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 Impact of cytogenetic abnormalities on treatment with different purine nucleoside analogs in patients (pts) with B-cell chronic lymphocytic leukemia (B-CLL) is largely unknown. One of objectives of PALG-CLL3 trial, comparing cladribine plus cyclophosphamide (CC) with fludarabine plus cyclophosphamide (FC) in previously untreated progressive B-CLL, was to verify the response to treatment in subsets of pts characterized by common cytogenetic abberrations. Chromosomal abnormalities were assessed using fluorescence in situ hybridization (FISH) on interphase nuclei of lymphocytes on whole blood smears prior to the start of the study treatment. Pts were screened for trisomy 12, deletions (del) 11q, del 13q and del 17p using DNA probes: CEP12, LSI: ATM, D13S319 and p53 (Vysis), respectively. For the purpose of the present interim analysis complete cytogenetic results were available in 133 pts out of 423 pts included to the study. In this group the chromosomal aberrations were detected in 102 pts (77%) including single abnormalities observed in 69 pts (52%) and two or more aberrations in 33 pts (25%). Thirty-one pts (23%) exhibited a normal interphase FISH pattern. The most frequent single abnormality was del 13q found in 38 pts (29%), while del 17p, trisomy 12 and del 11q were identified in 14 pts (11%), 11 pts (8%), and 6 pts, (5%), respectively. The most frequently observed associations of chromosomal aberrations were: del 13q with del 11q (11 pts, 8%) and del 13q with del 17p (10 pts, 8%). Four pts (3%) revealed three chromosomal abnormalities including association of trisomy 12/del 11q/del 13q in two pts, trisomy 12/del 11q/del 17p in one pt and del 11q/del 13q/del 17p in one pt. Overall, treatment was completed and response assessed in 113 out of 133 pts with known FISH pattern. In this group of pts del 17p was the only chromosomal abnormality that correlated significantly with treatment outcome. Pts with del 17p (21, 19%) had lower probability to achieve a complete response (CR) (0.044). Interestingly, in independent analyses of both treatment arms, the negative impact of 17p was seen in pts treated with FC (p=0.002), but not in pts treated with CC (p=0.6). Moreover, comparing response rates between treatment arms we found that CC was superior to FC in terms of complete response in pts with del 17p (57% CR in CC v 14% CR in FC arm, p=0.04). In conclusion, chromosomal abnormalities can be detected in majority B-CLL pts requiring treatment. Our preliminary results suggest that CC combination may have some advantage in terms of CR achievement in B-CLL pts harboring del 17p.

Abstract This phase II study determined the efficacy and safety of alemtuzumab, a humanized anti-CD52 monoclonal antibody, delivered subcutaneously as first-line therapy, over a prolonged treatment period of 18 weeks in 41 patients with symptomatic B-cell chronic lymphocytic leukemia (B-CLL). Injections were administered subcutaneously 3 times per week, from week 2 to 3 onward. An overall response rate (OR) of 87% (95% CI, 76%-98%; complete remission [CR], 19%; partial remission [PR], 68%) was achieved in 38 evaluable patients (81% of intent-to-treat population). CLL cells were cleared from blood in 95% patients in a median time of 21 days. CR or nodular PR in the bone marrow was achieved in 66% of the patients and most patients achieved this after 18 weeks of treatment. An 87% OR (29% CR) was achieved in the lymph nodes. The median time to treatment failure has not yet been reached (18+ months; range, 8-44+ months). Transient injection site skin reactions were seen in 90% of patients. Rigor, rash, nausea, dyspnea, and hypotension were rare or absent. Transient grade IV neutropenia developed in 21% of the patients. Infections were rare, but 10% patients developed cytomegalovirus (CMV) reactivation. These patients rapidly responded to intravenous ganciclovir. One patient, allergic to cotrimoxazole prophylaxis, developedPneumocystis carinii pneumonia. Alemtuzumab is highly effective as first-line treatment in patients with B-CLL. Prolonged treatment is important for maximal bone marrow response. Subcutaneous administration induced very few “first-dose” flulike symptoms and may reduce health care costs in comparison with the intravenous infusions.
