Table 4

Tumor recurrence related to partial or complete surgical removal. No significant difference between recurrence percentages in group A and group B was noted. However, data were not statistically strong enough to draft definitive conclusions.

	Tumor recurrence (22 pts)
	Partial removal (7 pts)		Gross total resection (15 pts)
	Giant tumor	Nerve root strict adherence	Nerve root sacrificed	Nerve root preserved
Group A	4	0	3	6
Group B	1	2	0	6
