Serum levels of VEGF and VEGF-C in patients with endometrial cancer.

Abstract

Endometrial cancer (EC) is the most common type of uterine cancer. A dualistic model of endometrial tumorigenesis serves as a useful way of categorizing these cancers in terms of both etiology and clinical behavior. There are two types of EC: type I and type II. Type I is so-called estrogen-dependent, and appears mostly in pre- and perimenopausal women, it is well differentiated and therefore has a better prognosis. Type II EC is estrogen-independent, diagnosed mostly in postmenopausal women, thin and fertile women, or in women with normal menstrual cycles. It is aggressive and has a worse prognosis than type I. The aim of this study was to evaluate the relationship between the pretreatment serum levels of VEGF and VEGF-C and the outcome of EC patients. A total of 98 patients treated between 1999 and 2003 were included in this study. Circulating VEGF and VEGF-C levels were determined using ELISA kits. VEGF levels among the 76 patients with type I, and the 22 patients with type II EC were significantly higher than those found in the healthy control subjects (p < 0.001). The differences in mean values of VEGF-C were highly significant in both types of tumor examined compared to the control (p < 0.001). The results demonstrate that serum VEGF concentration correlated significantly with advanced FIGO stage in type II EC (p < 0.001). The preoperative VEGF-C level correlated with advancing tumor stages in type I EC (p < 0.05). An elevated preoperative VEGF-C was an independent risk factor for disease-specific survival in patients with type II tumors. Thus, in type II EC patients with high preoperative levels of VEGF-C, pelvic and para-aortic lymphadenectomy should be performed. However, the value of longitudinal measurements of the markers used is yet to be determined.
