Surgery

Goal of surgery: clear margins of normal tissue around the entire tumour (“adequate margins”)

Enneking classification of surgical intervention

Intralesional resection

Tumor opened during surgery, or surgical field contaminated, or microscopic or macroscopic residual disease

Marginal resection

Tumor removed en bloc, however, resection throught the pseudocapsule of the tumor; microscopic residual disease likely Tumor and its pseudocapsule removed en bloc, surrounded by healthy tissue, within the tumor-bearing compartment The whole tumor-bearing compartment removed en bloc (e.g. above the knee amputation for a lower leg tumor)

Wide resection

Radical resection
