We report the first Japanese case of acute promyelocytic leukemia with t(11;17)(q23;q21) and CD56. A 41-year-old man with schizophrenia was hospitalized because of the appearance of blasts with Auer bodies in his peripheral blood. A bone marrow smear showed an abundance of abnormal cells with scanty azurophile granules in the cytoplasm and somewhat lobulated nuclei. Because the abnormal cells demonstrated strongly positive peroxidase reactivity with a few faggot bodies, the patient was given a diagnosis of acute promyelocytic leukemia (M3v according to the FAB classification). However, chromosome analysis revealed t(11;17)(23; q21). All-trans retinoic acid (ATRA) was not effective. Mitoxantrone was more effective than daunorubicin, and resulted in a complete remission with a normal karyotype. About 9 months later, the patient suffered a relapse. Surface marker analysis demonstrated blasts that were positive for CD56, CD13, and CD33. MEC (mitoxantrone, etoposide, cytarabine) therapy was ineffective. Although ATRA was administered at a dose of 80 mg/day for more than 2 months, the number of myelocytes and promyelocytes increased Finally CAG (cytarabine, aclarubicin, G-CSF) therapy was initiated, but the patient died due to intracranial invasion and hemorrhage accompanied by disseminated intravascular coagulation.

The aim of our study was to evaluate the impact of oral arsenic (the realgar-indigo naturalis formula, RIF) and all-trans retinoic acid (ATRA) on coagulopathy in acute promyelocytic leukemia (APL) compared with intravenous arsenic trioxide (ATO) and ATRA during induction. Mitoxantrone was added to all the patients at a dose of 1.4mg/m2 per day for 5-7 days. D-dimer levels, prothrombin time (PT), fibrinogen (Fbg) levels and the platelet count were comparably analyzed among 83 newly diagnosed APL patients treated with RIF (n=45) or with ATO (n=38). Since induction therapy with RIF and ATRA, the median levels of Fbg, PT and platelets were recovered to the normal range within 4days, 10days and 28days, respectively. The last day of platelet and plasma transfusion was day 12 (range: 0-24 days) and day 3 (range: 0-27 days), respectively. Among the 42 patients with a disseminated intravascular coagulation (DIC) score=4, the consumption of transfused platelets was less in the RIF group than that in the ATO group (P=0.037). In the 17 patients with a DIC score <4, prompt recovery of Fbg levels (P=0.028) was observed in the RIF group compared with that in the ATO group (P=0.401). RIF and ATO showed similar effects on the recovery of coagulopathy in APL patients. RIF had a potential beneficial effect in accelerating the recovery of thrombocytopenia and hypofibrinogenemia for subclinical DIC patients.
