We think the most effective treatment option for me at this stage is Votrient/ Pazopanib. Votrient has only been recently FDA approved in the USA and is a smart new drug which targets the Sarcoma Cancer cells; it's not a curative treatment but interferes with the growth and reproduction of the cancer cells and slows their spread in the body.
Reviewing a dozen individual cases on our synovial sarcoma online forum it is well regarded and the drug is very well tolerated with few side effects; for some it has had very positive impacts, for most it has brought quality time for a few months, for a few it has no impact. The advertised efficacy is that it has extended life by 3 months compared to no treatment. Such where things are at, I am very happy to take those odds. More about Votrient here.
