Prognostic impact of an integrative analysis of [18F]FDG PET parameters and infiltrating immune cell scores in lung adenocarcinoma

Table 4 Five-year survival rate according to the parameter groups

Stage	¹⁸F-FDG PET parameter	Immune cell score	Five-year survival (95% confidence interval)
Stage 0–2	TLR low	TFH low	0.686 (0.491–0.960)
	TLR low	TFH high	0.911 (0.8–1)
	TLR high	TFH low	0.492 (0.297–0.816)
	TLR high	TFH high	0.83 (0.635–1)
Stage 3–4	TLR low	TFH low	0.6 (0.293–1)
	TLR low	TFH high	0.5 (0.125–1)
	TLR high	TFH low	0.333 (0.108–1)
	TLR high	TFH high	0.25 (0.0458–1)

TLR low/TLR high: categorical groups divided by the median value of the tumor-to-liver SUVmax ratio, TFH low/TFH high: categorical groups divided by the median value of the follicular helper T cell score
