Application of high frequency color Doppler ultrasonography combined with detections of serum FIB and CA199 in preoperative diagnosis of breast cancer / 中国医学装备

ABSTRACT

Objective: To investigate the application value of high frequency color Doppler flow imaging(CDFI)combined with serum fibrinogen(FIB)and sugar antigen 19-9(CA199)in the preoperative diagnosis of breast cancer.Methods: The clinical data of 226 patients with space occupying lesion of breast were analyzed retrospectively.According to the confirmed situation of postoperative pathological examination,they were divided into breast cancer group(158 cases)and breast disease group(68 cases).All patients received examination of preoperative CDFI and detections of preoperative serum FIB and CA199,and the values of single CDFI examination and it combined with detection of serum FIB and CA199 in preoperative diagnosis of breast cancer were compared.Results: In breast cancer group(158 patients),the ultrasonographic images of 146 patients showed the lumps were hypoechoic or weak echoes,irregular shape and uneven surface,and showed the change of lump appeared cauliflower shape,lobulated or crab foot shape.And the levels of serum FIB and CA199 of breast cancer group were significantly higher than those of breast disease group(t=6.821,t=20.061,P＜0.05),respectively.The sensitivity,negative predictive value and diagnostic coincidence rate of CDFI examination combined with detections of FIB and CA199 for diagnosis of breast cancer were 89.24％,79.76％and 92.04％,respectively.And these were significantly higher than those of single CDFI examination(x2=100.148,x2=37.666,x2=79.636,P＜0.05),respectively.Conclusion: The value of high frequency CDFI examination combined with serum FIB and CA199 in the preoperative diagnosis of breast cancer is significantly higher than that of single examination and single detection,and it has clinical application value.
