Adenosarcoma

I was dignosed with Adenosarcoma in August and they gave me some chemo after a month they said that the tumor was back and they started me on radiation, after the radiation they did a biopsy and they said it wasn't all gone, now they are trying to decide if I can handle more radiation or get more chemo. Does this condition every go into remission? Does anyone know of other treatments? Tired of being sick!!!
