The effect of weight in the outcomes of meningioma patients.

Abstract

BACKGROUND:

Meningiomas are more prevalent in women and mostly benign in nature. Our aim was to evaluate the association of weight and outcomes of meningioma patients undergoing craniotomy.

METHODS:

A retrospective analysis of meningioma patients discharged postcraniotomy between 1998 and 2007 was conducted. Univariate and multivariate analysis evaluated in-hospital mortality, complications, length of stay (LOS), and cost.

RESULTS:

According to the nationwide inpatient sample (NIS) database, an estimated 72,257 adult meningioma patients underwent a craniotomy in US hospitals during the study period. Female and male weight loss rates were 0.7% and 1.2%, respectively; obesity rates were 5.2% and 3.7%. Males had higher rates of malignant tumors than females (6.2% vs. 3.5%, P < 0.0001), and malignant tumors were more common in patients with weight loss (6.4% vs. 4.3%, P = 0.03). Weight loss was associated with higher mortality in men (OR 6.66, P < 0.0001) and women (OR 3.92, P = 0.04) as well as higher rates of postoperative complications in both men (OR 6.13, P < 0.0001) and women (OR 8.37, P < 0.0001). Furthermore, patients suffering weight loss had longer LOS and higher overall hospital cost when compared with all patients. In contrast, obesity seemed to reduce mortality (OR 0.47, P = 0.0006) and complications (OR 0.8, P = 0.0007) among women.

CONCLUSIONS:

In summary, weight loss seems to be the single most critical factor present in patients experiencing higher mortality, complications, hospital charges, and longer LOS. However, further studies aimed to assess the inter-relation of potential preexisting comorbidities and weight loss are needed to establish causation.
