Intracranial meningioma surgery in the elderly (over 65 years): prognostic factors and outcome

Tuberculum Sellae Meningiomas

Acta Neurochir 157 (9): 1549-1557

Meningiomas are more prevalent in elderly individuals; however, the surgical outcome and prognostic factors in this age group are unclear. This retrospective study aimed to identify the prognostic factors of elderly patients with intracranial meningiomas who underwent surgical resection.

Methods

Eighty-six patients (aged ≥65) diagnosed with an intracranial meningioma were surgically treated at our department. The clinical, radiological, and follow-up data were retrospectively reviewed. Univariate and multivariate logistic analyses were performed to identify relationships between factors [age, sex, neurological condition, concomitant disease, American Society of Anesthesiology (ASA) classification, preoperative Karnofsky Performance Scale (KPS) score, tumor location and size, peritumoral edema, and Simpson resection grade] and outcome.

Results

One patient (1.2 %) died within 30 days of surgery. The morbidity rate was 37.2 %. Postoperative morbidities occurred more frequently in the patients with preoperative neurological deficits than in those without (p = 0.049). Univariate analysis identified significant relationships between a low KPS score (≤70) at discharge and preoperative neurological deficits, low preoperative KPS score (≤70), and critical tumor location (p < 0.001, p < 0.001, and p = 0.04, respectively). In the multivariate logistic analysis, only the preoperative KPS score remained significant for the KPS score at discharge (p = 0.005); there was no significant association with the most recent KPS score.

Conclusion

The outcome of intracranial meningioma resection in elderly individuals is favorable if the preoperative KPS score is >70 and no neurological deficits are present. Treatment decisions should be patient-specific, and additional factors should be considered when operations are performed in patients with a low preoperative KPS score or neurological deficits.

Transsphenoidal surgical treatment of pituitary adenomas in patients aged 80 years or older

Pituitary adenomas patients aged 80

Neurosurg Rev (2014) 37:269–277

To know the clinical characteristics of pituitary adenomas in the elderly patients aged 80 years or older who were surgically treated.

From1995 through 2012, 907 patients underwent surgery for the pituitary adenomas at Kagoshima and Hiroshima University hospitals in Japan. Ten (1.1 %) patients were aged 80 years or older. We retrospectively assessed the clinical characteristics including preoperative comorbidities, manifestations, neuroimaging findings, and endocrinologic features of these ten patients.

The subjects included eight males and two females. Their ages ranged from 80 to 86 with mean of 83.1 years. Of these, besides one case of growth hormone-producing adenoma, others were clinically nonfunctioning adenoma. Six patients had modest comorbidities such as hypertension, cardiovascular diseases, diabetes mellitus, or chronic kidney dysfunction, and all patients were classified into grade 2–3 on American Society of Anesthesiologists’ Physical Status grading. Transsphenoidal surgery was performed in all due to visual disturbance in eight, diabetes mellitus as an intercurrent illness of acromegaly in one, and for the purpose of preventing visual disturbance in one patient who had an adenoma impinging optic chiasm but still had normal visual field. The surgeries provided sufficient decompression of the optic pathways and improved visual disorder in all. In an acromegalic male, his comorbidities considerably improved. No permanent surgical morbidity ensued. More than three axes of anterior pituitary hormones were preoperatively impaired in all, which were rarely recovered.

Transsphenoidal surgery is safe and efficient treatment way for patients aged 80 years or older with pituitary adenomas with chiasmatic symptoms when the patients’ general condition is well preserved and pituitary hormonal deficiency is adequately replaced.

Delayed Neurological Deterioration After Mild Head Injury: Cause, Temporal Course, and Outcomes

acutesdh

Neurosurgery 73:753–760, 2013

Mild head injury (MHI) complicated by an intracranial hemorrhage (ICH) is a common cause of hospital admission after head trauma. Most patients are treated nonoperatively, remain neurologically stable, and are discharged uneventfully. However, a small percentage of patients suffer delayed neurological deterioration (DND). Little is known about the characteristics of DND after an MHI complicated by ICH.

OBJECTIVE: To identify the cause, temporal course, and outcomes of patients who deteriorated neurologically after presenting with MHI and ICH. METHODS: A retrospective review was performed of all adult patients presenting over 54 consecutive months with MHI and ICH. Patients who were treated nonoperatively after initial head computed tomography and had a subsequent DND (Glasgow Coma Scale score decrease $2) were identified. Demographics, neurological status, clinical course, radiographic findings, and outcome data were collected.

RESULTS: Over 54 months, 757 patients with MHI plus ICH were admitted for observation; of these, 31 (4.1%) experienced DND. Eighty-seven percent of patients deteriorated within 24 hours after admission. Twenty-one patients (68%) deteriorated as a result of progressive intracranial hemorrhage, and 10 patients (32%) deteriorated as a result of medical causes. Seven patients (23%) died. Variables significantly associated with mortality included age . 60 years, coagulopathy, and change in Marshall computed tomography classification.

CONCLUSION: The incidence of delayed neurological deterioration after MHI with ICH is low and usually occurs within 24 hours after admission. It results in significant morbidity and mortality if it is the result of progressive intracranial hemorrhage. Further research is needed to identify risk factors that can allow early detection and improve outcomes in these patients.

Glioblastoma therapy in the elderly and the importance of the extent of resection regardless of age

J Neurosurg 116:357–364, 2012. DOI: 10.3171/2011.8.JNS102114

The objective of this study was to analyze whether age influences the outcome of patients with glioblastoma and whether elderly patients with glioblastoma can tolerate the same aggressive treatment as younger patients.

Methods. Data from 361 consecutive patients with newly diagnosed cerebral glioblastoma (2000–2006) who underwent regular follow-up evaluation from initial diagnosis until death were prospectively entered into a database. Patients underwent resection (complete, subtotal, or partial) or biopsy, depending on tumor size, location, and Karnofsky Performance Scale score. Following surgery, all patients underwent adjuvant treatment consisting of radiotherapy, chemotherapy, or combined treatment. Patients older than 65 years of age were defined as elderly (146 total).

Results. Two hundred thirty-four patients underwent tumor resection (complete 26%, subtotal 29%, and partial 45%). One hundred twenty-seven underwent biopsy. Mean patient age was 61 years, and overall survival was 11.6 ± 12.1 months. The overall survival of elderly patients (9.1 ± 11.6 months) was significantly lower than that of younger patients (14.9 ± 16.7 months; p = 0.0001). Stratifying between resection or biopsy, age was a negative prognostic factor in patients undergoing biopsy (4.0 ± 7.1 vs 7.9 ± 8.7 months; p = 0.007), but not in patients undergoing tumor resection (13.0 ± 8.5 vs 13.3 ± 14.5 months; p = 0.86). Survival of elderly patients undergoing complete tumor resection was 17.7 ± 8.1 months.

Conclusions. In this series of patients with glioblastoma, age was a prognostic factor in patients undergoing biopsy, but not in patients undergoing resection. Tumor location and patient clinical status may prohibit extensive resection, but resection should not be withheld from patients only on the basis of age. In elderly patients with glioblastoma, undergoing resection to the extent feasible, followed by adjuvant therapies, is warranted.

Minimally Invasive Lumbar Interbody Fusion in Patients Older Than 70 Years of Age: Analysis of Peri- and Postoperative Complications

Neurosurgery 68:897–902, 2011 DOI: 10.1227/NEU.0b013e3182098bfa

The number of spine operations performed in the elderly population is rising.

OBJECTIVE: To identify and describe perioperative and postoperative complications in patients 70 years and older who have undergone minimally invasive lumbar interbody spine fusion.

METHODS: A retrospective analysis was performed on 66 consecutive patients aged 70 years or older who underwent a minimally invasive interbody lumbar fusion. Electronic medical records were analyzed for patient demographics, procedures, and perioperative and postoperative complications.

RESULTS: Between 2000 and 2009, 66 patients with an average age of 74.9 years (range, 70-86 years) underwent 68 lumbar interbody fusions procedures. The mean follow-up was 14.7 months (range, 1.5-50 months). The minimally invasive approaches included 41 cases of extreme lateral interbody fusion and 27 minimally invasive transforaminal lumbar interbody fusions. We observed 5 major (7.4%) and 17 minor (25%) complications. The 5 major complications consisted of 4 cases of interbody graft subsidence and 1 adjacent level disease. There were no intraoperative medical complications. There were no myocardial infarctions, pulmonary embolisms, hardware complications requiring removal, wound infections, major visceral, vascular, neural injuries, or death in the study period.

CONCLUSION: Minimally invasive interbody fusions can be performed in the elderly (ages 70 years and older) with an overall low rate of major complications. Graft subsidence in this population when not supplemented with posterior instrumentation is a concern. Age should not be a deterrent to performing complex minimally invasive interbody fusions in the elderly.

Chronic subdural hematoma in the elderly: not a benign disease

J Neurosurg 114:72–76, 2011. (DOI: 10.3171/2010.8.JNS10298)

Chronic subdural hematoma (CSDH) is perceived to be a “benign,” easily treated condition in the elderly, but reported follow-up periods are brief, usually limited to acute hospitalization.

Methods. The authors conducted a retrospective review of data obtained in a prospectively identified consecutive series of adult patients admitted to their institution between September 2000 and February 2008 and in whom there was a CT diagnosis of CSDH. Survival data were compared to life-table data.

Results. Of the 209 cases analyzed, 63% were men and the mean age was 80.6 years (range 65–96 years). Primary surgical interventions performed were bur holes in 21 patients, twist-drill closed-system drainage in 44, and craniotomies in 72. An additional 72 patients were simply observed. Reoperations were recorded in 5 patients—4 who had previously undergone twist-drill drainage and 1 who had previously undergone a bur hole procedure (p = 0.41, chi-square analysis). Thirty-five patients (16.7%) died in hospital, 130 were discharged to rehabilitation or a skilled care facility, and 44 returned home. The follow-up period extended to a maximum of 8.3 years (median 1.45 years). Six-month and 1-year mortality rates were 26.3% and 32%, respectively. In the multivariate analysis (step-wise logistic regression), the sole factor that predicted in-hospital death was neurological status on admission (OR 2.1, p = 0.02, for each step). Following discharge, the median survival in the remaining cohort was 4.4 years. In the Cox proportional hazards model, only age (hazard ratio [HR] 1.06/year, p = 0.02) and discharge to home (HR 0.24, p = 0.01) were related to survival, whereas the type of intervention, whether surgery was performed, size of subdural hematoma, amount of shift, bilateral subdural hematomas, and anticoagulant agent use did not affect the long- or short-term mortality rate. Comparison of postdischarge survival and anticipated actuarial survival demonstrated a markedly increased mortality rate in the CSDH group (median survival 4.4 vs 6 years, respectively; HR 1.94, p = 0.0002, log-rank test). This excess mortality rate was also observed at 6 months postdischarge with evidence of normalization only at 1 year.

Conclusions. In this first report of the long-term outcome of elderly patients with CSDH the authors observed persistent excess mortality up to 1 year beyond diagnosis. This belies the notion that CSDH is a benign disease and indicates it is a marker of other underlying chronic diseases similar to hip fracture

Glioblastoma multiforme of the elderly: the prognostic effect of resection on survival

J Neurooncol. DOI 10.1007/s11060-010-0429-9

According to recent developments the best treatment options for glioblastoma (GBM) consist in maximum safe resection and additional adjuvant treatment with radiotherapy (RT) and alkylating chemotherapy (CHX).

These options have been evaluated for populations with a median age of approximately 58 years. We therefore addressed the issue of whether elderly patients ([65years) could also benefit from cytoreductive surgery (CS) and adjuvant treatment using alkylating chemotherapy.

Onehundred and three patients suffering from newly diagnosed, primary supratentorial glioblastoma multiforme[65 years (median 70.8 years) were identified in our single-center glioma database (2002–2007) and retrospectively divided into group A (n = 31) treated with surgery alone (biopsy, BY, n = 21, CS n = 10), group B (n = 37) surgery plus radiation (BY n = 18, CS n = 19), and group C (n = 35) surgery, RT and CHX (BY n = 4, CS n = 31). Progression- free survival (PFS) and overall survival (OAS) were determined in each group and correlated to age, Karnofsky performance score (KPS), and extent of resection (biopsy (BY), partial (PR), and complete resection (CR)). Progression was defined according the Macdonald criteria. For all patients PFS and OAS were 3.2 months and 5.1 months (m) respectively. PFS and OAS for groups A/B/C were 1.8/ 3.2/6.4 m (P = 0.000) and 2.2/4.4/15.0 m (P = 0.000), respectively. Median age for groups A/B/C was 74.4/70.6/ 68.5 years and median KPS was 60/70/80. Age (\75, C75) was inversely correlated with OAS (5.8/2.5 m, P = 0.01). KPS (\70, C70) was correlated with OAS 2.4/6.5 m (P = 0.000). Extent of resection (BY, PR, or CR) correlated with PFS (2.1/3.4/6.4 m, P = 0,000) and OS (2.2/7.0/ 13.9 m, P = 0,000), respectively.

Our study shows that elderly GBM patients can benefit from maximum treatment procedures with cytoreductive microsurgery, radiation therapy, and chemotherapy. Treatment options are obviously affected by KPS and age. The most impressive outcome predictor in this population was the extent of microsurgical resection for patients treated with adjuvant radiotherapy and chemotherapy. To conclude, elderly GBM patients should not be per se excluded from intensive treatment procedures.

Management of Type II Odontoid Fractures in the Geriatric Population

J Spinal Disord Tech 2010;23:317–320

Objective: To analyze geriatric patients with Type II odontoid fractures treated either with rigid cervical orthosis (CO) or surgery (Odontoid Screw or Transarticular screw).

Summary of Background Data: Our literature search did not yield any studies on the outcome of Type II odontoid fractures in geriatric population treated with the rigid CO. We therefore designed a study to analyze geriatric patients with Type II odontoid fractures treated with either rigid cervical collar or surgery.

Materials and Methods: This is a retrospective chart review of patients with Type II odontoid fractures between July 1998 and June 2006. Inclusion criteria consists of males and females of 70 years of age or older with Type II odontoid fractures who were treated with rigid cervical collar or surgery. Exclusion criteria were displacement >4mm, posteriorly displaced fracture, neurologic compromise, multilevel cervical spine injury, and treatment in a halo vest. Medical comorbidities were assessed using the Modified Cumulative Illness Rating Scale for Geriatrics. Primary outcomes were mortality and fusion (union, stable nonunion, nonunion). Minimum of 3 months follow-up was acceptable.

Results: One hundred eighty four odontoid fractures were identified in 8 years. Twenty patients met our inclusion criteria (9 treated in rigid collar and 11 treated surgically). Median follow-up was 5.5 months. Out of 20 patients, 4 patients died (1 treated in CO, 3 treated surgically). Cumulative Illness Rating Scale for Geriatrics index was highest in patient treated in CO. In the rigid collar group, 6 patients had union (66.6%), and 2 developed stable nonunion (22.2%); whereas in the surgically treated group, 7 patients had union (87.5%), and 1 patient developed nonunion (12.5%).

Conclusions: Patients treated nonoperatively in rigid collar seem to have an overall favorable outcome. A well-designed prospective study, to compare the outcomes of surgical intervention with nonsurgical management of Type II odontoid in elderly is recommended

Interdisciplinary treatment of ruptured cerebral aneurysms in elderly patients

J Neurosurg 112:1200–1207, 2010. DOI: 10.3171/2009.10.JNS08754

The aim of the study was to assess postprocedural neurological deterioration and outcome in patients older than 70 years of age in whom treatment was managed in an interdisciplinary context.

Methods. This prospective longitudinal study included all patients 70 years of age or older treated for ruptured cerebral aneurysm over 10 years (June 1997–June 2007). The population was composed of 64 patients. The neurovascular interdisciplinary team jointly discussed the early obliteration procedure for each aneurysm. Neurological deterioration during the postprocedural 2 months and outcome at 6 months were assessed during consultation according to the modified Rankin Scale (mRS) as follows: favorable (mRS score ≤ 2) and unfavorable (mRS score > 2).

Results. Aneurysm sac obliteration was performed by microvascular clipping in 34 patients (53.1%) and by endovascular coiling in 30 (46.9%). Postprocedural neurological deterioration occurred in 30 patients (46.9%), related to ischemia in 19 (29.7%), rebleeding in 1 (1.6%), and hydrocephalus in 10 (15.6%). At 6 months, the outcome was favorable in 39 patients (60.9%). By multivariate regression logistic analysis, the independent factors associated with unfavorable outcome were age exceeding 75 years (p = 0.005), poor initial grade (p < 0.0001), and the occurrence of ischemia (p < 0.0001).

Conclusions. The baseline characteristics of SAH in the elderly were only slightly different from those in younger patients. In the elderly, the interdisciplinary approach may be considered useful to decrease the ischemic consequences.

Endovascular Coiling of Intracranial Aneurysms in Elderly Patients: Report of 205 Treated Aneurysms

Neurosurgery 66:714-721, 2010 DOI: 10.1227/01.NEU.0000367451.59090.D7

More elderly patients are presenting with intracranial aneurysms. Many are poor surgical candidates and often undergo endovascular treatment.

OBJECTIVE: We present our experience with embolization in elderly patients.

METHODS:We performed a retrospective review of a prospective database of elderly patients treated with coil embolization for intracranial aneurysms.

RESULTS: In a period of 16 years, 205 aneurysms were treated in 196 individuals (age range, 70–96 years; mean age, 77.3 years), including 159 females (average follow-up, 16.2 months). Ninety-seven patients presented with unruptured aneurysms, and 99 patients presented after subarachnoid hemorrhage; the diagnosis was confirmed by computed tomographic scan or lumbar puncture. Complete occlusion was achieved in 53 aneurysms (26%), with a neck remnant in 127 (62%), incomplete occlusion in 13 (6%), and 12 unsuccessful attempts. Postembolization, 89.3% of patients were neurologically intact or unchanged, whereas 8.7% had new deficits. Four patients died. By modified Rankin Scale score, at last clinical evaluation, 128 patients (65%) had a good outcome. Follow-up angiograms were available for 113 aneurysms; they revealed that 62% were unchanged, 21% were further thrombosed, and 17% had recanalized. Three aneurysms ruptured after treatment during follow-up. Rupture was not associated with incomplete occlusion or neck remnant results (P = .6). Twenty-five aneurysms required reembolization. Reembolization was not associated with new deficits or death (odds ratio, 0.56; 95% confidence interval, 0.19–1.58; P = .27).

CONCLUSION: Coil embolization of intracranial aneurysms is safe and effective in the elderly. Preembolization clinical condition strongly correlates with clinical outcome. Incomplete embolizations are not associated with a higher rerupture risk. Additional embolization does not affect the clinical results.

Meningiomas in the elderly, the surgical benefit and a new scoring system

Acta Neurochir (2010) 152:87–97 DOI 10.1007/s00701-009-0552-6

Objective The purpose of the study was to define and identify prognostic indicators within an elderly population of patients suffering from intracranial meningiomas. The clinical presentation of the patient with meningioma is diverse, manifesting as a different clinical entity in the elderly patient compared to a similar type of tumor in a young patient.

Methods Two hundred fifty patients aged over 65 years admitted to RAMBAM Medical Center with meningiomas from 1995–2005 were characterized. We report the present- ing symptoms, chronic illnesses, perioperative and long- term follow-up results for a 5-year period.

Results Based on univariate and multivariate analysis, significant prognostic indicators were identified and were implemented into a new geriatric scoring system (GSS) including tumor size and location, peritumoral edema, neurological deficits, Karnofsky score (Clancey J Neurosci Nurs 27:220, 1995; Crooks et al. J Gerontol 46:M139– M144, 1991), and associated diabetes, hypertension or lung disease. Seven outcome parameters were retrospectively tested using the scoring system, namely mortality, Barthel Index score (Mahoney and Barthel Md State Med J 14:61–65, 1965), Karnofsky score and consciousness expressed by the Glasgow Coma Scale score (Jennett and Bond Lancet 1:480–484, 1975) 5 years after surgery, as well as recurrence within and beyond 12 months. Age proved to inversely correlate with outcome. Morbidity and mortality were significantly lower in women. The extent of surgical resection (Simpson J Neurol Neurosurg Psychiatry 20:22–39, 1957) had no influence on function- al outcome, although radical resection was associated with significantly lower mortality. Generally, a GSS score higher than 14 was associated with a significantly more favorable outcome.

Conclusion The present results suggest that common experience-based considerations may be optimized and implemented into a simple scoring system that in turn may allow for outcome prediction and evidence-based decision making.
