Notes: The Enneking staging system was officially published by Enneking in 1980 based on the setting of surgical grade (G), local range of tumor (T), and the existence or nonexistence of local or distant metastasis (M). IIa indicates the high malignancy, inner compartment, and no metastasis, while IIb represents the high malignancy, outer compartment, and no metastasis.
