ABSTRACT
Objective To investigate the clinicopathologic characteristics and prognosis of triple negative breast cancer patients. Methods A retrospective analysis was performed for 1042 primary breast cancer patients admitted in the First Affiliated Hospital of Nanjing Medical University from January 2003 to December 2009.All breast cancer patients were categorized into three subgroups by immunohistochemistry:ERBB2 +,HR +/ERBB2 - and triple negative. Results Of 1042 breast cancer patients recruited,183 patients were in triple negative group.The rate of larger tumors ( greater than 2 cm in diameter) and grade Ⅲ in triple negative patients was higher than that in ERBB2 + and HR +/ERBB2 - patients (P ＜0.01 ).The positive rate of p53 status in ERBB2 + patients was higher than that in triple negative and HR +/ERBB2- patients (P ＜ 0.01 ).No significant differences were observed in other clinical variables.In survival analysis,more bone metastases were observed in HR +/ERBB2 - patients than in ERBB2 + and triple negative patients (P =0.006).However,no significant difference was observed in visceral metastases among the subgroups.There were significantly different recurrence-free survivals (RFS) among the three subgroups throughout the follow-up period ( P =0.029),the 5-year RFS of ERBB2 + was 80.3％,which was the worst in three groups. Conclusions Triple negative patients had higher rate of larger tumors (greater than 2 cm in diameter) and grade Ⅲ than that in ERBB2 + and HR +/ERBB2 - patients,while its 5-year RFS was higher than ERBB2 + patients.
ABSTRACT
ObjectiveTo study the scope of excison in breast-conserving surgery for breast carcinoma.MethodsClinical data of 275 breast cancer patients undergoing breast-conserving surgery in t he First Affiliated Hospital of Nanjing Medical University,the Affiliated Zhenjiang Hospital of Jiangsu University and Changzhou Traditional ChineseMedicine Hospital were retrospectively analyzed.The operation procedure and postoperative adjuvant therapy were carried out with the same protocol.Local and general conditions of patients were followed up regularly.Results271 out of 275 patients got follow-up.The follow-up rate was 98.5％.The follow-up time ranged from 1 month to 117 months,median follow-up time was 34 months.Six patients died of distant metastasis,2 with local recurrence.The 1-year,3-year,and 5-year overall survival rates were 99.5％,98.1％,and 95.7％,respectively.ConclusionsIt is safe to excise 1 cm normal breast tissue with clear margin confirmed by frozen section,followed by postoperative adjuvant therapy,endocrine therapy,and radiotherapy,this improves the life quality of patients with breast cancer.It is safe and effective to determine whether the disease is multicentric or multifocal by mammogram plus clinical breast examination.
ABSTRACT
Objective To discuss how to determine the operative margin in breast-conserving surgery in patient with early-stage breast cancer. Methods The breast-conserving surgery was performed on 111 patients with early-stage breast cancer who met the indication of breast-conserving. The operative incision was performed on normal breast tissue 1cm from the tumour edge and then the frozen sections of the surgical margin tissue were done to confirm that tumour was completely excised. The individualized therapy was performed according to pathologic examination and clinical stage. All patients were followed up regularly. Results 111 patients with early stage breast cancer received breast-conserving surgery and all had good curative effect except one patient had a local recurrence during the follow-up. Conclusions Operative incision on normal breast tissue 1cm from the tumour edge and frozen section of the surgical margin tissue are two crucial procedures to ensure the success of breast-conserving surgery and increase the life quality of patient with breast cancer.
