Fig. 6. Kaplan–Meier curve of loco-regional recurrence-free survival (LRFS) according to nearest margin 0.35 cm. In LRFS, the group with the margin nearest >0.35 cm in the recurrence-free survival curve showed higher recurrence-free survival, but it was not statistically significant (P=0.162), the group with non-aggressive worst pattern of invasion (WPOI) group showed higher recurrence-free survival in the curve (P=0.05), and the group with low-tumor budding had higher recurrence-free survival in the curve (P=0.024). Non-aggressive WPOI (WPOI types 1, 2, 3), aggressive WPOI (WPOI types 4, 5). Low tumor budding (less than 5 buds), high-tumor budding (≥5 buds). Buds defined as a single cancer cell or a cluster of less than 5 cancer cells in the stroma of the invasive front.
