Table 3. Correlation of microvessel density (MVD) and Carcinoembryonic antigen-associated cell adhesion molecule 1 (CEACAM1) expression with local recurrence, metastasis, and cancer-related survival.

MVD and CEACAM1 expression	No.	local recurrence (P-value^c)	Metastasis (P-value^c)	Cancer-related survival (P-value^c)
Low MVD^a	45	0.089	0.112	0.001
High MVD^a	35	0.089	0.112	0.001
CEACAM1 low expression^b	45	0.563	0.21	0.048
CEACAM1 high expression^b	35	0.563	0.21	0.048

^a, MVD was categorized according to the median MVD of all tumors into low (< 30 microvessels/400× microscopic field of view) and high (≥30 microvessels/400× microscopic field of view); ^b, CEACAM1 expression was categorized into low (<66% of CEACAM1 positive tumor cells) and high (≥66% of CEACAM1 positive tumor cells); ^c, P-values of follow-up analyses were determined by log-rank test.
