(a) RFS curves for the patients of subgroups a, b and c classified by the combination of SUVmax1 and ΔSUVmax%. RFS curves were significantly different among these three groups (P = 0.0006). (b) RFS curves for the patients of subgroup A and subgroup “B + C”. RFS curves were significantly different between these two groups (P = 0.0002). Ten-year RFS rates were 78.8% in group A and 89.0% in group “B + C”
