I just wanted to point your interest to protocol combining DCA and arsenic trioxide. From what I read about how it works on molecular lever (I am not scientist so maybe someone can correct me) it should make DCA induce more apostosis than DCA alone. Specially if IV wersion of arsenic is used to lower toxic side effects of therapy. Arsenic is now used in oncology (in some lymphoma it shows more than 80% remission and complete cure). So since we have many smart people here someone can come out with protocol that will work for more patients. One thing is that IV arsenic costs a lot (350usd for 10mg) but maybe there are ways to develop something cheaper or try vit B17 ? After reading PubMed for few days I think arsenic is very promising in may types of cancer but usually works best combined with chemo or radio therapy - just like DCA.
