Hi @cootiekim - my son has synovial sarcoma (started in kidney) and in lungs within a month (very aggressive). He’s done 6 cycles of AIM (doxy/ifos) which was brutal. There is a new immunotherapy out called Tecelra- only available at select cancer centers. He’s had it but too soon to know how it’s worked. Hey amazing docs. Not to put down Mayo, but MSK is amazing and are on cutting edge of synovial sarcoma research. Look up Dr. Sandra D’Angelo and her team.
