We advocate surgery for POS and believe R0 (mR0 and mR1 resections) or planned R1 (mR1-dir) to preserve function are acceptable. We favor chemotherapy and surgery for PerOS, though a chemotherapeutic response is highly variable. High-grade tumors are the most infrequent subtype, but HGSO and dPOS seem to portend a poorer prognosis. Good function can be obtained.
