N2 - Following preoperative chemotherapy of 9-18 weeks duration limb salvage procedures were performed instead of ablative surgery in about 1/2 of the patients (pts). Overall continuous disease-free survival rate is 69% (80/115) at 37 (21-51) months. 5 pts died from therapy related complications, 4 developed a local failure (2 following amputation and 2 following limb salvage each) and 26 pts developed pulmonary metastases. The incidence of pulmonary metastases after en bloc resection, but not after shank rotation plasty, was found to be significantly increased over that after ablative surgery (83% vs 60% metastases free survival (MFS) at 40 months, p less than 0.05). The outcome was most unfavourable following en bloc resection of large tumors (36% MFS) and of tumors poorly responding to preoperative chemotherapy. Delaying surgery for preoperative chemotherapy in itself did not influence MFS-rate but it enabled a thorough planing and preparation of surgical procedures. Chemotherapy has very much improved the prognosis of osteosarcoma, trials on limb salvage surgery are indicated therefore. However, these procedures appear to be hazardous by increasing the rate of pulmonary metastases. Until the underlying mechanisms are not uncovered and preventive strategies worked out, limb salvage surgery in osteosarcoma has to be regarded and handled as an experimental procedure.
