Adjuvant therapy for nonmetastatic osteogenic sarcoma: an evaluation of transfer factor versus combination...

A randomized study compared the effects of combination chemotherapy (high-dose methotrexate, adriamycin, and vincristine) with immunotherapy in the form of transfer factor in the adjuvant treatment of patients with nonmetastatic osteogenic sarcoma after apparent complete surgical ablation of the primary tumor. Thirty-two patients were evaluated. Of 22 patients who received chemotherapy, three died of drug-related complications and six were alive without disease recurrence between 260 and 673 days after operation. Ten patients in the transfer factor group converted their markers, and of these, five were alive without recurrence 420--753 days after operation. Neither treatment program was considered superior with respect to disease-free survival.
