I am trying to find out more information about teratomas with malignant transformation, specifically related to prognosis. I had a single mass removed with clean margins and no infiltration. Any studies that have been done about treatment options would be helpful. Also, are there any other published cases of teratoma and astrocytoma? I guess I am trying to find out if my type of teratoma would portend a better or worse prognosis than other types, especially given how fast mine developed.
