Study on the combined detection of mammography,ultrasound Doppler and serum tumor markers in the diagnosis of early breast cancer / 中国医学装备

ABSTRACT

Objective:To explore the values of single and combined detection of mammography,ultrasound Doppler and serum markers of tumor included serum prostate specific antigen(PSA),serum carbohydrate antigen 15-3(CA153),mucin 1(MUC1)and human growth differentiation factor 3(GDF3)in diagnosing early breast cancer.Methods:A total of 96 patients with breast cancer,who admitted to Tangshan People's Hospital from January 2018 to December 2021 and were confirmed by pathological examination,were selected as breast cancer group.At the same time,70 patients with benign breast diseases who received diagnosis and treatment in our hospital were selected as benign lesions group.In addition,50 normal people who were confirmed as health by physical examination in our hospital were selected as research subjects of healthy control group.The postoperative pathological examination was used as the gold standard to compare the diagnostic values of single mammography,ultrasonic Doppler examination,serum PSA,CA153,MUC1,GDF3 and the combined examination of them for breast cancer.Results:In the breast cancer group,78 cases of the 96 patients with breast cancer were diagnosed as malignant tumor by ultrasound on breast,with a positive detection rate of 81.3%,and 80 cases of them were diagnosed as malignant tumor by mammography X-ray examination,with a positive detection rate of 83.1%.The levels of serum PSA,CA153,MUC1 and GDF3 of breast cancer group were respectively higher than those of the benign lesion group and healthy control group,and the differences were statistically significant(t=8.783,10.361,11.258,18.965,9.564,12.658,12.688,20.163,P<0.05).Using breast cancer as the dependent variable,and using serum PSA,CA153,MUC1 and GDF3 as independent variable to perform Logistic regression analysis.The results of Logistic regression analysis indicated that serum PSA,CA153,MUC1 and GDF3 were important risk factors of breast cancer(OR value =1.165,1.168,1.472,1.248,P<0.05).The results of receiver operating characteristic(ROC)curve(95%CI),sensitivity and specificity of single application of each indicator of ultrasound on breast,mammography,serum PSA,CA153,MUC1 and GDF3 were respectively[0.723(0.595-0.851),82.56%and 67.32%],[0.761(0.636-0.886),85.79%and 65.36%],[0.833(0.726-0.941),81.48%and 85.73%],[0.837(0.738-0.926),61.25%and 70.17%],[0.768(0.648-0.889),71.49%and 80.87%],[0.613(0.469-0.758),52.94%and 50.57%].However,the AUC(95%CI),sensitivity and specificity of the combined application of 6 items were respectively 0.958(0.905-0.999),96.37%and 84.83%,which had higher diagnostic efficiency.Conclusion:The combined detection performance of mammography,ultrasound Doppler and serum PSA,CA153,MUC1 and GDF3 is higher than that of single each detection,which is helpful to conduct early identification and diagnosis for breast cancer.
