Health-Related Quality of Life Outcomes in Meningioma Patients Based upon Tumor Location and Treatment Modality: A Systematic Review and Meta-Analysis

SIMPLE SUMMARY: We provide the first comprehensive systematic review and meta-analysis examining the impact of tumor location and treatment modalities on health-related quality of life (HRQoL) in patients with meningioma. We systematically reviewed HRQoL outcomes for non-skull base meningiomas (NSBMs), anterior, middle, and posterior fossa skull base meningiomas (SBMs) following neurosurgical and/or radiotherapeutic intervention. The literature was searched for studies that investigated HRQoL following surgical resection, radiosurgery, or radiotherapy and was analyzed to reveal HRQoL outcomes based on tumor location. With regard to therapeutic intervention, craniotomy was associated with significantly higher improvements in postoperative Karnofsky Performance Status (KPS) scores following treatment of anterior/middle skull base meningiomas (SBMs) in comparison to posterior SBMs. The authors further investigate factors that may impact HRQoL and the occurrence of postoperative neurological deficits. Due to a lack of consensus on the use of standardized quantitative tools to measure HRQoL, results are difficult to compare within the literature. We therefore provide recommendations on the utility of pertinent HRQoL instruments based upon skull base region and treatment modality. ABSTRACT: Patients with meningiomas may have reduced health-related quality of life (HRQoL) due to postoperative neurological deficits, cognitive dysfunction, and psychosocial burden. Although advances in surgery and radiotherapy have improved progression-free survival rates, there is limited evidence regarding treatment outcomes on HRQoL. This review examines HRQoL outcomes based on tumor location and treatment modality. A systematic search in PubMed yielded 28 studies with 3167 patients. The mean age was 54.27 years and most patients were female (70.8%). Approximately 78% of meningiomas were located in the skull base (10.8% anterior, 23.3% middle, and 39.7% posterior fossae). Treatment modalities included craniotomy (73.6%), radiotherapy (11.4%), and endoscopic endonasal approach (EEA) (4.0%). The Karnofsky Performance Scale (KPS) was the most commonly utilized HRQoL instrument (27%). Preoperative KPS scores > 80 were associated with increased occurrence of postoperative neurological deficits. A significant difference was found between pre- and post-operative KPS scores for anterior/middle skull base meningiomas (SBMs) in comparison to posterior (SBMs) when treated with craniotomy. Post-craniotomy SF-36 scores were lower for posterior SBMs in comparison to those in the anterior and middle fossae. Risk factors for poor neurological outcomes include a high preoperative KPS score and patients with posterior SBMs may experience a greater burden in HRQoL.
