Use of Acellular Dermal Matrices in One-stage Implant-based Breast Reconstruction / 中国医学科学院学报

Implant-based breast reconstruction is the most common choice in breast cancer patients. Recently,the acellular dermal matrix (ADM) technique has been widely used in implant-based breast reconstruction in the western countries. This article briefly reviews the biological characteristics,history,types,surgical techniques,and postoperative complications of ADM.

Value of cardiac troponin I measurement in prediction of anthracycline-induced cardiotoxicity in breast cancer patients / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the value of cardiac troponin I (CTnI) measurement in predicting anthracycline-induced cardiotoxicity in patients with breast cancer.</p><p><b>METHODS</b>This study was conducted among 186 breast cancer patients receiving anthracycline-based chemotherapy. Serum cTnI concentrations before and after each cycle of the chemotherapy and the left ventricular ejection fraction (LVEF) before and at the 2nd, 4th and 6th months of the treatment were recorded. According to serum cTnI concentration, the patients were divided into CTnI+ group (with serum CTnI concentration of no less than 0.1 ng/ml, n=60) and CTnI- (<0.1 ng/ml) group (n=126).</p><p><b>RESULTS</b>No patients in this series experienced cardiac heart failure (CHF). The number of patients with a LVEF reduction by over 10% from the baseline was 16 (26.7%) in CTnI+ group, as compared to 7 (5.6%) in CTnI- group, showing a significant difference between the two groups (P<0.01).</p><p><b>CONCLUSION</b>CTnI can be a useful marker for early prediction of anthracycline-induced cardiotoxicity in patients with breast cancer.</p>
