Hello @barman I am a five year survivor of high grade dedifferentiated liposarcoma. Needless to say this is a hell of an ordeal. May we (collectively) ask where it is that you reside currently? My diagnosis followed a biopsy and then 4 weeks of radiation followed by surgery 3 weeks later. In my case it was determined that there wasn't a chemotherapy that would be helpful but that was 5 years ago and there are some great advances that have been achieved in the interim. I agree with the group that you would greatly benefit from a high level sarcoma center at this stage and Mayo Clinic is at the top along with a few others.
