Background:
Spinal meningiomas are benign and slow-growing intradural tumors. Surgery is the choice of treatment. In this retrospective study, results of minimally invasive Simpson grade 2 resection and its impact on recurrence in 44 spinal meningiomas are reviewed.
Methods:
Clinical data of 44 cases who underwent surgery for spinal meningiomas between 2010 and 2020 have been reviewed retrospectively. Demographics, preoperative and postoperative clinical states, pathologic type, location of the meningioma relative to the spinal cord, resection amount of the tumor according to Simpson's grading scale, postoperative complications, recurrence rate, and correlation between preoperative and intraoperative data and recurrence were analyzed.
Results:
The tumor was located in the thoracic spine in 31 cases, in the cervical spine in 12 cases, and in the lumbar spine in one case. Dural attachment of tumor was ventral to the spinal cord in 15 cases, lateral to the spinal cord in 15 cases, and posterior to the spinal cord in 14 cases. All cases underwent microsurgical Simpson grade 2 resection. Two cases were recurrent and reoperated. Recurrences were observed in cases younger than 18 years old, in cervical spines and in cases with long dural tails.
Conclusions:
Simpson grade 2 resection is safe and effective in spinal meningiomas. Patients younger than 18 year old, and those with cervical location and long dural tail may be under risk of recurrence after Simpson grade 2 resection.
Insights
Minimally invasive Simpson grade 2 resection is effective for spinal meningiomas. However, younger patients, cervical tumors, and long dural tails may increase recurrence risk after this surgery.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Spinal meningiomas are slow-growing, benign intradural tumors.
- Surgical resection is the primary treatment modality.
- This study evaluates minimally invasive Simpson grade 2 resection for spinal meningiomas.
Purpose of the Study:
- To review the outcomes of Simpson grade 2 resection in 44 spinal meningioma cases.
- To assess the impact of this surgical technique on tumor recurrence.
- To identify factors correlating with recurrence after resection.
Main Methods:
- Retrospective review of clinical data from 44 patients (2010-2020).
- Analysis included demographics, tumor characteristics, Simpson grade 2 resection details, and recurrence rates.
- Correlation of pre-operative and intra-operative factors with recurrence was examined.
Main Results:
- 31 thoracic, 12 cervical, and 1 lumbar meningioma cases were analyzed.
- Simpson grade 2 resection was performed in all cases.
- Recurrence was observed in 2 cases, associated with younger age (<18), cervical location, and long dural tails.
Conclusions:
- Simpson grade 2 resection is a safe and effective surgical approach for spinal meningiomas.
- Patients under 18, with cervical tumors, or long dural tails are at higher risk for recurrence.
- Further investigation into risk stratification and tailored treatment may be warranted.
