Journal of International Oncology 2015;42(11):805-808
Objective To investigate the clinical pathologic characteristics and prognosis of bilateral breast cancer, and to determine whether clinical factors is related to p53 gene mutation.Methods Archival material was reviewed from 48 cases of bilateral breast cancar.The clinical and pathological features of bilateral breast cancer were compared and summarized.Immunohistochemical stains for P53 were performed on 33 cases of bilateral breast cancer, 141 cases of unilateral breast cancer were also examined as control.Results The five-year survival rate for bilateral breast cancer patients was 70.5%.The median age when bilatereral breast cancer first dignosed was 47.5 (range from 27 to 69).The median time interval between the first and the subsequent breast cancer diagnosis was 9.5 months.Invasive ductal breast carcinoma was the main pathologic type of bilateral breast cancer.88.5% of bilateral breast cancer would have the same estrogen receptor (ER) status and 81.8% would have the same human epidermal growth hormone receptor 2 (HER2) status between the first and secondary primary tumors.Mutation p53 was more common among the bilateral breast cancer patients compared with the unilateral breast cancer patients (45.5% vs.26.2%, x2 =4.711 ,P =0.030).There was no difference on the overall survival between bilateral breast cancer with p53 (+) and p53 (-)(x2 =0.434,P =0.510).Conclusion The main pathologic type of bilateral breast cancer is invasive ductal breast carcinoma, there is a good match of the ER and HER2 status between the first breast cancer and the contralateral one.Bilateral breast cancer patients have a similar overall survial with the unilateral breast cancer.p53 mutation is more common among bilateral breast cancer patients than those with unilateral breast cancer.
2.Research progress on bilateral breast cancer
Journal of International Oncology 2013;(3):208-211
Women diagnosed with breast cancer have a significantly higher risk of developing contralateral breast carcinoma.When the dignosis ofbilateral breast cancer (BBC)is established,the challenges for the doctors are to determine contralateral breast carcinoma is metastasis or primary lesions.The pathological type,receptor status,biological behavior and the prognosis of bilateral breast cancer are the issues have to be considered.On the other hand,we discuss which type of breast cancer trend to be bilateral breast cancer,thus more effective follow-up and preventive procedures would be applied on this part of patients to improve their quality of life and the curative rate.

Objective: To explore influence of long-term oral valsartan-angiotensin II type 1 receptor blocker on ventricular arrhythmia after myocardial infarction (MI) in rabbits and its possible mechanism. Methods: A total of 24 New Zealand rabbits were randomly divided into sham operation group (n=8), MI group (n=8) and valsartan group (n=8) according to number table. Sham operation group only received thoracotomy without ligation of anterior descending branch of left coronary artery (LAD), while MI group and valsartan group received ligation of anterior descending branch of LAD. Valsartan group received valsartan gavage (10 mg•kg-1•d-1) since the second day after operation, three groups all were fed for 12 weeks. Mono active potential (MAP) of left ventricular myocardial cells of subendocardial myocardium(inner layer myocardium), subepicardial myocardium(outer layer myocardium)and middle layer myocardium were recorded before MI and 12 weeks after MI, and times of provocative malignant arrhythmias were recorded on 12 weeks after MI in three groups. Results: 1. Ventricular tachycardia or fibrillation (VT/ VF) episodes were markedly decreased in VAL group than that in MI group on 12 weeks after MI [(3.1±0.8) vs. (12.7±1.5), P<0.05]; 2. After MI 12 w, the action potential duration to 90% repolarization (APD90) of three-layer ventricular myocytes in MI group was prolonged than that before MI [(259.2±22.1)ms,(288.0±25.8)ms,(244.6±22.6)ms vs.(230.1±23.2)ms,(244.2±23.4)ms,(229.0±21.7)ms, P<0.05 or<0.01];but there were no significant difference in APD90 of three layers ventricular myocytes between before and after MI in valsartan group (P>0.05 all); Compared with sham operation group and valsartan group, there was significant prolonged in transmural dispersion of repolarization (TDR) [(18.8±6.2) vs. (23.9±7.7) vs. (37.2±10.2), P<0.05 or<0.01] in MI group; There was no significant difference in TDR between valsartan group and sham operation group (P>0.05). Conclusions: Long-term oral valsartan can significantly reduce malignant ventricular arrhythmia incidence in rabbits after MI, which may be related to improving TDR in rabbits after MI.
