There is going to be a conference in Japan, end of October, about the prospects of the molecular targeted therapy for sarcoma. They will be discussing synovial sarcoma in particular.
For those interested about the research done in Japan, there is a pdf file that can be downloaded from internet for free at the following link:

It contains 2 articles about synovial sarcoma, one with the title “Synovial sarcoma is a stem cell malignancy” and another article with the title “Immunotherapeutic targeting of fusion genes in synovial sarcoma” which gives some information regarding phase I trials done in Japan that were using antigen-specific immunotherapy.
