AUC of ROC analysis for folate receptor‐positive circulating tumor cells (FR⁺CTC), carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), and cancer antigen 153 (CA153), and that in their combination. FR⁺CTCs, AUC = 0.778, 95% CI = 0.6860 to 0.8707, p = 0.001; CEA, AUC = 0.614, 95% CI = 0.4974 to 0.7307, p = 0.073; CA125, AUC = 0.625, 95% CI = 0.5099 to 0.7396, p = 0.05; CA153, AUC = 0.725, 95% CI = 0.6141 to 0.8353, p = 0.004; The combined diagnosis model, AUC = 0.887, 95% CI = 0.8212 to 0.9518, p < 0.001
