Clinical, statistical and diagnostic features of relapse and continued growth of intracranial meningiomas

Introduction. Meningiomas account for 18–34 % of all intracranial tumors in adults and are the second most common among all intracranial neoplasms. Recurrence and progression account for 25 %, on average, even after radical tumor resection and radiotherapy., that worsens the prognosis and functional outcome of the disease significantly. Clinical manifestations often occur with large tumor sizes, initial symptoms are not taken into account by patients and by doctors during follow-up after surgery. Purpose. To assess the clinical features in patients with recurrence and progression of intracranial meningiomas and to identify the features of clinical manifestations in the progression of meningiomas. Materials and methods . The study was based on patients (132 cases) with recurrence and progression of intracranial meningiomas with Grade I–III according to histology, who were treated in the Department of Neurosurgery No. 4 of the Polenov Neurosurgical Institute in the period of time from 2014 to 2024. Assessment of clinical neurological symptoms was performed according to standard methods in clinical practice. The results were evaluated using the software system STATISTICA 10.0. Results. The multifactorial analysis of the clinical manifestations of the disease in recurrent intracranial meningiomas was performed, the main trends in oncogenesis were identified, and the most common clinical symptoms of tumor progression were identified, which must be taken into account by doctors during follow-up after surgery.
