BACKGROUND:One of the goals of cancer treatment is symptoms management especially at the end stage. The common symptoms in cancer include pain, fatigue, depression and cognitive dysfunction. The available treatment options for symptom management are limited. Methylphenidate, a psychostimulant, may be of benefit for these patients. In this report, we review the use of methylphenidate for symptoms control in cancer patients. METHOD:Electronic literature search on PubMed was conducted using the following keywords: methylphenidate, cancer, carcinoma, oncology, oncological and tumour. We identified forty two relevant studies and publications on the use of methylphenidate in cancer patients to be included in this review. RESULTS:Methylphenidate was found to have some evidence in reducing opioid-induced sedation, improving cognitive symptoms and reduction of fatigue in cancer patients. Nevertheless, the results were inconsistent due to variations in the study populations, study design and outcome measures, among others. There was minimal evidence on its use in treating depression. Otherwise, methylphenidate was generally well-tolerated by patients. CONCLUSION:This review potentially supports the use of methylphenidate for opioid-induced sedation, cognitive decline and fatigue in cancer patients. Further placebo-controlled trials would help in strengthening the evidence for this treatment.

背景:癌症治疗的目标之一是症状管理,尤其是在末期。癌症的常见症状包括疼痛,疲劳,抑郁和认知功能障碍。症状管理的可用治疗方法有限。哌醋甲酯是一种精神刺激药,可能对这些患者有益。在本报告中,我们回顾了哌醋甲酯在癌症患者中控制症状的用途。
方法:使用以下关键词在PubMed上进行电子文献检索:哌醋甲酯,癌症,癌,肿瘤学,肿瘤学和肿瘤。我们确定了四十二项有关在癌症患者中使用哌醋甲酯的相关研究和出版物,这些都包括在本评价中。
结果:哌醋甲酯被发现在减少阿片类药物引起的镇静,改善认知症状和减轻癌症患者的疲劳方面有一些证据。然而,由于研究人群,研究设计和结果测量等方面的差异,结果不一致。几乎没有证据表明其可用于治疗抑郁症。否则,患者通常耐受哌醋甲酯。
结论:本评价潜在地支持使用哌醋甲酯治疗阿片类药物引起的镇静,认知能力下降和癌症患者的疲劳。进一步的安慰剂对照试验将有助于加强这种治疗的证据。
