BACKGROUND: Previous studies on occupational exposures in parents and cancer risks in their children support a link between solvents and paints with childhood leukaemia. Few studies have focused specifically on benzene. OBJECTIVES: To examine whether parental occupational exposure to benzene is associated with an increased cancer risk in a census-based cohort of children. METHODS: From a census-based cohort study in Switzerland, we included children aged <16years at national censuses (1990, 2000)...

In children with newly diagnosed acute myeloid leukaemia (AML), myeloid sarcomas (MS) of the central nervous system (CNS) are rare. Since MS involving the CNS are potentially curable, timely recognition is paramount. Establishing a diagnosis may be problematic as they can easily mimic primary CNS neoplasms. We report the case of a 5-year-old boy with AML with t(8;21)(q22;q22) rearrangement who presented with a massive intracranial MS and rapid clinical deterioration suggestive of a meningioma or a primitive neuroectodermal tumour...

WHAT IS KNOWN AND OBJECTIVE: Voriconazole and vincristine are major therapeutics in paediatric haematology. However, the risk-benefit ratio of the treatment of invasive aspergillosis with voriconazole in patients receiving vincristine-based chemotherapy remains unclear. CASE DESCRIPTION: We report severe peripheral and central neurological disorders in a 14-year-old girl with T-cell acute lymphoblastic leukaemia and pulmonary aspergillosis. The case describes a strong exacerbation by voriconazole of the vincristine-induced neuropathic pains...

REVIEW
Chin-Hin Ng, Wee-Joo Chng
Acute promyelocytic leukaemia (APML) is a subtype of leukaemia arising from a distinct reciprocal translocation involving chromosomes 15 and 17, which results in the PML-RARA fusion gene. Over the past three decades, APML has been transformed from a highly fatal disease to a highly curable one. This drastic improvement is because of the introduction of a new treatment strategy with all-trans retinoic acid and, more recently, arsenic trioxide. The revolutionary treatment of APML has also paved the way for a new cancer treatment, which is genetically targeted therapy...

Neutropenic infections are life-threatening and require empiric antibiotic treatment. We examined 1139 blood culture isolates from our institution over a 36-year period from neutropenic patients to examine temporal trends and disease associations. Positive associations were found between viridans streptococci and acute myeloid leukaemia, coagulase negative staphylococci and acute lymphoblastic leukaemia and Pseudomonas aeruginosa and indolent B-cell malignancies.

WHAT IS KNOWN AND OBJECTIVE: Several studies have reported that itraconazole-induced inhibition of vincristine (VCR) metabolism might result in neurological impairment and syndrome of inappropriate antidiuretic hormone (SIADH). However, there are few reports concerning adverse drug reactions (ADRs) resulting from concomitant use of vindesine (VDS) and itraconazole. Here, we report the first case of adverse drug interactions (ADIs) between itraconazole and VDS in a Chinese child with acute lymphocytic leukaemia (ALL)...

The prognosis in children with refractory or relapsed (r/r) T-cell acute lymphoblastic leukaemia (T-ALL) or lymphoblastic lymphoma (T-LBL) is poor. Nelarabine (Ara-G) has successfully been used as salvage therapy in these children, but has been associated with significant, even fatal, neurotoxicities. We retrospectively analysed 52 patients with r/r T-ALL/T-LBL aged ≤19 years who were treated with Ara-G alone (n = 25) or in combination with cyclophosphamide and etoposide (n = 27). The majority of patients (45/52) received 1-2 cycles of Ara-G...

BACKGROUND: Multi-drug resistant (MDR) bacteria are associated with increased morbidity and mortality in children with acute leukaemia. The present study was conducted to assess the prevalence of MDR bacteria in stool cultures of patients with acute leukaemia at presentation to the hospital. The results were then correlated with blood cultures when patients developed septicaemia. PATIENTS AND METHODS: The study involved analysis of case records of patients with newly diagnosed acute leukaemia less than 18 years of age treated at our centre from January 2015 to December 2015...

Genomic transposable elements (TEs) comprise nearly half of the human genome. The expression of TEs is considered potentially hazardous, as it can lead to insertional mutagenesis and genomic instability. However, recent studies have revealed that TEs are involved in immune-mediated cell clearance. Hypomethylating agents can increase the expression of TEs in cancer cells, inducing 'viral mimicry', causing interferon signalling and cancer cell killing. To investigate the role of TEs in the pathogenesis of acute myeloid leukaemia (AML), we studied TE expression in several cell fractions of AML while tracking its development (pre-leukemic haematopoietic stem cells, leukemic stem cells [LSCs], and leukemic blasts)...

OBJECTIVES: According to the American Society of Clinical Oncology palliative care referrals are made within the last 3 weeks of patients' lives and most frequently when oncological treatments have ceased especially for patients with haematological malignancies. Recent publications indicate that patients with acute leukaemia are prone to symptoms, an indication for which a close collaboration between the patient's haematologist and a palliative care team might result in improved symptom management...

BACKGROUND: Olaparib, a poly(ADP-ribose) polymerase (PARP) inhibitor, has previously shown efficacy in a phase 2 study when given in capsule formulation to all-comer patients with platinum-sensitive, relapsed high-grade serous ovarian cancer. We aimed to confirm these findings in patients with a BRCA1 or BRCA2 (BRCA1/2) mutation using a tablet formulation of olaparib. METHODS: This international, multicentre, double-blind, randomised, placebo-controlled, phase 3 trial evaluated olaparib tablet maintenance treatment in platinum-sensitive, relapsed ovarian cancer patients with a BRCA1/2 mutation who had received at least two lines of previous chemotherapy...

We retrospectively investigated outcomes of haploidentical donor (HID) transplant for adults with standard-risk acute lymphoblastic leukaemia (ALL) in first complete remission (CR1) compared with human leucocyte antigen (HLA)-matched sibling donor (MSD) and HLA-matched unrelated donor (MUD) transplants. A total of 348 adult patients were enrolled, including 127 HID, 144 MSD and 77 MUD recipients. The cumulative incidence of grade II-IV acute graft-versus-host disease (aGVHD) was 39·5%, 24·0% and 40·3% for HID, MSD and MUD, respectively (P = 0·020)...

8-chloro-adenosine (8-Cl-Ado) is currently in phase-I clinical trials for acute myeloid leukaemia and chronic lymphocytic leukaemia (CLL). Previously, we demonstrated that treatment with 8-Cl-Ado leads to diminished ATP levels. We hypothesized that AMP-activated protein kinase (AMPK) signalling would be initiated in these cells, leading to induction of autophagy. AMPK activation and induction of autophagy were demonstrated during preclinical incubations in CLL cells with the analogues. Importantly, we extended similar observations in CLL lymphocytes during an 8-Cl-Ado phase-I trial...

The incidence of invasive fungal infections (IFI) is believed to be higher in patients with acute myeloid leukaemia (AML) undergoing chemotherapy in non-HEPA-filtered rooms. The aim of this study is to review the incidence of IFI in a large cohort of patients with AML treated at a single centre in India. Two hundred and twenty-two patients with AML treated with either induction chemotherapy or salvage chemotherapy between 2008 and 2013 were studied retrospectively. IFI was defined as per the revised EORTC-MSG criteria...

BACKGROUND: Survival for childhood acute lymphoblastic leukaemia surpasses 90% with contemporary therapy; however, patients remain burdened by the severe toxic effects of treatment, including asparaginase-associated pancreatitis. To investigate the risk of complications and risk of re-exposing patients with asparaginase-associated pancreatitis to asparaginase, 18 acute lymphoblastic leukaemia trial groups merged data for this observational study. METHODS: Patient files from 26 trials run by 18 trial groups were reviewed on children (aged 1·0-17·9 years) diagnosed with t(9;22)-negative acute lymphoblastic leukaemia between June 1, 1996, and Jan 1, 2016, who within 50 days of asparaginase exposure developed asparaginase-associated pancreatitis...

The ever increasing pace of development of novel therapies mandates efficient methodologies for assessment of their tolerability and activity. Evidence increasingly support the merits of model-based dose-finding designs in identifying the recommended Phase II dose compared to conventional rule-based designs such as the 3+3 but despite this, their use remains limited. Here, we propose a useful tool, Dose Transition Pathways (DTP), which helps overcome several commonly-faced practical and methodological challenges in the implementation of model-based designs...
