Abstract:
Objective To analyze the clinicopathological features and prognosis of patients with occult breast cancer ( OBC) , as well as to explore the best treatment .Methods The clinical data of 72 patients with OBC confirmed by pathology were retrospectively analyzed , while 320 cases with other kind of breast cancer were the control group .Results Axillary mass was the first sign of the 72 patients with OBC.The diagnosis rate of MRI was higher than mammary graphy ( 71.4% vs 53.5%) .The difference had statistical significance (χ2 =11.876, P=0.001) .The characteristics of OBC with axillary lymph node metastasis was mainly moderately or low differenti -ated, usually with diffuse infiltrative cancer cells , flaky, like large Apocrine cells.Compared with the control group, the positive rate of CK7, CK20 and TTF-1 had no statistical differences (χ2 =0.058, P=0.810).The posi-tive rate of ER and PR was 46.7% and 36.7%, lower than the control group (χ2 =4.535, P=0.033).Clinical stage, operating method and the number of lymph node metastasis may be the independent factors influencing prog -nosis.Conclusions Axillary mass is the first symptom of OBC .To combine MRI with immunohistochemistry is helpful in diagnosis and differential diagnosis of the disease .The positive rate of ER and PR for OBC patients is low.Modified radical mastectomy combined with adjuvant therapy may be the better choice .
