We studied the clinical, morphological, and immunologic characteristics of 11 patients with 11q translocation-associated acute leukemia. There were three patients with t(9;11)(p22;q23), one with a variant of the t(9;11), three with t(11;19)(q23;p13), two with t(1;11)(p32;q23), one with t(10;11)(p15;q22or23), and one with t(11;17) (q23;q25). The breakpoints in chromosome 11 clustered in band q23. The morphological feature was FAB-M5 in two patients, FAB-M2 in one, FAB-L1 in six, and lymphoblastic lymphoma in one. The remaining patient underwent morphological changes from FAB-L1 seen at the time of diagnosis to M5b at relapse. Immunologic marker studies in ten patients revealed that one had T cell type; another pre-B cell type; three CALLA- Ia- non-T, non-B type; two CAL-LA- Ia+ non-T, non-B type; two monocytic type (positive Fc-receptor); and the remaining one underwent phenotypic changes from CALLA+ Ia+ non-T, non-B type to monocytic type. The patients were usually young; five were under 1 year and two were 9 and 13 years. Hyperleukocytosis was observed in eight of the ten patients with acute leukemia, and two of the eight died of intracranial hemorrhage within two days of admission, associated with disseminated intravascular coagulation. These findings indicate that leukemia with the 11q23 translocation share certain characteristics in common, irrespective of the recipient chromosome, even though the latter may have some influence on the morphological and immunologic phenotype. Our data provide a hypothesis that multipotent stem cells are involved in the genesis of the 11q translocation-associated leukemia.

A 46-year-old white male presented with a two-week history of a flu-like illness and bleeding gums. A diagnosis of acute promyelocytic leukemia was made on bone marrow examination with accompanying DIC. All cytogenetically abnormal cells (28/30 at intake and 30/30 at two weeks post-induction) represented a single clone with apparent deletion of 1(p22) and 3(p25), and with a large, derivative chromosome 17. By conventional G- and C- banded analysis, the monocentric der(17) appeared to be disrupted distal to the typical (17q21) APL breakpoint, chromosome 15 did not demonstrate gross rearrangement, and the source of the additional material on the der(17) was unknown. Fluorescence in situ hybridization (FISH) with t(15;17), RAR alpha, and 17qter probes and with chromosome 1, 15, and 17 paints demonstrated that the der(17) consisted of a complex rearrangement with duplication of both RAR alpha and PML, insertion of chromosome 1 sequences, and double insertion of chromosome 15 sequences. The fusion of RAR alpha and PML consistent with APL appears to have occurred at the distal juxtaposition of these sequences in the derivative chromosome.

A 26-year-old woman was admitted to our hospital for lumbago on November 29, 1995. The white blood cell count was 6,500/microliter with 26.5% myeloblasts and the bone marrow was hyperplastic due to myeloblasts. Myeloblasts were negative for myeloperoxidase and positive for alpha-naphthyl butylate esterase, CD11a (89%), CD11b (38%), CD11c (92%), CD33 (91%) and HLA-DR (58%). Chromosomal abnormalities were recognized: 46, XX, t(9;11) (p22;q23), 45, XX, -7, t(9;11) (p22;q23) and 47, XX, +19, t(9;11) (p22;q23). Acute myeloblastic leukemia (M5a) was diagnosed. Disseminated intravascular coagulation was also present. The patient received induction therapy and achieved remission on January 9, 1996, but myeloblasts increased to 3.6% in bone marrow despite consolidation therapy. Low doses of cytarabine (AraC) and etoposide were instituted on March 7, granulocyte colony-stimulating factor (G-CSF) was started on March 15, and pronounced skin infiltration developed on March 18. The patient received reinduction therapy from April 16 and administration of G-CSF was combined for 2 days, and a marked increment of myeloblasts in the peripheral blood was observed. After discontinuation of G-CSF, myeloblasts decreased and skin infiltration disappeared. However, the patient died of cerebral infiltration on June 30. The response of myeloblasts to G-CSF by in vitro liquid culture was noteworthy. The present case stresses the requirement for great caution to be exercised in the use of G-CSF in patients receiving low dose AraC.
