The applicability of established clinical and histopathological risk factors for tumor recurrence during long-term postoperative care in meningioma patients.
Risk factors to predict late-onset tumor recurrence in meningioma patients are urgently needed to schedule control intervals during long-term follow-up. We therefore analyzed the value of established risk factors for postoperative meningiom…

Predicting postoperative seizure development in meningiomas - Analyses of clinical, histological and radiological risk factors.
[INTRODUCTION] Seizures after meningioma surgery are common, with a distinct impact on postoperative life quality. Sufficient risk factors for seizure development are sparsely known but needed to improve perioperative patient counseling and…

Risk of tumor recurrence in intracranial meningiomas: comparative analyses of the predictive value of the postoperative tumor volume and the Simpson classification.
[OBJECTIVE] In meningiomas, the Simpson grading system is applied to estimate the risk of postoperative recurrence, but might suffer from bias and limited overview of the resection cavity. In contrast, the value of the postoperative tumor v…

The Simpson grading: defining the optimal threshold for gross total resection in meningioma surgery.
Classification of the extent of resection into gross and subtotal resection (GTR and STR) after meningioma surgery is derived from the Simpson grading. Although utilized to indicate adjuvant treatment or study inclusion, conflicting definit…

Brain invasion in meningiomas: does surgical sampling impact specimen characteristics and histology?
Brain invasion (BI) is a new criterion for atypia in meningiomas and therefore potentially impacts adjuvant treatment. However, it remains unclear whether surgical practice and specimen characteristics influence histopathological analyses a…

Real-time in vivo kinetics of protoporphyrin IX after administration of 5-aminolevulinic acid in meningiomas and comparative analyses with glioblastomas.
[BACKGROUND] The usefulness of 5-aminolevulinic acid (5-ALA)-mediated fluorescence-guided surgery (FGS) in meningiomas is intensely discussed. However, data about kinetics of 5-ALA and protoporphyrin (Pp) IX in meningiomas are lacking. [ME…
