A historical group consisting of 35 patients with osteosarcoma was compared to a concurrent group of 23 patients. The treatment for the primary tumors differed only slghtly in the two groups. A more active approach was adopted for treatment of pulmonary metastases in the concurrent group. The percentage of patients not developing metastases and the survival rate in the historical group were approximately one half those for the concurrent group. An analysis of prognostic factors disclosed differences between the two groups as regards the size and histological type of the tumor. The results of the study cast doubt on the suitability of historical controls in current clinical trials conducted to ascertain the effectiveness of adjuvant therapy for osteosarcoma.
