In-Hospital Complications After Surgery in Elderly Patients with Asymptomatic or Minor Symptom Meningioma: A Nationwide Registry Study

Atypical and anaplastic meningiomas in the later decades of life: A national cancer database analysis

PURPOSE

We conducted a National Cancer Database (NCDB) study to investigate the epidemiological characteristics and identify predictors of outcomes associated with geriatric meningiomas.

METHODS

The NCDB was queried for adults aged 60-89 years diagnosed between 2010 and 2017 with grade 2 and 3 meningiomas. The patients were classified into three age groups based on their age: 60-69 (hexagenarians), 70-79 (septuagenarians), and 80-89 (octogenarians). The log-rank test was utilized to compare the differences in overall survival (OS). Univariate and multivariate Cox proportional hazards regressions were used to evaluate the mortality risk associated with various patient and disease parameters.

RESULTS

A total of 6585 patients were identified. Hexagenerians were the most common age group (49.8%), with the majority of meningiomas being classified as grade 2 (89.5%). The incidence of high-grade meningiomas increased in all age groups during the study period. Advanced age, male sex, black race, lower socioeconomic status, Charlson-Deyo score ≥ 2, and higher tumor grade were independent factors of poor survival. Among the modes of treatment, the extent of surgical resection, adjuvant radiotherapy, and treatment at a noncommunity cancer program were linked with better outcomes.

CONCLUSION

In geriatric patients with high-grade meningiomas, the greater extent of surgical resection and radiotherapy are associated with improved survival. However, the management and outcome of geriatric patients with higher-grade meningiomas are also associated with several socioeconomic factors.

The 5-Factor Modified Frailty Index as a More Useful Associated Factor Than Chronological Age After Unruptured Cerebral Aneurysm Surgery: A Nationwide Registry Study

BACKGROUND

Although chronological age is associated with mortality and morbidity after surgery for unruptured cerebral aneurysms (UCAs), there is little evidence regarding an association between the simplified 5-factor modified frailty index (mFI-5) and postoperative outcomes based on age group.

OBJECTIVE

To investigate the association of the mFI-5 score with worse outcomes, mortality, and complications in patients after surgery for UCA by chronological age groups using a Japanese national database.

METHODS

This study included 32 902 patients with UCAs enrolled in a Japanese national database between 2011 and 2015. Age group (younger than 65 years, 65-74 years, and 75 years or older), sex, UCA location, treatment, medications, Barthel Index (BI), medical history, mFI-5 score, and in-hospital mortality and complications were evaluated. We identified risk factors for worsening BI score, in-hospital mortality, and overall postoperative complications in each age group.

RESULTS

In total, 14 465 patients were enrolled in this study. Multivariable analysis showed that elderly groups and patients with an mFI-5 score ≥2 items were associated with worsening BI scores (odds ratio 1.95; 95% CI 1.52-2.51) and in-hospital complications (odds ratio 1.79; CI 1.49-2.15), despite having no association with in-hospital mortality. Multivariable analysis by age groups showed that the mFI-5 score ≥2 items was associated with in-hospital complications in all age groups, unlike chronological age in patients younger than 74 years.

CONCLUSION

The mFI-5 score was a more useful associated factor of in-hospital complications than chronological age in patients younger than 74 years undergoing surgery for UCA.

Perioperative Surgical Risks in Patients With Hemangioblastomas: A Retrospective Nationwide Review in Japan

BACKGROUND

The perioperative risk of sporadic hemangioblastomas (HBs) and von Hippel-Lindau disease (VHL)-associated hemangioblastomas (VHL-associated HBs) remains unclear due to the rare prevalence of HB. Therefore, this study aimed to clarify risk factors for better surgical management of patients with HBs.

METHODS

A retrospective analysis of surgically treated HB patients registered in the Diagnosis Procedure Combination database of Japan, between 2010 and 2015, was performed. Age, sex, sporadic HBs or VHL-associated HBs, medical history, tumor location, hospital case load, postoperative complications, and Barthel index (BI) deterioration were assessed. We also evaluated the outcomes and factors of perioperative BI deterioration.

RESULTS

In total, 676 patients with 609 intracranial lesions, 64 spinal lesions, and 3 with both types were eligible. Among them, 618 and 58 patients had sporadic HBs and VHL-associated HBs, respectively. The rates of perioperative BI deterioration were 12.5% and 12.2% for sporadic HBs and VHL-associated HBs, respectively. Perioperative mortality was 1.8% and 0% for sporadic HBs and VHL-associated HBs, respectively. Male sex, old age, high hospital case load, and medical history of diabetes mellitus were significantly associated with perioperative BI deterioration in all cases and sporadic HBs. Only medical history of diabetes mellitus was a significant risk factor for perioperative BI deterioration in VHL-associated HBs.

CONCLUSIONS

No differences in perioperative BI deterioration rates between sporadic HBs and VHL-associated HBs were found. However, different risk factors for perioperative BI deterioration were identified. Consideration of these risk factors is recommended in all patients undergoing surgery for HB.
