Abstract

Meningioma accounts for more than 30% of all intracranial tumours. It affects mainly the elderly above the age of 60, at a female:male ratio of 3:2. The prognosis is variable: it is usually favourable with no progression in tumour grade and no recurrence in WHO grade 1 tumours. However, a minority of tumours represent atypical (grade 2) or anaplastic (grade 3) meningiomas; this heterogeneity is also reflected in histopathological appearances. Irrespective of the grade, the size of the tumour and the localisation may have severe, sometimes lethal consequences. Following neurosurgical interventions to remove the tumour, recurrence and progression in WHO grade may occur. Our knowledge on predisposing histomorphological and molecular factors of recurrence is rather limited. These can be classified as I) demographic II) environmental, III) genetic and epigenetic IV) imaging, V) neuropathological, and VI) neurosurgical. In view of the complex background of tumour recurrence, the recognition of often subtle signs of increased risk of recurrence requires close collaboration of experts from several medical specialties. This multidisciplinary approach results in better therapy and fewer complications related to tumour recurrence.

摘要

脑膜瘤占所有颅内肿瘤的30%以上。它主要影响60岁以上的老年人,女性与男性的比例为3:2。预后各不相同:通常良好,肿瘤分级无进展,世界卫生组织(WHO)1级肿瘤无复发。然而,少数肿瘤为非典型(2级)或间变性(3级)脑膜瘤;这种异质性也反映在组织病理学表现中。无论肿瘤分级如何,其大小和位置都可能产生严重后果,有时甚至是致命的。在进行神经外科手术切除肿瘤后,WHO分级的肿瘤可能会复发和进展。我们对导致复发的组织形态学和分子因素的了解相当有限。这些因素可分为:I)人口统计学因素;II)环境因素;III)遗传和表观遗传因素;IV)影像学因素;V)神经病理学因素;VI)神经外科因素。鉴于肿瘤复发的复杂背景,识别往往细微的复发风险增加迹象需要多个医学专业的专家密切合作。这种多学科方法可带来更好的治疗效果,并减少与肿瘤复发相关的并发症。
