Extent of resection and the long-term durability of XXXX surgery.

@entity5 @entity1 @entity5513
OBJECT: With limited studies available, the correlation between the extent of resection and @entity5 recurrence in @entity5513 ( @entity5513 ) has not been definitively established. In this prospective study, the authors evaluated 772 @entity1 who underwent microsurgical resection of @entity5513 to analyze the association between total @entity5 resection and the @entity5 recurrence rate. METHODS: The authors selected all cases from a prospectively collected database of @entity1 who underwent microsurgical resection as their initial treatment for a histopathologically confirmed VS. Recurrence-free survival was analyzed using Kaplan-Meier analysis. The authors studied the impact of possible confounders such as @entity1 age and @entity5 size using stepwise Cox regression to calculate the proportional hazard ratio of recurrence while controlling for other cofounding variables. RESULTS: The authors analyzed data obtained in 571, 89, and 112 @entity1 in whom gross-total, near-total, and subtotal resections, respectively, were performed. A gross-total resection was achieved in 74% of the @entity1 , and the overall recurrence rate in these @entity1 8.8%. There was no significant relation between the extent of resection and the rate of @entity5 recurrence (p = 0.58). As expected, the extent of resection was highly correlated with @entity1 age, @entity5 size, and surgical approach (p < 0.0001). Using Cox regression, the authors found that the approach used did not significantly affect @entity5 control when the extent of resection was controlled for. CONCLUSIONS: While complete @entity5 removal is ideal, the results presented here suggest that there is no significant relationship between the extent of resection and @entity5 recurrence.
