The ability to achieve results comparable to those of previous clinical studies in our CML cohort was influenced by centralised care. Decisions not to initiate imatinib or to delay AHSCT may have a negative impact on OS, but comorbidities may limit the treatment potential of imatinib in the elderly.

Objective: The hospitalization of the patient during the critical myelosuppressive period after chemotherapy is often complicated by infections caused by nosocomial pathogens, what is associated with a high antibiotics consumption and with prolongation of the period of hospitalization. These fi ndings have led many centres to change their policy from "in-hospital" to "out-hospital care". In this retrospective study we tried, on the basis of our experiences, to identify the feasibility and safety of this approach. Patients and methods: We studied 56 patients with the acute myeloid leukemia treated in our clinic with the consolidation chemotherapy. We compared two groups of patients. In the fi rst group, the patients were discharged upon completion of chemotherapy, consequently followed up as outpatients. Patients in the second group were observed in hospital during the entire nadir. Following 41 courses, patients were discharged and instructed to return immediately if fever or any other change of their clinical status occurred. Results: In 24 cases after chemotherapy, the patients returned to the hospital after a discharge (in 23 cases because of fever), in 17 cases of nadir periods the hospitalisation was not necessary at all. Seven patients were readmitted in septic shock, but rapidly recovered. Two other patients died, one due to an irreversible shock within 12 hours of readmission and one due to bacterial meningitis within 48 hours after readmission. In 10 cases of rehospitalization, patients responded to the fi rst line of antibiotics. In the second group of the patients, only 2 courses of consolidation from a total of 15 were not complicated. In contrast to the fi rst group, we detected only poor effectiveness of broad-spectrum antibiotics in the group of inpatients. Conclusions: For AML patients in a good clinical status without any complicating medical conditions, the early discharge is feasible, safe and cost saving option (Tab. 2, Fig. 2, Ref. 7).

We evaluated responses to the treatment and long-term outcomes of chronic myeloid leukemia patients treated with imatinib as first-line treatment in routine clinical setting from two countries with centralized tyrosine kinase inhibitors (TKIs) treatment. We assessed prognostic significance of European LeukemiaNet (ELN) 2006- and 2009-defined responses and the prognostic value of molecular responses at defined time points on 5-year survivals. Among the cumulative rates of incidence of hematologic, cytogenetic, and molecular responses and all important survival parameters, we evaluated the prognostic significance of different BCR-ABL transcript-level ratios (≤1%; >1%–≤10%; >10%) at 3, 6, 12, and 18 months (n = 199). The ELN optimal response criteria and their predictive role were significantly beneficial for event-free survival at all given time points. We found significant improvement in survivals of patients with BCR-ABL lower than 10% in the 6th and 12th months. Significantly better outcome was found in patients who achieved major molecular response (MMR) in the 12th month. The cumulative incidences of complete cytogenetic response (CCyR) and MMR were significantly associated with the molecular response in the 3rd month. The ELN response criteria and their predictive role were helpful at given time points; however, the 2009 definition did not significantly alter the prognostic accuracy compared with that of the 2006 definition. The significant value was observed for cytogenetic responses at the 6th and 12th month. Moreover, progression-free and event-free survivals were improved with MMR at the 12th month.

Background: the role of autologous stem cell transplantation (ASCT) in treatment of acute myeloid leukemia (AML) remains unsettled. Aims: retrospective analysis to evaluate the role of ASCT in patients with AML without HLA-matched donor. Methods: between December 19, 1994 and August 1, 2012, a total of 63 patients with AML without HLA-matched donor in the department of Hematology and Transfusion Medicine, University Hospital, Bratislava, received an ASCT. Median age was 41 years (20-61 years). There were 35 (56%) males and 28 (44%) females. At the time of ASCT, 50 (79%) patients were in first complete remission (CR), 11 (18%) patients were in second CR and 2 (3%) patients were in relapse. Results: with a median follow-up of 115 months (34-214 months), the 10 year overall survival (OS) and disease free survival (DFS) of all patients was 55% and 51%, respectively. Transplant-related mortality was 6%. The relapse rate was 38% and 9 years probability of relapse was 44%. Conclusion: ASCT is still an effective post-remission treatment in AML patients without HLA-matched donor; with the possibility of long-term survival or even cure in remarkable proportion of patients with AML, particularly in patients with favorable and intermediate cytogenetic risk.

Using the data of 723 chronic myeloid leukemia (CML) patients in the chronic phase, we analyzed the prognostic value of the Sokal, Euro, and EUTOS scores as well as the level of BCR-ABL1 and the achievement of complete cytogenetic response (CCgR) at 3 months of imatinib therapy in relation to the so-called current survival measures: the current cumulative incidence (CCI) reflecting the probability of being alive and in CCgR after starting imatinib therapy; the current leukemia-free survival (CLFS) reflecting the probability of being alive and in CCgR after achieving the first CCgR; and the overall survival. The greatest difference between the CCI curves at 5 years after initiating imatinib therapy was observed for the BCR-ABL1 transcripts at 3 months. The 5-year CCI was 94.3% in patients with BCR-ABL1 transcripts 10% and 57.1% in patients with BCR-ABL1 transcripts > 10% (P 5 0.005). Therefore, the examination of BCR-ABL1 transcripts at 3 months may help in early identification of patients who are likely to perform poorly with imatinib. On the other hand, CLFS was not significantly affected by the considered stratifications. In conclusion, our results indicate that once the CCgR is achieved, the prognosis is good irrespective of the starting prognostic risks. Am. J.
