Dysregulation of immune cell and cytokine signalling correlates with clinical outcomes in myelodysplastic syndrome (MDS).

Objectives: Myelodysplastic syndromes (MDS) are characterised by ineffective haematopoiesis. Although hypomethylating agents (HMA) have improved survival in higher-risk MDS, most patients eventually succumb to progressive disease. Utilising samples collected prospectively from three MDS clinical trials, we analysed genetic and immunological biomarkers and correlated them with clinical outcomes.

Hemoglobin is a key determinant of quality of life before and during azacitidine-based therapy for myelodysplasia and low blast count acute myeloid leukemia.

Myelodysplastic syndromes (MDS) have a major impact on quality of life (QoL). We performed a analysis of two multicenter trials of azacitidine-based disease-modifying therapy for patients with MDS and low blast count acute myeloid leukemia (AML), to identify factors associated with QoL. 231 patients were included (median age 70 years).

A feasibility and acceptability study of an adaptation of the Mindful Self-Compassion program for adult cancer patients.

Objectives: Psychosocial interventions that mitigate psychosocial distress in cancer patients are important. The primary aim of this study was to examine the feasibility and acceptability of an adaptation of the Mindful Self-Compassion (MSC) program among adult cancer patients. A secondary aim was to examine pre-post-program changes in psychosocial wellbeing.

Phase 3 study of subcutaneous bortezomib, thalidomide, and prednisolone consolidation after subcutaneous bortezomib-based induction and autologous stem cell transplantation in patients with previously untreated multiple myeloma: the VCAT study.

Efficacy and safety of bortezomib-based consolidation following ASCT were investigated in newly diagnosed multiple myeloma patients from Australia, Korea, and China. Patients received three cycles of bortezomib-cyclophosphamide-dexamethasone induction followed by high-dose therapy/ASCT, then were randomized (1:1) to consolidation with TP (thalidomide 100 mg/d for ≤12 months/until disease progression; prednisolone 50 mg on alternate days indefinitely/until disease progression;  = 100) or VTP (subcutaneous bortezomib 1.3 mg/m every 2 weeks for 32 weeks, plus TP;  = 103).

Azacitidine with or without lenalidomide in higher risk myelodysplastic syndrome & low blast acute myeloid leukemia.

Standard treatment for higher risk myelodysplastic syndromes, chronic myelomonocytic leukemia and low blast acute myeloid leukemia is azacitidine. In single arm studies, adding lenalidomide had been suggested to improve outcomes. The ALLG MDS4 phase II trial randomized such patients to standard azacitidine or combination azacitidine (75mg/m/d days 1 to 5) with lenalidomide (10mg days 1-21 of 28-day cycle from cycle 3) to assess clinical benefit (alive without progressive disease) at 12 months.

Results of a phase II study of thalidomide and azacitidine in patients with clinically advanced myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML) and low blast count acute myeloid leukemia (AML).

Single agent azacitidine or immunomodulatory drugs are effective in myelodysplastic syndrome (MDS), with differing target mechanisms and toxicities. Objectives of this ALLG MDS3 study in clinically advanced MDS, AMML and low blast AML were to establish safety, response and quality of life of azacitidine and thalidomide. Patients received azacitidine (75mg/m/d sc 7days every 28 days), and oral thalidomide up to 100mg/d for maximum 12months.

Epigenetic targets in hematological malignancies: combination therapies with HDACis and demethylating agents.

Chromatin modeling in DNA is fundamental to gene expression, DNA repair and replication. Methylation of promoter regions of tumor-suppressor genes and histone deacetylation leads to gene silencing and transcriptionally repressive chromatin. Histone deacetylase inhibitors and hypomethylating agents allow upregulation of proapoptotic genes and downregulation of antiapoptotic genes, and show significant single-agent anticancer activity, predominantly in cutaneous T-cell lymphoma and myelodysplasia, respectively.

Treatment-related myelodysplasia following fludarabine combination chemotherapy.

Although myelodysplasia (MDS) and secondary acute myeloid leukemia (sAML) are rare following fludarabine monotherapy, the risk of these diseases may potentially be increased when fludarabine is combined with cyclophosphamide or mitoxantrone due to synergistic effects on the inhibition of DNA repair. Among 137 patients treated with fludarabine combination regimens, ten patients developed MDS/sAML, including one who had received no other therapy. Six patients had abnormalities of chromosomes 5 and/or 7.

Safety and efficacy of pegfilgrastim compared to granulocyte colony stimulating factor (G-CSF) supporting a dose-intensive, rapidly cycling anti-metabolite containing chemotherapy regimen (Hyper-CVAD) for lymphoid malignancy.

Pegfilgrastim (Neulasta) has proven efficacy as supportive therapy in a variety of 21-day chemotherapy regimens, but has not been studied in dose intensive, rapidly cycling regimens utilising cell-cycle active drugs (e.g. anti-metabolites) such as hyper-CVAD.
