Terminal Transferase

Twenty-eight patients with Philadelphia chromosome (Ph1)--positive and terminal transferase (TdT)--positive acute leukemia (AL) were treated with intensive chemotherapy used for adult acute lymphoblastic leukemia (L-10 and L-10M protocols). Fifteen patients had a documented chronic phase of Ph1-positive chronic myelogenous leukemia preceding the acute transformation (TdT + BLCML) while the remaining 13 patients did not (TdT + Ph1 + AL). An overall complete remission (CR) rate of 71% was obtained with a median survival of 13 months in the responders. Clinical presentation, laboratory data, cytogenetics, response to treatment, and survivals of the two groups of patients are compared. These results appear to be similar, suggesting a common or closely related origin. Since the overall survival of those receiving chemotherapy maintenance is poor, three patients underwent allogeneic bone marrow transplantation (BMT) from histocompatibility leukocyte antigen--matched siblings after they achieved CR. One of them is a long-term survivor (35 + months) with a Ph1-negative bone marrow. New techniques such as BMT should be considered in young patients with a histocompatibility leukocyte antigen--compatible sibling once a CR has been achieved.

Juvenile Form

The case of a patient with ecchymosis, hepatomegaly, leukocytosis, thrombocytopenia, and anemia at birth is presented. Throughout his course, thrombocytopenia, anemia, and leukocytosis without a marked increase in the number of blast forms in either peripheral blood or bone marrow persisted until the patient developed a blast crisis shortly before his death at age 4 months. This patient is the youngest reported to have the juvenile form of chronic myelogenous leukemia and the first that in the present era can be considered congenital in origin.

Abstract Context.—The immunophenotypic profile of basophils is not yet fully established, and the immunophenotypic changes in chronic myelogenous leukemia are not fully characterized. Objective.—To establish a comprehensive immunophenotypic spectrum of normal basophils and to assess the range of immunophenotypic aberrations of basophils in chronic myelogenous leukemia. Design.—Using 4-color flow cytometry, we compared the immunophenotypic profile of basophils in peripheral blood or bone marrow samples from 20 patients with no evidence of neoplasia to basophils from 15 patients with chronic myelogenous leukemia. Results.—Basophils in control cases were all positive for CD9, CD13, CD22, CD25 (dim), CD33, CD36, CD38 (bright), CD45 (dimmer than lymphocytes and brighter than myeloblasts), and CD123 (bright), and were negative for CD19, CD34, CD64, CD117, and HLA-DR. Basophils in all chronic myelogenous leukemia patients possessed 1 to 5 immunophenotypic aberrancies. The most common aberrancies were underexpression of CD38, followed by aberrant expression of CD64 and underexpression of CD123. CD34 and CD117 were present in cases with basophilic precursors. Myeloblasts showed a distinct immunophenotypic profile, as they typically expressed CD34 and CD117, showed dimmer expression (compared with basophils) of CD38, CD45, and CD123, and lacked expression of CD22. Conclusions.—Flow cytometric immunophenotyping can identify immunophenotypic aberrations of basophils in chronic myelogenous leukemia, and discriminate basophils from myeloblasts.

Abstract Cytogenetic studies were performed on nine patients with acute promyelocytic leukemia. Every patient had an identical translocation (15;17) or, in one case, a variant three-way rearrangement between chromosomes 7, 15, and 17. Another patient with chronic myelogenous leukemia was examined at the time of blastic crisis when the patient's bone marrow was infiltrated by hypergranular promyelocytes and blasts. Bone marrow cells contained a t(15;17) as well as a Ph1 chromosome. Only the latter abnormality was observed in the chronic phase of the disease. The translocation (15;17) was detected in all ten patients when bone marrow or peripheral blood cells were cultured for 24 hours prior to making chromosome preparations. However, the t(15;17) was not seen in three of these same cases when bone marrow cells were processed directly. These findings indicate that the t(15;17) is closely associated with acute proliferation of leukemic promyelocytes and that detection of this karyotypic defect may be influenced by the particular cytogenetic processing method used in different laboratories. An analysis of the banding pattern in the variant translocation provided additional evidence favoring chromosomal breakpoints at or very near the junction between bands 17q12 and 17q21 and at 15q22.
