The object in this discussion is to analyze 100 cases of malignant bone tumor in which apparent cures have been effected, fourteen of which are from my private records. Eighty-six are from the Sarcoma Registry of the American College of Surgeons, of which eighty-five are accepted five-year cures; seventy-four are osteogenic sarcoma, ten are Ewing's sarcoma, and one is myeloma. One is a doubtful case of osteogenic sarcoma and is not accepted. Of 125 patients with primary malignant bone tumors from my private records there are thirty living and well at the present time, but only the fourteen cases in which sufficient time has elapsed to determine probable results and in which I am reasonably certain of the diagnosis will be considered.
Primary malignant tumors are classified for study as (1) osteogenic, those derived from any of the elements which are factors in the formation of bone, and (2) nonosteogenic,
