treatments

Hi - my husband was diagnoised with spinal-cell sarcoma in 2006.  Removed a large 4 lb. tumor and then received chemo.  Had surgery again Dec. 2007 to remove smaller tumor in same area, left side.  The first surgery removed his adrenal gland and second removed his left kidney.  Just received his 3 month PET scan and small tumor growing again in same area.  Will need surgery again and probably chemo.  Does anyone have any other alternative treatments or sarcoma specialist.  We live in Washington.  Thank you
