(A) Representative flow cytometric analysis from a patient with ovarian cancer. Left: flow cytometry gating. Middle: isotype negative control for flow-cytometry. Right: representative flow cytometric analysis for determining the number of CD34/VEGFR2 double-positive cells with a value of 1.61%. (B) Comparison of circulating EPC levels in ovarian cancer patients and healthy subjects. Data are expressed as mean ± SE (**P < 0.01, *P < 0.05). (C) Kaplan-Meier overall survival curve of patients with ovarian cancer according to pre-treatment circulating EPCs numbers (P = 0.012). The cutoff value between low and high pre-treatment EPC levels was set at 945 EPCs/ml of peripheral blood (median value).
