Colorectal cancer is currently a public health priority because it is the second leading cause of cancer deaths in Western countries. Combination regimes of oxaliplatin and infusional fluorouracil/leucovorin or capecitabine have emerged as important options in the palliative and adjuvant treatment of colorectal cancer. Although better tolerated than cisplatin, oxaliplatin displays a characteristic profile of adverse events whose recognition and management are essential for physicians who treat patients with colorectal cancer and other malignancies that benefit from the use of oxaliplatin. Peripheral neuropathy is probably the most frequent and clinically relevant adverse event associated with the use of oxaliplatin, and several measures have been proposed to mitigate this toxicity. Temporary interruption of oxaliplatin before limiting neurotoxicity develops during therapy is a potential approach to avoid the problem of oxaliplatin-associated neuropathy in patients with metastatic colorectal cancer. Calcium and magnesium infusions have no effect on chemotherapy efficacy and also constitute a useful approach in clinical practice. Finally, the incidence and severity of chronic peripheral neuropathy in patients treated with oxaliplatin may be reduced by the use of neuroprotective agents, for example, venlafaxine. Other adverse events, such as gastrointestinal and liver toxicity, thrombocytopenia, and hypersensitivity reactions, are also reviewed in this article, and suggestions are made for their management.
结直肠癌目前是公共卫生重点,因为它是西方国家癌症死亡的第二大主要原因。奥沙利铂联合氟尿嘧啶/亚叶酸或卡培他滨的联合方案已成为结直肠癌姑息治疗和辅助治疗的重要选择。虽然奥沙利铂的耐受性优于顺铂,但它具有独特的不良事件特征,对于治疗结直肠癌和其他受益于奥沙利铂的恶性肿瘤的医生来说,识别和管理这些不良事件至关重要。周围神经病变可能是与奥沙利铂使用相关的最常见和最具临床意义的不良事件,已经提出了几种减轻这种毒性的措施。在治疗过程中限制神经毒性发展之前暂时中断奥沙利铂的使用是避免转移性结直肠癌患者奥沙利铂相关神经病变问题的一种潜在方法。钙和镁输液对化疗疗效没有影响,在临床实践中也是一种有用的方法。最后,神经保护剂如文拉法辛的使用可能会降低接受奥沙利铂治疗的患者慢性周围神经病变的发生率和严重程度。本文还回顾了其他不良事件,如胃肠道和肝脏毒性、血小板减少症和过敏反应,并对其管理提出了建议。
