[Neoadjuvant chemotherapy in malignant fibrous histiocytoma of the limbs: 10 years of experience (1983-1992) at the Rizzoli Orthopedic Institute].
During the period September 1983 to December 1991, 47 patients with nonmetastatic malignant fibrous histiocytoma (MFH) of the limbs were treated using 3 different protocols of neoadjuvant chemotherapy activated at successive intervals. Surgery consisted of limb salvage in 41 cases and amputation in 6. After a mean follow-up of 6.5 years 33 patients (70%) had been continuously disease-free and 14 had undergone relapses. In the latter group the first sign of recurrence was metastasis in 12 cases and local recurrence in 2 cases. These results are distinctly better than those obtained in 20 patients treated during the same period using surgery alone (24% of disease-free survival and 30% local recurrence), and compared to those obtained in an earlier study in which surgery was associated with postoperative chemotherapy alone (59% of disease-free survival and 25% of local recidivation). The authors conclude that, as already observed in the case of osteosarcoma, neoadjuvant chemotherapy can significantly improve prognosis even in patients with bone MFH localised in the limbs. Moreover, given that, contrary to adjuvant chemotherapy, associated chemotherapy is effective not only in controlling the microscopic disease but also reducing the incidence of local recurrence, it enables amputation to be avoided in the majority of patients.
