ABSTRACT

Objective To study the features of mammography,breast ultrasonography(US)and physical examination(PE)on 0-Ⅰstage(early stage)breast cancer,and to approach a diagnostic measure for early stage breast cancer(EBC).Methods Physical examination,ultrasonography and mammography were performed in 28 patients with pathologically proved breast cancer in 0-Ⅰ stage,and the data were analyzed.Results The accuracy of PE for 0-Ⅰstage of EBC was 57.1%(16/28),and the accuracy by US or mammography was 85.7%(24/28)and 89.3%(25/28),respectively.As the main clinical symptom of 0-Ⅰ stage EBC,breast lumps were found in 14 of 16 PE positive cases(87.5%).The main feature of EBC by mammography was the finding of a lump(14/25,56%).The low echo of a solid space occupying lesion was the main US feature of EBC(18/24,75%).The diagnostic accuracy of mammography for 0 stage EBC was 100.0%(8/8),while only 50%(4/8)by both US and PE.Malignant calcification was the main feature of o stage breast cancer in mammography.The diagnostic accuracy of US,mammography and PE for I stage EBC was 100.0%(20/20),and was 85.0%(17/20)and 40%(8/20),respectively.US was advantagious in detecting cancer in young patient with compact breast.Conclusion Early stage breast cancer often displayed atypical features in PE,US and mammography,which are important for the early-diagnosis of breast cancer,and false negative findings are inevitable in examination.Therefore,the diagnosis of early stage breast cancer should be made with.The findings of PE,US and mammography should be analyzed comprehensively,however,when one of examinations gives a positive finding,the diagnosis of breast cancer should be suspected,and further examination should be carried out to make an early diagnosis.
