MKI67 and gastric cancer: The VEGF level in GC was correlated to tumor maximum diameter (P < 0.05), invasive depth (P < 0.05), and lymph node metastasis (P < 0.05) that was linked to clinical phases, and the difference between groups was statistically significant (P < 0.05), which was positively correlated with Ki67-LI; the correlation coefficient was 0.254 and P = 0.026, which was not related to the positive expression of TIMP-1 in GC cells and stromal cells.
