Dear boobbuster: I am assuming by triple negative you mean ER/ PR/ and HER2 negative. Yes, there is research that is done on these types of cancers. In general terms, we know that hormone therapy and herceptin are not likely to work and therefore, the options have historically been limited to chemotherapy. Newer therapies targetting tumor blood supply or "antiangiogenesis" therapies are a potential option, in addition to chemotherapy, for triple negative breast cancers that have metastasized. Once the disease is metastatic, it is not usually considered curable. However, this does not mean that treatment will not help. Indeed, chemotherapy can sometimes reduce disease or keep it stable for a period of time. It is probable that you will be on some form of therapy for the rest of your life. Since responses to therapy and behavior of the disease can be quite variable, it is impossible to predict how long you are likely to live. You may benefit from looking into clinical trials at a large academic teaching hospital if you have not done this.
Take care,Liz.
