Purpose: The aim of this study is to determine and to compare the oncological outcomes of bilateral reduction mammoplasty to standard breast-conserving surgery for breast cancer. Methods: One hundred sixty-two patients who received a quadrantectomy because of breast cancer (group 1) and 106 breast cancer patients with macromastia who underwent breast-conserving surgery via bilateral reduction mammoplasty (group 2) between 2003 and 2010 were enrolled in this study. Results: The mean follow-up time was 37 months for group 1 and 33 months for group 2. Surgical margins were wider than 2 mm in 82.7% and 10 mm in 76.5% of the patients in group 1. Eleven percent of patients had positive surgical margins in this group. When compared to group 2, the rates were 89%, 84%, and 8.4%, respectively. Three patients (1.8%) in group 1 and one patient (0.9%) in group 2 had local recurrence of the disease and received a mastectomy. No statistical significances were noted for either local recurrence or overall survival between the two groups. Conclusion: Bilateral reduction mammoplasty has some advantages as compared to the standard conventional breast-conserving surgery techniques without having any unfavorable effects on surgical margin confidence, local recurrence, and survival rates.

The Evaluatıon of Contralateral Breast Lesıons in Breast Cancer Patıents Usıng Reductıon Mammoplasty
Lutfi Dogan,Mehmet ali Gulcelik,Melda Bulut,Niyazi Karaman,Gamze Kiziltan,Cihangir Ozaslan 한국유방암학회 2011 Journal of breast cancer Vol.14 No.3
Purpose: This study evaluated the importance of routine pathological examination of contralateral breast specimens in breast cancer patients using reduction mammoplasty. Methods: The weight of breast tissue resected from the contralateral breast in 71 patients and the number of slices used for pathological evaluation were recorded. Breast lesions found in the contralateral breast and accompanying lesions with tumors were examined. Results: High risk proliferative lesions were reported in the contralateral breast of eight (11.2%) patients, and low-risk lesions were detected in 18 (25%). While the mean age of the patients with high-risk lesions was 45.6, it was 52.8 for the other patients (p=0.036). Conclusion: Bilateral reduction mammoplasty may be beneficial to delineate some pathologies in contralateral breasts even in those patients with normal clinical and radiological findings. The incidental discovery of these pathologies is much more likely in young breast cancer patients.

Drug induced liver injury (DILI) is a global issue and acetaminophen (APAP) is considered as the main cause of this. Due to increasing incidents of DILI, current study attempted to investigate an alternative but better role of terazosin (alpha-adrenergic blocker) in APAP-induced acute liver injury in an animal model using New Zealand rabbits. APAP (1 g/kg of body weight) was given to New Zealand rabbits either with or without terazosin (0.5 mg/kg) and serum was collected after 4 h. Serum alanine transaminase (ALT), alkaline phosphatase (ALP) and ferritin level were determined to analyze the liver functioning of treated rabbits. Furthermore, total cholesterol (TC), total lipids (TL), high-density lipoproteins (HDL), low-density lipoprotein (LDL) and triglycerides (TG) levels were estimated to find any change in lipid profile of the treated animals. Moreover, the urea and creatinine levels assayed the actual renal functionality. To identify any modification in gene expression, qPCR of cytochrome P2E1 (CYP2E1) was performed. Terazosin in combination with APAP enhanced liver functioning by reducing the levels of liver injury markers viz. ALP and ALT, while lipid profile was also lowered by down regulation of TC, TL, LDL and TG with enhanced HDL levels. It caused significant down regulation of expression level of CYP2E1. It is concluded that terazosin has better effects induced on the recovery of normal liver functioning, by improving the liver profile, lipid profile and renal functioning both at tissue and molecular levels.
