Here, we describe a patient diagnosed with chronic myelogenous leukemia who relapsed after matched unrelated donor SCT. The patient was treated with imatinib mesylate and donor lymphocyte infusions, and achieved a complete molecular remission. Additionally, safety and efficacy of imatinib mesylate in a total of 134 patients from 8 centers who underwent allogeneic or syngeneic stem cell transplantation (SCT) and had a relapse of Philadelphia chromosome positive leukemia was reviewed. Data was compiled from abstracts accepted as oral or poster presentations at the ASH (American Society of Hematology) 2001 and EBMT (European Group for Blood and Marrow Transplantation) 2001 & 2002 meetings and additionally literature published on this patient group. Efficacy of imatinib therapy was assessed by morphology, cytogenetic analysis, and determination of donor chimerism. In the evaluable population, hematologic and cytogenetic responses were observed in 66% and 60% of the patients, respectively. Fifty-one of 114 (45%) patients achieved a complete cytogenetic response. No response or progress of disease was noted in 22 out of evaluable 91 patients. The observation period was limited to a maximum of 28 months. A significant improvement in donor chimerism was frequently observed. Only five cases of significant GVHD were reported. Preliminary results show that imatinib mesylate has the potential to positively influence the ratio of donor and recipient cells without inducing a high incidence of severe GVHD. The data suggest that earlier start of imatinib mesylate prior to hematologic relapse in minimum residual disease (MRD) positive patients is a promising treatment concept.

This review is based on the deliberations at the 5th John Goldman Colloquium held in Estoril on 2nd October 2015 and the 9th post-ASH International Workshop on chronic myeloid leukemia (CML) and BCR-ABL1-negative myeloproliferative neoplasms (MPN) which took place on the 10th-11th December 2014, immediately following the 56th American Society of Hematology Annual Meeting. It has been updated since and summarizes the most recent advances in the biology and therapy of these diseases, in particular updates of genetics of MPN, novel insights from mouse MPN models, targeting CML stem cells and its niche; clinical advances include updates on JAK2 inhibitors and other therapeutic approaches to BCR-ABL1-negative MPNs, the use of alpha interferons, updates on tyrosine kinase inhibitors (TKI) randomized trials in CML, TKI cessation studies, and optimal monitoring strategies.

This review is based on the presentations and deliberations at the 7th John Goldman Chronic Myeloid Leukemia (CML) and Myeloproliferative Neoplasms (MPN) Colloquium which took place in Estoril, Portugal on the 15th October 2017, and the 11th post-ASH International Workshop on CML and MPN which took place on the 6th-7th December 2016, immediately after the 58th American Society of Hematology Annual Meeting. Rather than present a resume of the proceedings, we have elected to address some of the topical translational research and clinically relevant topics in greater detail. We address recent updates in the genetics and epigenetics of MPN, the mechanisms of transformation by mutant calreticulin, advances in the biology and therapy of systemic mastocytosis, clinical updates on JAK2 inhibitors and other therapeutic approaches for patients with MPNs, cardiovascular toxicity related to tyrosine kinase inhibitors and the concept of treatment-free remission for patients with CML.

Following the 47th American Society of Hematology Meeting in 2005, the late John Goldman and Tariq Mughal commenced a conference, the 1st Post-ASH Workshop, which brought together clinicians and scientists, to accelerate the adoption of new therapies for patients with myeloproliferative neoplasms (MPNs). The concept began with recognition of the CML success story following imatinib therapy, the discovery of JAK2V617F , and the demonstration that BCR-ABL1-negative MPNs are driven by abnormal JAK2 activation. This review is based on the presentations and deliberations at the XIIth Post-ASH Workshop on BCR-ABL1 positive and negative MPNs that took place on December 12 to 13, 2017, in Atlanta, Georgia, immediately following the 59th American Society of Hematology Meeting. We have selected some of the translational research and clinical topics, rather than an account of the proceedings. We discuss the role of immunotherapy in MPNs and the impact of the mutational landscape on TKI treatment in CML. We also consider how we might reduce TKI cardiovascular side effects, the potential role of nutrition as adjunctive nonpharmacologic intervention to reduce chronic inflammation in MPNs, and novel investigational therapies for MPNs.

Introduction: Tyrosine kinase inhibitors (TKIs), which target BCR-ABL1 kinase activity, have significantly prolonged the overall survival of patients affected by chronic myeloid leukemia (CML) and changed drastically the outcome. Evidences from several studies suggest that in patients who have achieved a sustained, stable and deep molecular response, TKI treatment can be safely discontinued with a close subsequent monitoring. Thus, a stable deep molecular response (DMR) has become a feasible treatment goal in CML. Areas covered: In this review, the main findings extrapolated from sponsored and real-life evidences regarding TKI discontinuation were discussed, through a broad research on Medline, Embase and archives from EHA and ASH congresses (including words such as discontinuation, treatment-free remission, TFR, etc). Moreover, suggestions emerged from international guidelines about treatment-free remission (TFR) are presented. Expert opinion: With the growing availability of clinical trials and real-life data on TFR, in recent years the possibility of offering to CML patients a safe, informed and shorter path to TFR, through the achievement of a stable deep molecular response (DMR), has become an increasing option. However, many controversial aspects remain regarding treatment choices and timings, predictive factors, patient communication and optimal strategies aimed at achieving a successful TFR.
