摘要：Objective To assess the effectiveness and safety of axillary dissection in old women with breast cancer.Methods All randomized controlled trials on axillary dissection in old woman were retrieved in the Cochrane Library, PubMed, EMBASE and Chinese Biomedical Literature Database. Meta-analyses were completed using RevMan 5.1.Results Three eligible randomized controlled trials (RCTs) including 5337 patients were involved. There were weak evidences in favor of axillary dissection in old woman. The meta-analysis showed that the overall survival (OS) in 1, 3, 5 and 7 years and the disease-free survival (DFS) in 1, 3 and 5 years were not statistically different between axillary dissection patients and non-axillary dissection patients. However there was a statistical difference in 7-year DFS.Conclusions Axillary dissection does not show a survival benefit in the old women with breast cancer. Therefore it is not well-founded to do axillary dissection in old women with breast cancer.
摘要：@@ Breast cancer is one of the leading causes of cancer deaths among women[1].In the past 40 years,breast cancer incidence has doubled or even tripled in developed countries such as South Korea and Japan; whereas it is about 20% to 30% in China and India in the past decade[2-4].An increasing incidence rate of 3% each year was observed in mainland China[5].
摘要：@@ Breast cancer is a heterogenous disease with molecular alterations, cellularcomposition, and clinical outcome.The more we know about the tumor characteristics underlying the heterogeneity of the disease, the greater the opportunity to refine treatment options.Great emphasis has been placed uponhistopathological characteristics of breast carcinoma cells in order to define bettertreatment options for breast cancer patients[1-2].
