To review state of art and relevant advances in the molecular genetics and management of ependymomas of children and adults.
Ependymomas may occur either in the brain or in the spinal cord. Compared with intracranial ependymomas, spinal ependymomas are less frequent and exhibit a better prognosis. The new WHO classification of CNS tumors of 2021 has subdivided ependymomas into different histomolecular subgroups with different outcome. The majority of studies have shown a major impact of extent of resection; thus, a complete resection must be performed, whenever possible, at first surgery or at reoperation. Conformal radiotherapy is recommended for grade 3 or incompletely resected grade II tumors. Proton therapy is increasingly employed especially in children to reduce the risk of neurocognitive and endocrine sequelae. Craniospinal irradiation is reserved for metastatic disease. Chemotherapy is not useful as primary treatment and is commonly employed as salvage treatment for patients failing surgery and radiotherapy. Standard treatments are still the mainstay of treatment: the discovery of new druggable pathways will hopefully increase the therapeutic armamentarium in the near future.
回顾儿童和成人室管膜瘤的分子遗传学和治疗的最新进展。
室管膜瘤可发生在脑内或脊髓内。与颅内室管膜瘤相比,脊髓室管膜瘤发病率较低,预后较好。2021 年版世界卫生组织中枢神经系统肿瘤分类将室管膜瘤细分为不同的组织分子亚群,具有不同的预后。大多数研究表明,肿瘤切除范围有重要影响;因此,只要有可能,第一次手术或再次手术时必须进行完全切除。对于 3 级或未完全切除的 2 级肿瘤,推荐使用适形放疗。质子治疗越来越多地用于儿童,以降低神经认知和内分泌后遗症的风险。颅脊髓照射保留用于转移性疾病。化疗不作为初始治疗有用,通常作为手术和放疗失败患者的挽救治疗。标准治疗仍然是治疗的主要方法:新的可治疗途径的发现有望在不久的将来增加治疗手段。
