The clinical value of combined diagnosis in the diagnosis of early breast cancer

Abstract

Objective To investigate the clinical value of serum tumor makers CA15-3,19 fragments of cellular keratin antigen(CYFRA21-1)combined with the color Doppler ultrasound and mammography X-ray in diagnosis of early breast cancer.Methods According to the postoperative pathologic diagnosis,collected 106 cases of patients with breast cancer (breast cancer group) and 50 cases of patients with benign breast lesions (control group),the serum tumor makers CA15-3,CYFRA21-1,the color Doppler ultrasound and mammography X-ray were compared with postoperative pathology and statistical analyzed retrospectively.Results The sensitivity of CA15-3 was 63.2%(67/106),specificity was 94.O% (47/50);the sensitivity of CYFRA21-1 was 73.6%(78/106),specificity was 88.0%(44/50);the sensitivity of color Doppler ultrasound was 77.4%(82/106),specificity was 90.0%(45/50);the sensitivity of mammography X-ray was 75.5%(80/106),specificity was 92.0%(46/50);the sensitivity of the four combined detections was 96.2%(102/106),specificity was 80.0%(40/50).The sensitivity of combined detection was higher than any of them individually,there was statistical significance (P<0.05).Conclusions Combined diagnosis is an effective way of early breast cancer detection.It has high positive rate of diagnosis and reliable guidance significance for diagnosis and treatment.
