CANCER SOLUTION: C-11 Methionine: Improved diagnosis of brain tumor

Dr. Carlos Trampal, chief medical care High-Tech Institute of Health Corporaci? CRC stated that the carbon 11 methionine gives better results than the analogues of glucose as a marker of brain tumors in positron emission tomography (PET).

Main contribution of methionine labeled with carbon-11 (MET), the expert said, is "clearly distinguishes a brain tumor a tumor or benign lesion not to offer a high contrast between diseased tissue and normal tissue. " He also stressed that allows a diagnosis of malignant transformation, something not possible with fl?ordeseoxiglucosa (FDG) in certain tumors cerebrales.As? same, to identify metabolic changes in tumor tissue after treatment. Thus, one can predict whether the patient will respond to treatment he has prescribed "and, on that basis, make the best therapeutic decision, " he said.

The expert cited other benefits, such as differentiating between recurrence and scar in patients who have had surgery, and provide guidance for diagnostic biopsies in cases where it is necessary, as it defines the contours of the tumor more accuracy of glucose-and know what the response to different therapies prescribed. For these reasons, Trampal felt that this substance "should be used routinely" for PET studies in brain tumors, since it would save unnecessary testing and diagnostic doubts.
