title: [Procedures and results of limb salvage surgery of musculoskeletal sarcoma].
abstract: During the 8-year period beginning 1979, 116 cases of musculoskeletal sarcoma were treated by limb salvage operation. Of these, the local recurrence rate was 9% and the postoperative metastatic rate was 28%. The limb salvage rate was about 80%. Limb salvage procedures were generally performed using curative surgical procedures without preoperative adjunctive therapy. However, reduction of the surgical margin to achieve local cure was made possible by combined therapy with preoperative adjunctive chemotherapy or radiotherapy. The wide procedures combined with preoperative adjunctive therapy achieved a local curability rate equal to curative procedures. Marginal procedures following preoperative radiotherapy were also undertaken in those cases in which the tumor was located in an area for which curative or wide procedures were not feasible. Also, similar procedures were performed for patients of advanced age, patients with lung metastasis, patients who refused ablative surgery, and for extirpation of lymph node metastases. Accordingly, we were able to determine which procedures best ensure local curability. Also, the most significant prognostic factor was found to be local recurrence caused by inadequate surgical margin. This was especially true in the treatment of high malignant sarcoma. Moreover, from analysis of recurrent cases, the suggested factors contributing to local recurrence were: the invasive character of the tumor, lymph node metastasis, skip metastasis, tumor dissemination due to pathological fracture, previously performed inadequate surgery, venous invasion, and multicentrical occurrence of certain tumors.
