Abstract:
Objective To observe the expression of serum carcinoembryonic antigen(CEA)and cytokeratin 19 fragment(CYFRA21-1)in peripheral blood of lung cancer patients,and to explore the prognostic value of combined imaging indicators for lung cancer patients.Methods Retrospectively analyze clinical data of lung cancer patients;all patients were followed up for six months after chemotherapy;observed the prognosis outcome of patients;included patients with cancer cell recurrence,metastasis or death in the poor prognosis group,and the rest of the patients in the good prognosis group.The baseline data,laboratory data and multi-slice spiral computed tomography(MSCT)results of the two groups before chemotherapy were compared;the application of peripheral blood biomarkers CEA and CYFRA21-1 combined with MSCT in predicting the prognosis of patients with lung cancer was analyzed.Results Among the 102 lung cancer patients who completed chemotherapy follow-up,16 had recurrence,10 had metastasis,and 5 died,accounting for 30.39％(31 cases/102 cases)of poor prognosis;the levels of CEA expression in the poor prognosis group and the good prognosis group were(28.03±8.49)and(17.03±5.78)ng·mL-1,respectively;the levels of CYFRA21-1 expression were(7.03±1.46)and(4.86±0.94)ng·mL-1,respectively;the levels of CA125 expression were(86.16±9.42)and(72.33±7.83)ng·mL-1,respectively;blood flow rates were(94.58±15.63)and(78.21±10.23)mL·s-1,respectively;surface permeability were(18.44±3.67)and(15.61±3.38)mL·min-1·100 g-1,respectively;time to peak were(26.58±5.50)and(20.15±3.49)s,respectively;tumor volume were(88.54±12.22)and(77.19±10.56)mm3,respectively;the differences between the two groups were statistically significant(all P＜0.05).The receiver operating characteristic(ROC)curve showed that the areas under the curves(AUC)of CEA and CYFRA21-1 plasma concentrations were 0.854 and 0.892;the AUC of blood flow rate,surface permeability,time to peak,and tumor volume were 0.810,0.719,0.834,and 0.744,respectively;and the AUC of the combined test was 0.954.Conclusion The levels of peripheral blood biomarkers CEA and CYFRA21-1 are highly expressed in the serum of lung cancer patients and the combination of CEA,CYFRA21-1 with imaging indicators is helpful in predicting the prognosis of lung cancer patients.
