Australia and New Zealand Transplant and Cellular Therapies (ANZTCT) position statement: COVID-19 management in patients with haemopoietic stem cell transplant and chimeric antigen receptor T cell.

Patients with post-haemopoietic stem cell transplant or chimeric antigen receptor T -cell (CAR-T) therapy face a significant risk of morbidity and mortality from coronavirus disease 2019 because of their immunosuppressed state. As case numbers in Australia and New Zealand continue to rise, guidance on management in this high-risk population is needed. Whilst we have learned much from international colleagues who faced high infection rates early in the pandemic, guidance relevant to local health system structures, medication availability and emerging therapies is essential to equip physicians to manage our patients optimally.

Activity and outcomes of autologous stem cell transplantation in the private sector in Australia.

Background: Few Australasian autologous stem cell transplantation (ASCT) programmes perform ASCT in the private sector. Relatively little is known about ASCT outcomes in the private sector, which varies in care delivery models to the public system.

Aims: To investigate transplantation activity and survival outcomes at Icon Cancer Centre's Brisbane-based private clinical and laboratory ASCT programme over a 23-year period.

A comprehensive study of the epidemiology of haematological malignancies in North Queensland.

Background: There is an absence of clinically relevant epidemiological data in regional Australia pertaining to haematological malignancies.

Aim: To determine the incidence and geographical variation of haematological malignancies in North Queensland using a clinically appropriate disease classification.

Methods: Retrospective, observational study of individual patient data records of all adults diagnosed with a haematological malignancy between 2005 and 2014 and residing within The Townsville Hospital Haematology catchment region.

An MRD-stratified pediatric protocol is as deliverable in adolescents and young adults as in children with ALL.

Pediatric regimens have improved outcomes in adolescent and young adult (AYA) acute lymphoblastic leukemia (ALL). However, results remain inferior to children with ALL. The Australasian Leukaemia and Lymphoma Group (ALLG) ALL06 study (anzctr.

Australia and New Zealand Transplant and Cellular Therapies COVID-19 vaccination consensus position statement.

Australia and New Zealand have achieved excellent community control of COVID-19 infection. In light of the imminent COVID-19 vaccination roll out in both countries, representatives of all adult and paediatric allogeneic bone marrow transplant and cellular therapy (TCT) centres as well as representatives from autologous transplant only centres in Australia and New Zealand collaborated with infectious diseases specialists with expertise in TCT on this consensus position statement regarding COVID-19 vaccination in TCT patients in Australia and New Zealand. It is our recommendation that TCT patients, should have expedited access to high-efficacy COVID-19 vaccines given that these patients are at high risk of morbidity and mortality from COVID-19 infection.

Pralatrexate in relapsed/refractory T-cell lymphoma: a retrospective multicenter study.

We present a retrospective multicenter study of pralatrexate treatment outcomes in an Australian practice setting for patients with relapsed/refractory T-cell lymphoma who had failed 1+ systemic therapies, treated a compassionate access program. Endpoints assessed included response rates, toxicities, and subsequent therapies. Progression-free survival (PFS), time to next treatment (TTNT), event-free survival (EFS), overall survival (OS), and time to best response, were assessed by Kaplan-Meier analysis.

A consensus statement on the use of biosimilar medicines in hematology in Australia.

Despite their availability for over a decade, the exact nature of biosimilar medicines is still poorly understood with paucity of clear treatment guidelines for their use in clinical practice in Australia. Although hematologists have had experience with biosimilars in the setting of supportive care, with the approval of the first biosimilar rituximab in hematological malignancies, it is important to revisit this topic. To inform the use of biosimilar medicines in clinical practice, we have developed a consensus statement from an Expert Panel of Australian hematologists, oncologists, and cancer pharmacists.

A 14-year retrospective analysis of indications and outcomes of autologous haemopoietic stem cell transplantation in regional Queensland: a single-centre experience.

Background: The Townsville Hospital is a tertiary hospital in North Queensland with one of the largest regional transplant centres in Australia, performing primarily autologous haemopoietic stem cell transplants (HSCT) for various haematological malignancies.

Aims: This single-centre, retrospective, observational study aims to describe the activity and outcomes of autologous HSCT at The Townsville Hospital between 2003 and 2017 to verify safety standards.

Methods: Patient-level data were collected, including demographics, frequency and indication for transplant, conditioning, current clinical status and cause of death.

The relationship between CD34+ stem cell dose and time to neutrophil recovery in autologous haematopoietic stem cell recipients-A single centre experience.

A retrospective, observational study was performed of 112 patients who underwent autologous haematopoietic stem cell transplantation (ASCT) to determine the relationship between CD34+ stem cell dose and neutrophil engraftment. Importantly, a novel approach to more accurately calculate time to neutrophil engraftment was employed. The results demonstrated that a higher CD34+ stem cell dose was associated with faster neutrophil recovery (P < 0.

Efficacy and safety of nilotinib 300 mg twice daily in patients with chronic myeloid leukemia in chronic phase who are intolerant to prior tyrosine kinase inhibitors: Results from the Phase IIIb ENESTswift study.

Background: Some patients receiving a tyrosine kinase inhibitor (TKI) for the first-line treatment of chronic phase chronic myeloid leukemia (CML-CP) experience intolerable adverse events. Management strategies include dose adjustments, interrupting or discontinuing therapy, or switching to an alternative TKI.

Methods: This multicenter, single-arm, Phase IIIb study included CML-CP patients intolerant of, but responsive to, first-line treatment with imatinib or dasatinib.

FLT3-ITD positive acute myeloid leukemia: A retrospective analysis of the role of allogeneic transplant and allelic ratio in patient management.

Aim: FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) positive AML is associated with increased relapse risk and reduced overall survival (OS) compared to non-FLT3-mutated AML. The aim of this study was to evaluate the impact of allelic ratio and allogeneic transplant on outcomes in FLT3-ITD+ AML.

Methods: A retrospective study across five centers in Queensland, Australia, was conducted to examine survival outcomes and impact of FLT3-ITD allelic ratio and allograft.

Effects of intensive induction and consolidation chemotherapy with idarubicin and high dose cytarabine on minimal residual disease levels in newly diagnosed adult precursor-B acute lymphoblastic leukemia.

An intensive induction regimen, consisting of idarubicin and high dose cytarabine, was assessed in 19 adult patients, median age 44 years, with newly diagnosed precursor-B acute lymphoblastic leukemia (ALL). Patients achieving a complete response (CR) were given an attenuated consolidation course. The primary endpoints were induction death rate and incidence of serious non-hematological toxicity.

Screening whole spine magnetic resonance imaging in multiple myeloma.

Background: Magnetic resonance imaging (MRI) is the most sensitive method for detecting focal spinal disease (FSD) in multiple myeloma (MM). It is unclear whether whole spine MRI (WS-MRI) should be employed as a screening test at diagnosis of MM.

Aim: To determine the utility of screening WS-MRI at diagnosis of MM.

An imatinib-only window followed by imatinib and chemotherapy for Philadelphia chromosome-positive acute leukemia: long-term results of the CMLALL1 trial.

We report long-term results in 40 patients with Philadlephia chromosome-positive (Ph+) acute leukemia who received an imatinib monotherapy window to evaluate in vivo effects on BCR-ABL signaling prior to induction chemotherapy. The first 25 patients (cohort 1) received the LALA-94 protocol without further imatinib (newly diagnosed Ph+ acute lymphoblastic leukemia [ALL]) or induction chemotherapy followed by single-agent imatinib. Subsequent patients (cohort 2) continued imatinib concurrently with either LALA-94 (newly diagnosed Ph + ALL) or other intensive chemotherapy regimens.

Excellent outcomes for adolescents and adults with acute lymphoblastic leukemia and lymphoma without allogeneic stem cell transplant: the FRALLE-93 pediatric protocol.

Adolescents and adults with acute lymphoblastic leukemia/lymphoma (ALL) have better outcomes when treated using pediatric protocols compared with treatment using adult protocols. We reviewed the progress and outcomes of 40 adolescents and adults up to 45 years of age, from three Australian centers, treated on the intensive French group for childhood ALL (FRALLE)-93 pediatric protocol. All except one patient achieved a morphologic complete remission following induction chemotherapy.

Chronic myeloid leukemia in the Asia-Pacific region: current practice, challenges and opportunities in the targeted therapy era.

Chronic myeloid leukemia (CML) management varies across Asia due to disparities in affluence and healthcare provision. We surveyed CML management practice at 33 hospitals in 14 countries/regions to identify treatment challenges and opportunities for harmonization. Patients were generally treated according to international guidelines; however, tyrosine kinase inhibitors (TKIs) and molecular monitoring are inaccessible to many patients not covered by national insurance or eligible for subsidized treatment.

The effect of adjunctive fresh frozen plasma administration on coagulation parameters and survival in a canine model of antivenom-treated brown snake envenoming.

This study aimed to assess the effects of dugite envenoming on blood coagulation and platelet count in a canine model, and the efficacy of fresh frozen plasma (FFP) in reversing the clotting disorder after both adequate and inadequate venom neutralization. Following initial dosing and administration studies, an intravenous venom dose of 1 microg/kg was administered to eleven dogs. This was followed 30 minutes later by antivenom in either adequate or inadequate doses.

Hemoglobin Titusville, a low oxygen affinity variant hemoglobin, in a family of Northern European background.

We report the second case of Hb Titusville in a family of Northern European background. This variant hemoglobin caused by an alpha-globin gene mutation has decreased oxygen affinity. Correct diagnosis is clinically important to spare affected individuals extensive investigations into other causes of low oxygen saturation in peripheral blood.

Combination therapy with tacrolimus and anti-thymocyte globulin for the treatment of steroid-resistant acute graft-versus-host disease developing during cyclosporine prophylaxis.

We report our experience with the combination of anti-thymocyte globulin (ATGAM) and tacrolimus in the treatment of 20 patients with steroid refractory and dependent acute graft-versus-host disease (GVHD) transplanted between August 1996 and February 2000. All patients received cyclosporine-based GVHD prophylaxis. Thirteen patients developed a maximum of grade IV, five grade III and two grade II acute GVHD, with 15 patients being refractory to steroids and five dependent on steroids.

Sciatic nerve compression following bone marrow harvest.

We describe a donor who suffered pain secondary to sacral plexus and sciatic nerve compression post bone marrow harvest. Haematoma was demonstrated by magnetic resonance image (MRI) scanning. To our knowledge, this is the first reported case of compression neuropathy post bone marrow harvest documented by MRI scanning.
