Table 5:

Incidence of nodal metastasis and lymphatic invasion according to a new radiological grouping

New category pN Ly P-valuea
GGO group (CTR ≤ 0.5) 0/126 (0%) 7/126 (5.5%) <0.0001
LCSC group 0/71 (0%) 12/71 (16.9%)
Part solid group (0.5 < CTR < 1) 9/106 (8.5%) 41/106 (38.7%)
Pure solid group (CTR = 1) 67/268 (25.0%) 187/268 (69.5%)

aFisher's exact test.

pN: pathological nodal metastasis; Ly: lymphatic invasion; GGO: ground glass opacity; CTR: consolidation tumour ratio; LCSC: lung cancer with scattered consolidation.
