Strong expressions of VEGF-C, VEGFR1, VEGFR2, and VEGFR3 were most commonly found in tumors with mucinous histology, while the weakest expressions were observed in clear cell and endometrioid tumors (p = 0.033, p < 0.001, p = 0.027, p = 0.005, respectively). This evidence concerns the gene FLT1 and endometrioid tumor.
