Myxofibrosarcoma High Grade 8 CM

Hi everyone. My 56 yr old husband has been diagnosed with a high grade, 8 cm, fast growing myxofibrosarcoma located at the bottom of his neck, on upper shoulder abutting the brachial plexus. We just completed visits with Vanderbilt team and are meeting with MD Anderson team 1-3 Dec. After much research, chemo does not seem to work on this type of dense tumor. Husband is strongly leaning towards starting radiation then surgery. Does anyone else have/had this type of tumor and location? I would love to hear from you. Thanks
