Abstract:
Objective:To explore the identification value of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment (Cyfra211), thyroglobulin (TG), ferritin (Fer) and procalcitonin (PCT) in fine needle aspiration eluent in benign and malignant cervical nodules, and acquire the optimal diagnostic model.Methods:Three hundred and ninety-six single cervical nodule patients who underwent fine needle aspiration biopsy from August 2017 to August 2019 in the Center Hospital of Xiaogan City of Hubei Province were selected. The fine needle aspiration eluent levels of CEA, SCC-Ag, Cyfra211, TG, Fer and PCT were detected by electrogenerated chemiluminescence method. The results of cytopathological diagnosis were regard as "gold standard", and the diagnostic efficiency of single and combined indexes in fine needle aspiration eluent were analyzed by receiver operating characteristic (ROC) curve.Results:Among the 396 patients, malignant nodules was in 101 cases, and benign nodules was in 295 cases. The fine needle aspiration eluent levels of CEA, SCC-Ag, Cyfra211, TG and Fer in patients with malignant nodules were significantly higher than those in patients with benign nodules: (27.73 ± 10.63) μg/L vs. (16.81 ± 8.18) μg/L, (1.59 ± 0.74) μg/L vs. (1.09 ± 0.83) μg/L, (3.31 ± 1.48) μg/L vs. (1.66 ± 0.59) μg/L, (144.96 ± 38.93) μg/L vs. (95.03 ± 47.23) μg/L and (191.18 ± 80.13) μg/L vs. (137.87 ± 63.22) μg/L, the PCT was significantly lower than that in patients with benign nodules: (0.61 ± 0.24) μg/L vs. (1.01 ± 0.52) μg/L, and there were statistical differences ( P<0.01). The ROC curve analysis result showed that the CEA, Cyfra211 and TG had super diagnostic value (area under curve>0.7, Youden index>0.5); the area under curve of CEA, Cyfra211 combined with TG was significantly higher than other combined detection of 2 indexes ( P<0.05). Conclusions:The combined detection of CEA, Cyfra211 and TG in fine needle aspiration eluent can effectively distinguish the benign and malignant cervical nodules.
