	Two Year Failure Free Survival			Crude Patterns of Failure
	IGRT	Non-IGRT		IGRT	Non-IGRT

	(%)	(%)	P-value	N (%)	N (%)	P-value
Any Failure	43	45	0.12	35 (56)	67 (63)	0.24
Local	80	64	0.013	10 (16)	42 (39)	0.002

In patterns of failure, locoregional reflects simultaneous sites including local, regional, and/or distant.

^†

Distant disease was a component of failure in 33 of the 58 patients with locoregional failure. Abbreviations: N=Number, %=Percent
