- The first Team Haemophilia Education (THE) Meeting was held on 7–8 May 2015 in Amsterdam, The Netherlands. It aimed to promote the optimal care of patients with haemophilia through education of the multidisciplinary treatment team. This was achieved by reviewing the latest developments in haemophilia management, considering how these can be implemented in the clinic to improve patient care and providing a platform for networking and debate for all haemophilia treatment team members. The second THE Meeting was held on 19–20 May in Frankfurt, Germany, and participants included doctors, nurses, physiotherapists, patient representatives and data management staff from 20 different countries. Topics covered the role of the multidisciplinary team in delivering the best haemophilia care, challenges in the management of haemophilia across Europe, available clotting factor treatments, future treatments and the use of genetics in advising carriers of haemophilia. This report is a summary of the key developments in haemophilia care presented by various investigators and healthcare professionals at THE Meeting 2016.

Tidskriftsartikel (refereegranskat)abstract
- Multiple myeloma (MM) is a B-cell malignancy characterized by the expansion of clonal plasma blasts/plasma cells within the bone marrow that relies on multiple signaling cascades, including tyrosine kinase activated pathways, to proliferate and evade cell death. Despite emerging new treatment strategies, multiple myeloma remains at present incurable. Thus, novel approaches targeting several signaling cascades by using the multi-tyrosine kinase inhibitor (TKI), sorafenib, seem a promising treatment approach for multiple myeloma. Here, we show that sorafenib induces cell death in multiple myeloma cell lines and in CD138(+)-enriched primary multiple myeloma patient samples in a caspase-dependent and -independent manner. Furthermore, sorafenib has a strong antitumoral and -angiogenic activity in the 5T33MM mouse model leading to increased overall survival. Multiple myeloma cells undergo autophagy in response to sorafenib, and inhibition of this cytoprotective pathway potentiated the efficacy of this TKI. Mcl-1, a survival factor in multiple myeloma, is downregulated at the protein level by sorafenib allowing for the execution of cell death, as ectopic overexpression of this protein protects multiple myeloma cells. Concomitant targeting of Mcl-1 by sorafenib and of Bcl-2/Bcl-xL by the antagonist ABT737 improves the efficacy of sorafenib in multiple myeloma cell lines and CD138(+)-enriched primary cells in the presence of bone marrow stromal cells. Altogether, our data support the use of sorafenib as a novel therapeutic modality against human multiple myeloma, and its efficacy may be potentiated in combination with ABT737.

Cell death mechanisms of anti-cancer agents and treatment response in acute leukemia
- 2006

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Acute leukemia (AL) is a fatal disease, which causes rapid death in the absence of appropriate chemotherapeutic intervention. Long-term survival rates vary from 80% in childhood lymphoblastic AL (ALL) to 10-20% in adult myeloid AL (AML). Failures to achieve complete remission (CR) and relapses are mainly due to chemoresistance of the malignant cells. In this thesis, the molecular mechanisms of cell death as induced by two antileukemia agents, doxorubicin (DXR) and the glucocorticoid dexamethasone (Dex), were investigated. The monitoring of malignant cell clearance from the bone marrow of patients during treatment for leukemia complements molecular studies with the main goal of improving prognosis in AL. Finally, pre- and post-chemotherapy levels of dendritic cells (M) were examined. DCs constitute a complex system orchestrating the immune response but have not been extensively studied in AL patients. Sequentially activated caspase-2, PKCδ and JNK were defined as the key components in DXR-induced apoptosis in AL (Paper 1). Dex-induced cell death in ALL cell lines and primary leukemia cells was found to occur through P13K/Akt-dependent autophagy: a novel caspase-independent cell death pathway. There was a positive correlation between ex vivo Dex-sensitivity of ALL blasts and an early treatment response of patients with ALL (Paper 11). Young adult AML patients, who have detectable minimal residual disease at the first CR and/or at the end of post-remission chemotherapy, were demonstrated to have a dismal prognosis and to benefit from stem cell transplantation (Paper III). Children with ALL at diagnosis were found to have a profound deficiency of DCs. This deficiency was more severe in B-ALL than in T-ALL. The myeloid DC subset was affected by cytostatic therapy more than the plasmocytoid DC subset (Paper IV). Studies included this thesis may help to refine the selection of individual therapeutic strategies in the treatment of AL patients and thus to improve long-term outcome. The study also elucidates some mechanisms of drug resistance and identifies new prognostic factors for AL patients.

Tidskriftsartikel (refereegranskat)abstract
- The Nordic Myeloma Study Group conducted an open randomized trial to compare bortezomib as consolidation therapy given after high-dose therapy and autologous stem cell transplantation (ASCT) with no consolidation in bortezomib-naive patients with newly diagnosed multiple myeloma. Overall, 370 patients were centrally randomly assigned 3 months after ASCT to receive 20 doses of bortezomib given during 21 weeks or no consolidation. The hypothesis was that consolidation therapy would prolong progression-free survival (PFS). The PFS after randomization was 27 months for the bortezomib group compared with 20 months for the control group (P = .05). Fifty-one of 90 patients in the treatment group compared with 32 of 90 controls improved their response after randomization (P = .007). No difference in overall survival was seen. Fatigue was reported more commonly by the bortezomib-treated patients in self-reported quality-of-life (QOL) questionnaires, whereas no other major differences in QOL were recorded between the groups. Consolidation therapy seemed to be beneficial for patients not achieving at least a very good partial response (VGPR) but not for patients in the andgt;= VGPR category at randomization. Consolidation with bortezomib after ASCT in bortezomib-naive patients improves PFS without interfering with QOL. This trial was registered at www.clinicaltrials.gov as #NCT00417911.

- Estonia regained independence in 1991 after five decades of occupation by the Soviet Union. The present population-based survey was carried out over five consecutive 5-year study periods (1982-2006) on the incidence and survival of de novo acute leukemia patients aged ≥65 years at diagnosis in Estonia and in a well-defined area in western Sweden. During the study period of retrospective work (1982-1996), the first 10 years were carried out while Estonia was still under the mentorship of the Soviet Union. Over these years, Estonian hematologists did not have access to therapeutic measures readily available to Swedish hematologists, and the results for survival for western Swedish patients with acute myeloid leukemia (AML) far exceeded those of their Estonian counterparts. However, the results for acute lymphoblastic leukemia were equally dismal in the two countries. Subsequent prospective population-based studies were carried out during the years 1997-2006. A gradual improvement as to long-term relative survival of the Estonian AML patients was observed. When studying 2002-2006, no difference as regards relative survival at 5 years was anymore present between the two countries. Over the first 20 years of our population-based studies, it was repeatedly observed that the age-standardized incidence rate particularly for de novo AML was considerably higher for the western Swedish as compared to the Estonian cohorts. During the last 5-year study period (2002-2006), no such difference between the two countries was present, indicating that some true changes in the reporting procedure in Estonia had occurred.
