Allogeneic hematopoietic stem cell transplantation in therapy-related myeloid neoplasms (t-MN) of the adult: Monocentric observational study and review of the literature

Background: Therapy related myeloid neoplasms (t-MN) occur due to direct mutational events of chemotherapeutic agents and radiotherapy. Disease latency, mutational events and prognosis vary with drugs categories. Methods: We describe a cohort of 30 patients, 18 females and 12 males, with median age of 52.5 years (range, 20 to 64), submitted to allogeneic stem cell transplantation (HSCT) in our department between September 1999 and March 2017. Patients had a history of solid tumour in 14 cases, haematological disease in 15 cases and both of them in one case. After a median of 36.5 months (range, 4 to 190) from first neoplasm, patients developed t-AML in 19 cases and t-MDS in 11 cases. Molecular abnormalities were detected in 5 patients, while karyotype aberrations were found in 17 patients. Patients received conventional chemotherapy in 14 cases, azacitidine in 10 cases and both of them in one case. Five patients were submitted to HSCT without previous treatment except for supportive therapy. Results: Seventeen patients obtained sustained CR after SCT, while 8 patients showed resistant or relapsed disease. The remaining five patients died early after SCT. At follow up time (May 2017) 13 patients were alive with a median OS of 48 months (range 3-195), while 17 patients died after a median of 4 months (range 1-27) by relapse mortality in 6 cases and non-relapse mortality in the other 11 patients. Conclusions: Global OS was 43%. After SCT, 72.2% of patients with t-MN maintained a sustained CR

Role of flow-cytometric immunophenotyping in prediction of BCR/ABL1 gene rearrangement in adult B-cell acute lymphoblastic leukemia

We performed a retrospective analysis of 88 adult patients with B-ALL diagnosed in our center by a flow-cytometric assessment. Immunophenotypic expression of leukemic cells was explored by simultaneous evaluation of positivity, percentage of expressing cells and median fluorescence intensity (MFI). BCR/ABL1 fusion transcripts were assessed by RT-PCR analysis and were identified in 36 patients (40.9%). CD10 and CD34 were positive in the totality of BCR/ABL1-positive cases. Patients with gene rearrangement had a greater frequency of CD66c, CD13 and CD33 positivity compared with BCR/ABL1-negative cases. Moreover, BCR/ABL1-positive cases exhibited a greater median percentage and MFI values of CD13, CD33, CD66c, CD10, CD34 and CD25 expressions, but a lower median percentage and MFI values of CD38 and CD22 expressions than patients without gene rearrangement. Multivariate logistic regression analysis showed that CD10, CD38 and CD13 expressions were independent predictors for the presence of BCR/ABL1 rearrangement. Predictive probabilities of molecular occurrence based on these markers are proposed. \ua9 2017 International Clinical Cytometry Society

Autologous peripheral blood stem cell transplantation and the role of lenalidomide in patients affected by poems syndrome

POEMS syndrome is a rare paraneoplastic condition, with a poorly understood pathogenesis. High dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been reported to be an effective therapeutic option for patients with good performance status. Here, we review the role of ASCT for POEMS syndrome and discuss indications together with advantages and disadvantages, and related issues such lenalidomide given before or after ASCT, VEGF levels as a marker of disease, and different regimens for stem cell mobilization
