ABSTRACT
Objective To compare the effect between Mammotome minimally invasive surgery and traditional surgery in resection of youth giant breast fibroadenoma (YGBF).Methods We randomly selected 73 patients who had YGBF and already accepted surgical treatment in our hospital from Jul.2009 to Jan.2016.The 75 patients recruited from screening programmes were alloted to either treatment according to their choice (37 cases in MS and 38 cases in traditional surgery).The median follow-up was 18 months (from 6 to 36 months).Comparative analysis was done between the two groups in operation time,incision healing time,incision length,intraoperative bleeding,wound infection,subcutaneous hematoma,residual tumor,breast deformation,scar size,and patient satisfaction degree.Results There was no statisticaly significant difference betwen these two groups in operation time,intraoperative blood loss,incision infection,subcutaneous hematoma,or residual tumor (P＞0.05),however,MS group was superior to traditional surgery group in the incision healing time,incision length,breast deformation,scar size and postoperative satisfaction degree,and the difference was statistically significant(P＜ 0.05).Conclusion The advantage of Mammotome minimally invasive operation auxiliary for YGBF is obvious,such as fast wound healing,small incision,infection rate,small breast without deformation and scar etc.,also higher satisfaction degree to the treatment,which is regarded as the preferred surgical treatment for YGBF patients.
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 .
