Doctors administer sclerotherapy by injecting a sclerant (a sterile chemical which irritates the vein lining) into your vein causing it to close and eventually be reabsorbed into the body. To compensate for the loss of the vein, blood circulation is re-routed through healthy veins.
Abstract. 1  Metaplastic breast cancer (MBC) is a rare subtype of invasive breast cancer that tends to have an aggressive clinical presentation as well as a variety of distinct histologic designations. Few systemic treatment options are available for MBC, as it has consistently shown a suboptimal response to standard chemotherapy regimens.
What is a meta-analysis? Meta-analysis is the statistical procedure for combining data from multiple studies. When the treatment effect (or effect size) is consistent from one study to the next, meta-analysis can be used to identify this common effect. When the effect varies from one study to the next, meta-analysis may be used to identify the reason for the variation. Why perform a meta-analysis? Decisions about the utility of an intervention or the validity of a hypothesis cannot be based on the results of a single study, because results typically vary from one study to the next.
