Research Objective: To examine the association of pathohistological type of meningiomas with Ki-67 index values, recurrence rates, and treatment outcomes. To investigate differences in treatment outcomes and complication rates based on pathohistological type, Ki-67 index value, and type of neurosurgical treatment. To assess whether there are differences in mRS questionnaire scores before and after neurosurgical treatment. Study Design: Prospective study using historical data. Participants and Methods: The study included patients with pathohistologically verified spinal meningiomas who underwent surgery at the Department of Neurosurgery, Clinical Hospital Center Osijek, from 1990 - 2023. Patient data collected included age and gender, type of preoperative diagnostics, clinical presentation, tumor localization by region, type of neurosurgical approach to the spinal canal, extent of surgical procedure, type and frequency of surgical complications, pathohistological type and WHO grade, Ki-67 index value, clinical status before and after surgery, recurrence rates, treatment modalities for recurrences, and clinical outcomes after recurrence treatment. Results: No statistically significant difference was observed in Ki-67 index and WHO grade comparison (Mann-Whitney U test, P > 0.05). There was no significant difference in the type of diagnostics (Fisher's exact test, P > 0.05), neurosurgical approach (P > 0.05), extent of neurosurgical procedure (P > 0.05), surgical complications (P > 0.05), and recurrences (P > 0.05) based on meningioma pathohistological type. The median mRS before the intervention was 4 (3-5), and after the intervention, it was 3 (1.5-3.5) (Wilcoxon signed-rank test, P < 0.001). Conclusion: No statistically significant association was observed in the first two objectives. However, a statistically significant difference was found in mRS scores before and after neurosurgical intervention.
