Comparison of outcome to combined POG and FNCLCC grades

		Relative increase in risk of failure
Category	Estimated 5-year EFS	All patients (N=130)	Patients with localized disease (N=102)
FNCLCC grade 1 or 2 / POG grade 1 or 2 (n=42)	68%	1	1
FNCLCC grade 1 or 2 / POG grade 3 (n=44)	48%	1.7	1.7
FNCLCC grade 3 / POG grade 3 (n=44)	26%	2.5	4.0

	p=0.0018	P=0.01^*	P=0.0005^*

P-values refer to effect of grade after stratification by extent of disease (resected, size < 5 cm; resected, size ≥5 cm; unresected; metastatic disease)
