Oral squamous cell carcinoma (OSCC) is a crucial public health problem, accounting for approximately 2% of all cancers globally and 90% of oral malignancies over the world. Unfortunately, despite the achievements in surgery, radiotherapy, and chemotherapy techniques over the past decades, OSCC patients still low 5-year survival rate. Cisplatin, a platinum-containing drug, serves as one of the first-line chemotherapeutic agents of OSCC. However, the resistance to cisplatin significantly limits the clinical practice and is a crucial factor in tumor recurrence and metastasis after conventional treatments. Ferroptosis is an iron-based form of cell death, which is initiated by the intracellular accumulation of lipid peroxidation and reactive oxygen species (ROS). Interestingly, cisplatin-resistant OSCC cells exhibit lower level of ROS and lipid peroxidation compared to sensitive cells. The reduced ferroptosis in cisplatin resistance cells indicates the potential relationship between cisplatin resistance and ferroptosis, which is proved by recent studies showing that in colorectal cancer cells. However, the modulation pathway of ferroptosis reversing cisplatin resistance in OSCC cells still remains unclear. This article aims to concisely summarize the molecular mechanisms and evaluate the relationship between ferroptosis and cisplatin resistance OSCC cells, thereby providing novel strategies for overcoming cisplatin resistance and developing new therapeutic approaches.
口腔鳞状细胞癌(OSCC)是一个关键的公共卫生问题,约占全球所有癌症的2%,占全球口腔恶性肿瘤的90%。不幸的是,尽管在过去几十年里手术、放疗和化疗技术取得了进展,但OSCC患者的5年生存率仍然很低。顺铂是一种含铂药物,是OSCC的一线化疗药物之一。然而,对顺铂的耐药性显著限制了临床应用,并且是传统治疗后肿瘤复发和转移的关键因素。铁死亡是一种基于铁的细胞死亡形式,由细胞内脂质过氧化和活性氧(ROS)的积累引发。有趣的是,与敏感细胞相比,顺铂耐药的OSCC细胞表现出较低水平的ROS和脂质过氧化。顺铂耐药细胞中铁死亡的减少表明了顺铂耐药与铁死亡之间的潜在关系,最近在结肠癌细胞中的研究证明了这一点。然而,铁死亡逆转OSCC细胞中顺铂耐药的调节途径仍不清楚。本文旨在简要总结分子机制,评估铁死亡与顺铂耐药OSCC细胞之间的关系,从而为克服顺铂耐药和开发新的治疗方法提供新策略。
