Abstract Abstract 4421 The coexistence of B-cell chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML) in the same patient is rare. A 61-year-old man developed a lymphocytosis with morphologic and immunophenotypic feature of B-CLL (stage I according to the modified Rai classification), without indications for treatment. Ten months later he presented with a markedly elevated leukocytes count and splenomegaly. Myeloblasts, promyelocytes, myelocytes and metamyelocytes appeared in his peripheral blood. A bone marrow aspirate was hypercellular with an increased proportion of the myeloid series in all maturative stages; the percentage of lymphocytes was 3%. The immunophenotypic study demonstrated the typical feature of chronic phase of CML, simultaneously 2% of CD5+ CD19+ cells have been found. Unstimulated bone marrow culture shoved a 46,XY,t(9;22)(q34;q11.2) karyotype, and interphase FISH detected the presence of BCR/ABL fusion with 4,55×106 of p 210 and 1,55×103of p 190 copies/ml. Previously it has been shown that these two different hematological malignancies derive from distinct progenitors. Disclosures: No relevant conflicts of interest to declare.

Abstract We describe the clinical, cytogenetic, hystopathologic, immunophenotypic and molecular findings of a rare case of Philadelphia positive chronic myeloid leukemia (Ph+ CML) and B-cell chronic lymphocytic leukemia (B-CLL) occurring simultaneously at diagnosis, in a 57-year-old female patient. In the present case, the patient showed at diagnosis leukocytosis (48.000/ul) with myelocytes and metamyelocytes along with well-differentiated neutrophils, but also with well differentiated lymphocytosis (28.992/ul) in peripheral blood (PB) and also in bone marrow (BM) aspirate cytology. FACS cytometry exhibited clearly two predominant separated cellular populations and the immunophenotype profile of the lymphoid component in BM and PB was CD5+, CD20+, CD23+, with light chain clonal restriction. The BM hystopathological analysis showed two distinct cellular populations, one lymphoid well differentiated CD5+/CD20+, and other myeloid, in several stages of differentiation. Cytogenetic analysis with unstimulated bone marrow culture confirmed the presence of Philadelphia chromosome but with additional translocation involving chromosomes 9, 10 and 22. Molecular studies showed the evidence of BCR-ABL positivity and the B-cell clone was documented by the presence of a clonal heavy chain immunoglobulin rearrangement. The patient was treated with imatinib mesylate 400mg/day, achieving complete cytogenetic response at the fourth month, and complete molecular response (nested PCR) of the BCR-ABL component at the sixth month of treatment. Besides, the absolute lymphocytosis was gradually reduced during the treatment exclusively with imatinib, achieving normal absolute values at the sixth month. This seldom described case of simultaneous occurrence of these two rare chronic hematological malignancies, brings interesting questions about the possible cellular origin and the correspondent mechanisms of clonal expansion. The therapeutic response of the B-cell lymphoid clone exhibited, brings also a possible relationship with the observation that the c-Abl could have enhanced expression in B-CLL cells, as described by Ke Lin et al, in which the c-Abl kinase activity could be inhibited by imatinib mesylate.

The coexistence of two diseases chronic myeloid leukemia (CML) and B-cell chronic lymphocytic leukemia (B-CLL) is a rare phenomenon. Both neoplastic disorders have several common epidemiological denominators (they occur more often in men over 50 years of age) but different origin and long term prognosis. In this paper we described the clinical and pathological findings in patient with CML in major molecular response who developed B-CLL with 11q22.3 rearrangement and Coombs positive hemolytic anemia during the imatinib treatment. Due to the presence of the symptoms of autoimmune hemolytic anemia and optimal CML response to the imatinib treatment, the decision about combined therapy with prednisone and imatinib was made. During the follow-up, the normalization of complete blood count and resolution of peripheral lymphadenopathy were noted. The hematologic response of B-CLL was diagnosed. The repeated FISH analysis of cultured peripheral blood lymphocytes showed 2% of cells carrying 11q22.3 rearrangement. At the same time, molecular monitoring confirmed the deep molecular response of CML. The effectiveness of such combination in the described case raises the question about the best therapeutic option in such situation, especially in patients with good imatinib tolerance and optimal response.

Purpose To determine the role of myeloablative conditioning and unrelated donor (URD) bone marrow transplantation in the treatment of patients with advanced B-cell chronic lymphocytic leukemia (CLL). Patients and Methods A total of 38 CLL patients received a matched URD transplant using bone marrow procured by the National Marrow Donor Program. The median age was 45 years (range, 26 to 57 years), the median time from diagnosis was 51 months, and the median number of prior chemotherapy regimens was three. Fifty-five percent of patients were chemotherapy refractory and 89% had received fludarabine. Conditioning included total-body irradiation in 92% of patients. Graft-versus-host disease (GVHD) prophylaxis consisted of methotrexate with cyclosporine or tacrolimus for 82% of patients. Results Twenty-one patients (58%) achieved complete response and six (17%) achieved partial response. Incidences of grades 2 to 4 acute GVHD were 45% at 100 days and incidences of chronic GVHD were 85% at 5 years. Eleven patients are alive and disease free at a median of 6 years (range, 3.0 to 9.0 years). Five-year overall survival, failure-free survival, disease progression rates, and treatment-related mortality (TRM) were 33%, 30%, 32%, and 38% respectively. Conclusion These data demonstrate that lasting remissions can be achieved after URD transplantation in patients with advanced CLL. High TRM suggest that myeloablative conditioning and HLA-mismatched donors should be avoided in future protocols, and it is mandatory to investigate transplant strategies with a lower morbidity and mortality, including the use of nonmyeloablative regimens.

Aim: The genetic mechanisms of resistance to chemotherapy in B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL) are not clear. We aimed to determine the peculiarities of abnormal karyotype formation in bone marrow (BM) cells and peripheral blood (PB) blast transformed B-cells in relapse of B-CLL/SLL. Materials and Methods: Cytogenetic GTG banding technique and molecular cytogenetic in interphase cells (i-FISH) studies of BM cells and PB blast transformed B-lymphocytes were performed in 14 patients (10 males and 4 females) with B-CLL/SLL. Results: The results of karyotyping BM and PB cells revealed the heterogeneity of cytogenetic abnormalities in combined single nosological group of B-CLL/SLL. In PB B-cells, chromosome abnormalities related to a poor prognosis group were registered 2.5 times more often than in BM cells. Additional near tetraploid clones that occurred in 57.1% cases were the peculiar feature of BM cell karyotypes. Chromosomal rearrangements characteristic of the group of adverse cytogenetic prognosis were revealed in all cases from which in 2 cases by karyotyping BM cells, in 6 cases in PB B-cells and in 8 cases by the i-FISH method in BM cells, i.e. their detection frequency was 3 times higher in PB B-cells and 4 times higher when analyzing by i-FISH in BM cells. Conclusions: Mismatch in abnormal karyotypes in BM and PB B-cells by the presence of quantitative and structural chromosomal rearrangements may be indicative of simultaneous and independent processes of abnormal clone formation in the lymph nodes and BM hematopoietic cells. Accumulation the information about previously unidentified chromosomal rearrangements in relapse of the disease may help to understand the ways of resistance formation to chemotherapy.

Abstract Abstract 4588 Background: Tyro 3 (Sky), Axl, and Mer receptors are members of the family of tyrosine kinases and Gas6 is their ligand molecule. In some types of cancer, upregulation of Axl/Gas6 indicated a worse prognosis, but an opposite situation was observed in renal “cell” carcinoma. This contradiction may suggest that Axl/Gas6 pathway varies depending on the type of cancer. The objective of this study is to investigate TAM receptors on surfaces of mononuclear cells in patients with B-Cell chronic lymphocytic leukemia (B-Cell-CLL). Material & Methods: B-Cell-CLL patients (grade 0–1, according to the classification of RAI), who were not on a drug treatment, were recruited in this study (n= 20; 9 female, 11 male). Their ages were 44 to 74 (mean: 63), and the control group consisted of 13 healthy volunteers (5 female, 8 male), whose age range is 20–89 (mean: 36). Mononuclear cells were isolated by density gradient centrifugation, and then surface TAM receptors were detected by flow cytometry. Mononuclear cell were stained with the primary antibodies against Tyro3, Axl and Mer. Results: The percentage of the surface TAM receptors on mononuclear cells from the patient group (25–75% interquartile range): Tyro 3= 25.50 (4.2– 45.62); Axl= 17/55 (5.57– 36.32), and Mer= 19.90 (1.92– 37.55). In the control group the following values were obtained: Tyro 3= 2.60 (1.35–3.25); Axl= 0.9 (0.4–2.6), and Mer= 2.50 (0.35–3.65). The percentage of three of them was significantly higher in the B-Cell-CLL group than those in the control group (P<0.01). Conclusion: In conclusion, this preliminary study showed that TAM receptors on surfaces of mononuclear cells are higher in patients with B-Cell-CLL patients than the control group. Gas6/TAM signaling may play a potential role in the pathogenesis of B Cell-CLL. Further studies are required to elucidate the actual role of Gas6/TAM signaling in B-Cell-CLL. Gas6/TAM signaling might be a new strategic goal for the treatment of B-Cell-CLL. Disclosures: No relevant conflicts of interest to declare.
