Do steroids improve neurologic symptoms in patients with metastatic brain tumors compared to no treatment? If steroids are given, what dose should be used? Comparisons include: (1) steroid therapy versus none. (2) comparison of different doses of steroid therapy.
These recommendations apply to adults diagnosed with brain metastases.
Steroid therapy versus no steroid therapy Asymptomatic brain metastases patients without mass effect Insufficient evidence exists to make a treatment recommendation for this clinical scenario. Brain metastases patients with mild symptoms related to mass effect Level 3 Corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. It is recommended for patients who are symptomatic from metastatic disease to the brain that a starting dose of 4-8 mg/day of dexamethasone be considered. Brain metastases patients with moderate to severe symptoms related to mass effect Level 3 Corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. If patients exhibit severe symptoms consistent with increased intracranial pressure, it is recommended that higher doses such as 16 mg/day or more be considered. Choice of Steroid Level 3 If corticosteroids are given, dexamethasone is the best drug choice given the available evidence. Duration of Corticosteroid Administration Level 3 Corticosteroids, if given, should be tapered slowly over a 2 week time period, or longer in symptomatic patients, based upon an individualized treatment regimen and a full understanding of the long-term sequelae of corticosteroid therapy. Given the very limited number of studies (two) which met the eligibility criteria for the systematic review, these are the only recommendations that can be offered based on this methodology.

与不治疗相比,类固醇是否能改善转移性脑肿瘤患者的神经症状?如果使用类固醇,应使用何种剂量?包括以下比较:(1)类固醇治疗与无治疗。(2)不同剂量类固醇治疗的比较。
这些建议适用于被诊断患有脑转移瘤的成年人。
类固醇治疗与无类固醇治疗
无症状性脑转移瘤患者,无肿块效应
缺乏证据支持这种临床情况的治疗建议。
轻度症状与肿块效应相关的脑转移瘤患者
3 级 皮质类固醇建议用于暂时缓解与脑转移瘤相关的颅内压增高和水肿引起的症状。建议对有脑转移瘤相关症状的患者考虑起始剂量为 4-8mg/天地塞米松。
中度至重度症状与肿块效应相关的脑转移瘤患者
3 级 皮质类固醇建议用于暂时缓解与脑转移瘤相关的颅内压增高和水肿引起的症状。如果患者表现出与颅内压升高一致的严重症状,建议考虑更高剂量,如 16mg/天或更高。
类固醇的选择
3 级 如果给予皮质类固醇,根据现有证据,地塞米松是最佳药物选择。
皮质类固醇的给药持续时间
3 级 如果给予皮质类固醇,应在 2 周内逐渐减少剂量,或在有症状的患者中根据个体化治疗方案和充分了解皮质类固醇治疗的长期后果延长剂量。由于只有两项符合系统评价纳入标准的研究数量非常有限,因此只能根据这种方法提供这些建议。请参阅“讨论”和“总结”部分以获取更多详细信息。
