The treatment strategies of breast cancers depends on an array of factors like age at diagnosis, menstrual status, dietary pattern, immunological response, genetic variations of the cancer cells etc. Recent technological advancements in cancer diagnosis lead to the emergence of gene expression pattern for better understanding of the tumor behavior. It has not only bolstered the prognosis, but also the early diagnosis and therapy. The accuracy in disease prognosis can be boosted when gene expression signatures are combined with traditional clinicopathological features. This review explains how the evolution of gene expression signatures for breast cancers, its advantages and future prospects. In addition, an overview of currently available gene expression signature analysis tools and consolidated information on their current status and specific benefits, that can be availed for breast cancer diagnosis are also discussed.Surveys help health care professionals gather meaningful data that can guide decision making and improve practice.

Methods The existing BAUS guideline on the insertion of suprapubic catheters was reviewed and has been updated in light of both activity and outcome data published since the original guideline was written. A systematic review of all new data from 2010 onwards was carried out. This updated guideline is largely evidence-based but, where evidence was lacking, is based on the consensus of exper
