The tumors with deep myometrial invasion (>1/2 myometrial depth) (19.4 vs. 10.1, p = 0.025), positive LVSI (18.0 vs. 10.9, p = 0.038), lymph node metastasis (20.9 vs. 11.5, p = 0.018), and advanced FIGO stages (stage III/IV) (20.9 vs. 11.5, p = 0.018) (all by one-way ANOVA) had significantly higher uPA expressions compared to those with superficial myometrial invasion (<1/2 myometrial invasion), negative LVSI, no lymph node metastasis, and early FIGO stages (stages I/II) (Table 2). This evidence concerns the gene PLAU and metastatic malignant neoplasm in the lymph nodes.
