中有 40-60%、儿童中有高达 60%出现不可逆的双侧高频感音神经性听力损失。听力损失可导致成年人社交孤立、抑郁和认知能力下降,儿童出现言语和语言发育迟缓。顺铂通过形成 DNA 加合物、线粒体功能障碍、氧化应激和炎症导致毛细胞死亡,最终通过细胞凋亡、坏死性凋亡、细胞焦亡或铁死亡导致程序性细胞死亡。目前针对顺铂耳毒性的医学干预措施仅限于助听等修复装置,但这些措施存在显著局限性,因为耳蜗仍然受损。最近,美国食品和药物管理局(FDA)批准了第一种疗法,即硫代硫酸钠,用于预防局部非转移性实体肿瘤的儿科患者接受顺铂治疗时发生听力损失。其他针对顺铂耳毒性的药物治疗正在临床前和临床开发的各个阶段。本综述旨在强调顺铂诱导的耳毒性的分子机制,重点关注耳蜗炎症,并探讨潜在的抗氧化和抗炎治疗干预措施,以预防或减轻顺铂的耳毒性作用。我们进行了全面的文献检索(Google Scholar、PubMed),重点关注过去五年的出版物。
