Incidence of neck metastasis, recurrence, survival according to WPOI and tumor budding

Characteristic WPOI Tumor budding


WPOI 1, 2, 3 WPOI 4 WPOI 5 P-value w/o tumor budding w/ tumor budding P-value
Neck metastasis (n=18) 1 (5.6) 8 (44.4) 9 (50.0) 0.012* 6 (33.3) 12 (66.7) 0.100
Recurrence (n=17) 2 (11.8) 7 (41.2) 8 (47.1) 0.023* 5 (29.4) 12 (70.6) 0.009*
Survival (n=26) 10 (38.5) 9 (34.6) 7 (26.9) 0.016* 14 (53.8) 12 (46.2) 0.206

(WPOI: worst pattern of invasion, w/o: without, w/: with)

*P<0.05.

This P-value was calculated between non-aggressive WPOI (1, 2, 3) and aggressive WPOI (4, 5).

Neck metastasis includes patients with metastatic lymph node at first surgery.
