Abstract:
Objective To discuss the values of three screening methods for the detection of early breast cancer,and to analyze the features of the screening cancer.Methods The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years.The three screening methods included physical examination with ultrasound and mammography,physical examination with mammography and mammography only.The rate of recall,biopsy,cancer detection of three methods were analyzed and the mammographic findings were reviewed Chi-square test or Fisher's exact test were used for the statistics.Results The recall rates were 4.90% (49/1001),6.90%(166/2407)and 4.48% (85/1899) in three methods respectively,the biopsy rates were 1.60% (16/1001),1.04% (25/2407) and 0.63%(12/1899),the cancer detection rates were 0.50% (5/1001),0.17% (4/2407) and 0 (0/1899).There were statistical differences among the three groups (X2=12.99,6.264,8.764,P < 0.05).Physical examination with ultrasound and mammnography had the highest cancer detection rate,ten breast cancers were detected and 8 were early stage breast cancer.Of seven cancers detected by mammography,only two were found by ultrasound.A cluster of calcifications were found in 2 cases,linear calcifications in 2 cases.One case presented as a asymmetric density,one as a asymmetric density with calcifications,one as multiple nodules with a duster of calcifications.Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review.Conclusion Physical examination with ultrasound and mammography is the best method for breast cancer screening.The breast cancer can be detected by mammography earlier than other methods.
