Table 6 Response, recurrence, OS, RFS in patients with AFP levels < 100 after classification into the low- and high-risk groups by the AFP model

		Low-risk	High-risk	P value	Sig.
		n = 57	n = 22	P value	Sig.
Response	Complete response	52 (91.2%)	16 (69.6%)	< 0.05	S
	Partial response	5 (8.8%)	4 (17.4%)
	Stationary disease	0 (0.0%)	2 (8.7%)
	Progressive disease	0 (0.0%)	0 (0.0%)
RFS (months)	Median	13	6	> 0.05	NS
RFS (months)	Range	3–36	3–30	> 0.05	NS
Recurrence	No recurrence	15 (28.8%)	3 (18.8%)	> 0.05	NS
Recurrence	Recurrence	37 (71.2%)	13 (81.2%)	> 0.05	NS
OS (months)	Median	18	16	< 0.01	HS
OS (months)	Range	10–42	3–30	< 0.01	HS

RFS Recurrence-free survival, OS, Overall survival, NS Nonsignificant, S Significant, HS Highly significant
