Surgical Outcome of Patients With Supratentorial Meningiomas Aged 80 Years or Older

Neurosurgery 94:399–412, 2024

Demographic changes will lead to an increase in old patients, a population with significant risk of postoperative morbidity and mortality, requiring neurosurgery for meningiomas. This multicenter study aims to report neurofunctional status after resection of patients with supratentorial meningioma aged 80 years or older, to identify factors associated with outcome, and to validate a previously proposed decision support tool.

METHODS: Neurofunctional status was assessed by the Karnofsky Performance Scale (KPS). Patients were categorized in poor (KPS ≤40), intermediate (KPS 50-70), and good (KPS ≥80) preoperative subgroups. Volumetric analyses of tumor and peritumoral brain edema (PTBE) were performed; volumes were scored as small (<10 cm3 ), medium (10-50 cm3 ), and large (>50 cm3 ).

RESULTS: The study population consisted of 262 patients, and the median age at surgery was 83.0 years. The median preoperative KPS was 70; 117 (44.7%) patients were allotted to the good, 113 (43.1%) to the intermediate, and 32 (12.2%) to the poor subgroup. The median tumor and PTBE volumes were 30.2 cm 3 and 27.3 cm3 ; large PTBE volume correlated with poor preoperative KPS status (P = .008). The 90-day and 1-year mortality rates were 9.0% and 13.2%, respectively. Within the first postoperative year, 101 (38.5%) patients improved, 87 (33.2%) were unchanged, and 74 (28.2%) were functionally worse (including deaths). Each year increase of age associated with 44% (23%-70%) increased risk of 90-day and 1-year mortality. In total, 111 (42.4%) patients suffered from surgery-associated complications. Maximum tumor diameter ≥5 cm (odds ratio 1.87 [1.12-3.13]) and large tumor volume (odds ratio 2.35 [1.01-5.50]) associated with increased risk of complications. Among patients with poor preoperative status and large PTBE, most (58.3%) benefited from surgery.

CONCLUSION: Patients with poor preoperative neurofunctional status and large PTBE most often showed postoperative improvements. The decision support tool may be of help in identifying cases that most likely benefit from surgery.

Is Eighty the New Sixty? Outcomes and Complications after Lumbar Decompression Surgery in Elderly Patients over 80 Years of Age

World Neurosurg. (2018) 112:e555-e560.

An increasing demographic aging of the general population results in a rising incidence of octogenarians and nonagenarians with spine disease. Patients older than 65 years represent the majority of patients with degenerative lumbar spine disease in our daily clinical routine. Surgical treatment is undertaken reluctantly because of an increased rate of comorbidities. We therefore assessed complication rates of lumbar decompression in regard to neurological outcome and medical conditions in patients age 80 years or older in a retrospective singlecenter series.

METHODS: Data for 244 patients (124 female, 120 male; mean age, 83.1  3 years; age range, 80e95 years) who underwent decompressive surgery for lumbar spinal stenosis or disc herniation between April 2007 and February 2016 were assessed retrospectively. Age at surgery, neurologic deficits (preoperative and postoperative), relevant medical comorbidities and previous lumbar decompression, intraoperative and postoperative complications (e.g., surgery-related, medical), duration of surgery, length of hospital stay, and rate of revision surgeries were recorded.

RESULTS: Surgery was performed for lumbar stenosis (184 patients; 75.4%), lumbar disc herniation (13 patients; 5.3%) or both (47 patients; 19.3%). Seventy-six patients (31.3%) patients experienced preoperative neurologic deficits; 48 (63.2%) of these patients improved, 28 (36.8%) of them were unchanged after surgery, and none deteriorated. New transient, postoperative, neurologic deficits occurred in 6 patients (2.5%). All 55 (22.5%) intraoperative complications were mild to moderate, and no severe surgical complications occurred. Two hundred fifteen patients (88%) had relevant medical disorders. Nineteen (7.7%) postoperative medical complications were reported in 17 patients (7%), of which 14 (73.7%) were severe and 5 (26.3%) were mild (4 pulmonary embolisms, 6 pneumonias, 3 myocardial infarctions, 1 postoperative renal failure, 5 urinary tract infections). Medical complications that necessitated intensive care unit treatment and resulted in lethal outcome were seen in 2 patients (0.8%).

CONCLUSION: Despite their age, the vast majority of octogenarians and nonagenarians benefited from lumbar decompression surgery. Mild to moderate intraoperative complications were relatively frequent, whereas severe intraoperative complications did not occur. The majority of medical complications was severe, but the incidence was acceptable, and the postoperative outcome was still favorable in most patients
