Cerebral edema from brain tumors can cause neurological impairment. Steroids treat edema but with possible adverse effects. We surveyed providers regarding steroid use in newly diagnosed patients with brain tumors to determine if practices are standard or markedly variable.
An anonymous voluntary online survey was sent to members of neuro-oncology consortiums. Four clinical scenarios were provided and questions regarding initiation of steroids, type, dose, formulation, and duration were asked. Demographic information was collected.
369 providers received the survey, 76 responded (20.6% response rate). The proportion of providers who would start steroids significantly differed among scenarios (scenario 1 vs 2, p < 0.001; 2 vs 3, p < 0.001; 1 vs 3, p < 0.001). 75 (98.7%) providers would start steroids for vasogenic edema (scenario 1) and 55 (72.4%) for obstructive hydrocephalus (scenario 2). 16 (21.1%) would start steroids for vasogenic edema but not obstructive hydrocephalus. The odds of choosing to start steroids in patients with obstructive hydrocephalus were 7.59 times more (95% CI: 2.29, 25.13) if providers felt symptoms would improve within 24 h. All would use dexamethasone. A significant difference was seen between the proportion of providers who would give a loading dose if vasogenic edema with neurological deficits were noted versus vasogenic edema alone (57.9% vs 43.4%; p = 0.002).
These results suggest that providers recommend dexamethasone for patients with vasogenic edema and obstructive hydrocephalus. Variability remains with dosing schedule. Further studies are needed to identify the most appropriate use of steroids for newly diagnosed CNS tumor patients with the goal to create steroid management guidelines.
脑肿瘤引起的脑水肿可导致神经功能障碍。类固醇可治疗水肿,但可能有不良反应。我们调查了肿瘤患者新诊断后使用类固醇的情况,以确定实践是否标准或差异很大。
向神经肿瘤学联盟的成员发送了一份匿名自愿在线调查。提供了四个临床情况,并询问了开始使用类固醇的问题、类型、剂量、剂型和持续时间。收集了人口统计学信息。
369 名提供者收到了调查,76 名(20.6%的回复率)做出了回应。启动类固醇治疗的提供者比例在不同情况下有显著差异(情况 1 与 2 相比,p<0.001;2 与 3 相比,p<0.001;1 与 3 相比,p<0.001)。75 名(98.7%)提供者会为血管源性水肿(情况 1)和 55 名(72.4%)为梗阻性脑积水(情况 2)开始使用类固醇。16 名(21.1%)会为血管源性水肿而不是梗阻性脑积水开始使用类固醇。如果提供者认为症状会在 24 小时内改善,那么为梗阻性脑积水患者选择开始使用类固醇的可能性是前者的 7.59 倍(95%CI:2.29,25.13)。所有提供者都会使用地塞米松。如果出现伴有神经功能缺损的血管源性水肿与单纯血管源性水肿,给予负荷剂量的提供者比例有显著差异(57.9%比 43.4%;p=0.002)。
这些结果表明,提供者建议对血管源性水肿和梗阻性脑积水患者使用地塞米松。在剂量方案方面仍然存在差异。需要进一步研究以确定新诊断的中枢神经系统肿瘤患者使用类固醇的最佳方法,以制定类固醇管理指南。
