Acute promyelocytic leukemia (APL) was diagnosed in 13 of 84 adult patients (15.4°/«) with acute myeloid leukemia (AML) first admitted between 1972 and 1976. All patients had clinical and/or laboratory evidence of defibrination syndrome. Four patients died of cerebral hemorrhage within 2 days of admission. Two patients died of generalized infection on days 7, and 16, respectively, after admission. The remaining 7 patients (54°/o) underwent complete remission (CR) with daunomycin, arabinosyl cytosine, and adriamycin. All patients received massive platelet transfusion, no heparin, and no granulocyte transfusion. CR was more frequent in patients with a very low blast cell count and a fibrinogen level higher than 100 mg/ 100 ml. Median survival of these seven CR patients with APL is similar (15 months) to that of CR patients with other types of AML treated at the same institution during the same period.
