Background: As physical function and physical activity are often compromised among children and adolescents undergoing acute cancer treatment, psychometrically robust and feasible assessment tools are needed. The aim of this study is to evaluate the construct validity, responsiveness and feasibility of one physical activity assessment tool (Fitbit Inspire); and six physical function assessment tools (Movement ABC-2, Timed Up and Go, 30-s Chair Stand, Timed Rise from the Floor, Timed Up and Down Stairs, 6-min Walk Test) for children undergoing acute cancer treatment. Methods: A prospectively-registered, mixed methods, single-group study evaluated measurement properties against a priori hypothesis using Consensus-based Standards for the selection of health status Measurement Instruments (COSMIN) framework. Feasibility was assessed quantitively (a priori thresholds), and qualitatively (semi-structured interviews, focus-groups). Results: Twenty children/adolescents (median age 13 ± 5 years, various cancer diagnoses), 20 parents and 16 clinicians participated. Fitbit was feasible to assess daily steps only, had evidence of construct validity, tendency to overestimate step count and adequate evidence of responsiveness (compared to Actigraph). The 30-s Chair stand, 6-min Walk Test and Timed Up and Go were feasible and showed evidence of construct validity and responsiveness. To maximise feasibility, consideration of timing and intent of assessment are crucial. Conclusion: Fitbit has limitations as a physical activity assessment tool. The 30-s Chair Stand, 6-min Walk Test and Timed Up and Go were feasible to use and showed favourable measurement properties to assess physical function.

Abstract Pharmacogenomics (PGx) investigates the influence of genetics on drug responses, enabling tailored treatments for personalized healthcare. This study assessed the accuracy of genotyping six genes using whole genome sequencing with four different computational tools and various sequencing depths. The effects of using different reference genomes (GRCh38 and GRCh37) and sequence aligners (BWA‐MEM and Bowtie2) were also explored. The results showed generally minor variations in tool performance across most genes; however, more notable discrepancies were observed in the analysis of the complex CYP2D6 gene. Cyrius, a CYP2D6‐specific tool, demonstrated the most robust performance, achieving the highest concordance rates for CYP2D6 in all instances, comparable to the consensus approach in most cases. There were rather small differences between the samples with 20× coverage depth and those with higher depth, but the decreased performance was more evident at lower depths, particularly at 5×. Additionally, variations in CYP2D6 results were observed when samples were aligned to different reference genomes using the same method, or to the same genome using different aligners, which led to reporting incorrect rare star alleles in several cases. These findings inform the selection of optimal PGx tools and methodologies as well as suggest that employing a consensus approach with two or more tools might be preferable for certain genes and tool combinations, especially at lower sequencing depths, to ensure accurate results. Additionally, we show how the upstream alignment can affect the performance of tools, an important factor to take into account.

Abstract For the same age, sex, and dosage, there can be significant variation in fertility outcomes in childhood cancer survivors. Genetics may explain this variation. This study aims to: (i) review the genetic contributions to infertility, (ii) search for pharmacogenomic studies looking at interactions of cancer treatment, genetic predisposition and fertility‐related outcomes. Systematic searches in MEDLINE Ovid, Embase Classic+Embase, and PubMed were conducted using the following selection criteria: (i) pediatric, adolescent, and young adult cancer survivors, below 25 years old at the time of diagnosis, (ii) fertility outcome measures after cancer therapy, (iii) genetic considerations. Studies were excluded if they were (i) conducted in animal models, (ii) were not published in English, (iii) editorial letters, (iv) theses. Articles were screened in Covidence by at least two independent reviewers, followed by data extraction and a risk of bias assessment using the Quality in Prognostic Studies tool. Eight articles were reviewed with a total of 29 genes. Outcome measures included sperm concentration, azoospermia, AMH levels, assessment of premature menopause, ever being pregnant or siring a pregnancy. Three studies included replication cohorts, which attempted replication of SNP findings for NPY2R, BRSK1, FANCI, CYP2C19, CYP3A4, and CYP2B6. Six studies were rated with a high risk of bias. Differing methods may explain a lack of replication, and small cohorts may have contributed to few significant findings. Larger, prospective longitudinal studies with an unbiased genome‐wide focus will be important to replicate significant results, which can be applied clinically.

Abstract Background Modern oncological therapies together with chemotherapy and radiotherapy have broadened the agents that can cause cardiac sequelae, which can manifest for pediatric oncology patients while on active treatment. Recommendations for high-risk patients who should be monitored in a pediatric cardio-oncology clinic have previously been developed by expert Delphi consensus by our group. In 2022 we opened our first multidisciplinary pediatric cardio-oncology clinic adhering to these recommendations in surveillance and management. Objectives Our pediatric cardio-oncology clinic aimed to: (i) Document cardiovascular toxicities observed within a pediatric cardio-oncology clinic and. (ii) Evaluate the applicability of the Australian and New Zealand Pediatric Cardio-Oncology recommendations. Methods Monthly multidisciplinary cardio-oncology clinics were conducted in an Australian tertiary pediatric hospital. Structured standardised approaches to assessment were built into the electronic medical record (EMR). All patients underwent baseline echocardiogram and electrocardiogram assessment together with vital signs in conjunction with standard history and examination. Results Nineteen (54%) individuals had a documented cardiovascular toxicity or pre-existing risk factor prior to referral. The two most common cardiovascular toxicities documented during clinic review included Left Ventricular Dysfunction (LVD) and hypertension. Of note 3 (8.1%) patients had CTCAE grade III LVD. An additional 10 (27%) patients reviewed in clinic had CTCAE grade I hypertension. None of these patients had hypertension noted within their referral. Cascade testing for cardiac history was warranted in 2 (5.4%) of patients. Conclusions Pediatric cardio-oncology clinics are likely beneficial to documenting previously unrecognised cardiotoxicity and relevant cardiac family histories, whilst providing an opportunity to address lifestyle risk factors.

Medicine - Abstract
Introduction DNA-informed prescribing (termed pharmacogenomics, PGx) is the epitome of personalised medicine. Despite international guidelines existing, its implementation in paediatric oncology remains sparse.Methods and analysis Minimising Adverse Drug Reactions and Verifying Economic Legitimacy-Pharmacogenomics Implementation in Children is a national prospective, multicentre, randomised controlled trial assessing the impact of pre-emptive PGx testing for actionable PGx variants on adverse drug reaction (ADR) incidence in patients with a new cancer diagnosis or proceeding to haematopoetic stem cell transplant. All ADRs will be prospectively collected by surveys completed by parents/patients using the National Cancer Institute Pediatric Patient Reported [Ped-PRO]-Common Terminology Criteria for Adverse Events (CTCAE) (weeks 1, 6 and 12). Pharmacist will assess for causality and severity in semistructured interviews using the CTCAE and Liverpool Causality Assessment Tool. The primary outcome is a reduction in ADRs among patients with actionable PGx variants, where an ADR will be considered as any CTCAE grade 2 and above for non-haematological toxicities and any CTCAE grade 3 and above for haematological toxicities Cost-effectiveness of pre-emptive PGx (secondary outcome) will be compared with standard of care using hospital inpatient and outpatient data along with the validated Childhood Health Utility 9D Instrument. Power and statistics considerations: A sample size of 440 patients (220 per arm) will provide 80% power to detect a 24% relative risk reduction in the primary endpoint of ADRs (two-sided α=5%, 80% vs 61%), allowing for 10% drop-out.Ethics and dissemination The ethics approval of the trial has been obtained from the Royal Children’s Hospital Ethics Committee (HREC/89083/RCHM-2022). The ethics committee of each participating centres nationally has undertaken an assessment of the protocol and governance submission.Trial registration number NCT05667766.

Abstract Pharmacogenomics remains underutilized in clinical practice, despite the existence of internationally recognized, evidence‐based guidelines. This systematic review aims to understand enablers and barriers to pharmacogenomics implementation in pediatric oncology by assessing the knowledge, attitudes, and practice of healthcare professionals and consumers. Medline, Embase, Emcare, and PsycINFO database searches identified 146 relevant studies of which only three met the inclusion criteria. These studies reveal that consumers were concerned with pharmacogenomic test costs, insurance discrimination, data sharing, and privacy. Healthcare professionals possessed mostly positive attitudes toward pharmacogenomic testing yet identified lack of experience and training as barriers to implementation. Education emerged as the key enabler, reported in all three studies and both healthcare professionals and consumer groups. However, despite the need for education, no studies utilizing a pediatric oncology consumer or healthcare professional group have reported on the implementation or analysis of a pharmacogenomic education program in pediatric oncology. Increased access to guidelines, expert collaborations and additional guidance interpreting results were further enablers established by healthcare professionals. The themes identified mirror those reported in broader pediatric genetic testing literature. As only a small number of studies met inclusion criteria for this review, further research is warranted to elicit implementation determinants and advance pediatric pharmacogenomics.

Abstract Background Pediatric acute lymphoblastic leukemia (ALL) therapy is accompanied by treatment-related toxicities (TRTs) and impaired quality of life. In Australia and New Zealand, children with ALL are treated with either Children’s Oncology Group (COG) or international Berlin-Frankfurt-Munster (iBFM) Study Group-based therapy. We conducted a prospective registry study to document symptomatic TRTs (venous thrombosis, neurotoxicity, pancreatitis and bone toxicity), compare TRT outcomes to retrospective TRT data, and measure the impact of TRTs on children’s general and cancer-related health-related quality of life (HRQoL) and parents’ emotional well-being. Methods Parents of children with newly diagnosed ALL were invited to participate in the ASSET (Acute Lymphoblastic Leukaemia Subtypes and Side Effects from Treatment) study and a prospective, longitudinal HRQoL study. TRTs were reported prospectively and families completed questionnaires for general (Healthy Utility Index Mark 3) and cancer specific (Pediatric Quality of Life Inventory (PedsQL)-Cancer Module) health related quality of life as well the Emotion Thermometer to assess emotional well-being. Results Beginning in 2016, 260 pediatric patients with ALL were enrolled on the TRT registry with a median age at diagnosis of 59 months (range 1–213 months), 144 males (55.4%), majority with Pre-B cell immunophenotype, n = 226 (86.9%), 173 patients (66.5%) treated according to COG platform with relatively equal distribution across risk classification sub-groups. From 2018, 79 families participated in the HRQoL study through the first year of treatment. There were 74 TRT recorded, reflecting a 28.5% risk of developing a TRT. Individual TRT incidence was consistent with previous studies, being 7.7% for symptomatic VTE, 11.9% neurotoxicity, 5.4% bone toxicity and 5.0% pancreatitis. Children’s HRQoL was significantly lower than population norms throughout the first year of treatment. An improvement in general HRQoL, measured by the HUI3, contrasted with the lack of improvement in cancer-related HRQoL measured by the PedsQL Cancer Module over the first 12 months. There were no persisting differences in the HRQoL impact of COG compared to iBFM therapy. Conclusions It is feasible to prospectively monitor TRT incidence and longitudinal HRQoL impacts during ALL therapy. Early phases of ALL therapy, regardless of treatment platform, result in prolonged reductions in cancer-related HRQoL.

Overall survival after cancer is increasing for the majority of cancer types, but survivors can be burdened lifelong by treatment-related severe toxicities. Integration of long-term toxicities in treatment evaluation is not least important for children and young adults with cancers with high survival probability. We present modified consensus definitions of 21 previously published physician-defined Severe Toxicities (STs), each reflecting the most serious long-term treatment-related toxicities and representing an unacceptable price for cure. Applying the Severe Toxicity (ST) concept to real-world data required careful adjustments of the original consensus definitions, translating them into standardized endpoints for evaluating treatment-related outcomes to ensure that (1) the STs can be classified uniformly and prospectively across different cohorts, and (2) the ST definitions allow for valid statistical analyses. The current paper presents the resulting modified consensus definitions of the 21 STs proposed to be included in outcome reporting of cancer treatment.

BackgroundIncreasing participation in physical activity has the potential to improve outcomes for children and adolescents with cancer during treatment and into survivorship. The aim of this study is to outline the theoretical process behind development of CanMOVE, a behavior change intervention designed to increase physical activity for children and adolescents with cancer.Study designThis study followed a theoretical design process consistent with the Behavior Change Wheel to inform the design of a complex intervention.Materials and methodsThe three stages of the Behavior Change Wheel intervention design process include: (1) understanding physical activity behavior within the pediatric cancer setting, (2) identifying potential intervention functions, and (3) identifying appropriate behavior change and implementation strategies. Qualitative and behavior change literature relevant to the pediatric cancer treatment setting were used to inform each stage.ResultsAn individualized and flexible approach to physical activity promotion that considers intrinsic factors specific to the child/adolescent and their environment is required. Fifteen behavioral change strategies were identified to form the intervention components of CanMOVE. Implementation strategies were identified to build motivation, opportunity and capacity toward increasing physical activity behaviors. Key intervention components of CanMOVE include standardized assessment and monitoring (physical activity, physical function, and health-related quality of life), provision of an activity monitor to both child/adolescent and parent, and one-on-one capacity building sessions with a healthcare professional. Capacity building sessions include education, goal setting, an active supervised physical activity session, barrier identification and problem solving, and action planning.ConclusionCanMOVE is a novel approach to physical activity promotion in the pediatric cancer treatment setting. The use of a theoretical intervention design process will aid evaluation and replication of CanMOVE when it is assessed for feasibility in a clinical setting. The design process utilized here can be used as a guide for future intervention development.

Abstract Background Pediatric cancer survivors are at increased risk of cardiac dysfunction and heart failure. Reduced peak oxygen consumption (peak VO2) is associated with impaired cardiac reserve (defined as the increase in cardiac function from rest to peak exercise) and heart failure risk, but it is unclear whether this relationship exists in pediatric cancer survivors. This study sought to investigate the presence of reduced peak VO2 in pediatric cancer survivors with increased risk of heart failure, and to assess its relationship with resting cardiac function and cardiac haemodynamics and systolic function during exercise. Methods Twenty pediatric cancer survivors (8–24 years; 10 male) treated with anthracycline chemotherapy ± radiation underwent cardiopulmonary exercise testing to quantify peak VO2, with a value

Abstract Background Anthracyclines are a mainstay of chemotherapy. However, a relatively frequent adverse outcome of anthracycline treatment is cardiomyopathy. Multiple genetic studies have begun to dissect the complex genetics underlying cardiac sensitivity to the anthracycline drug class. A number of single nucleotide polymorphisms (SNPs) have been identified to be in linkage disequilibrium with anthracycline induced cardiotoxicity in paediatric populations. Methods Here we screened for the presence of SNPs resulting in a missense coding change in a cohort of children with early onset chemotherapy related cardiomyopathy. The SNP identity was evaluated by Sanger sequencing of PCR amplicons from genomic DNA of patients with anthracycline related cardiac dysfunction. Results All of the published SNPs were observed within our patient group. There was no correlation between the number of missense variants an individual carried with severity of disease. Furthermore, the time to cardiac disease onset post-treatment was not greater in those individuals carrying a high load of SNPs resulting from missense variants. Conclusions We conclude that previously identified missense SNPs are present within a paediatric cohort with early onset heart damage induced by anthracyclines. However, these SNPs require further replication cohorts and functional validation before being deployed to assess anthracycline cardiotoxicity risk in the clinic.

Lower airway sampling is important in the assessment of lower respiratory tract infection in children with cancer or posthematopoietic stem cell transplant and can be done via bronchoalveolar lavage (BAL). Clinicians can struggle with balancing the benefits of BAL against the risks. This study aimed to define the diagnostic and clinical utility of BAL in this population.A single-center retrospective review of BAL performed in children with cancer or posthematopoietic stem cell transplant. Data extracted included demographics, BAL method and results and antimicrobial treatment. Variables significantly associated with diagnostic yield, diagnostic impact (confirmation or exclusion of infection), and clinical impact (any change in antimicrobial or nonantimicrobial therapy) were assessed in both univariate and multivariate analysis.Seventy-three BAL episodes were included. In 26 (35.6%) episodes, a pathogen was identified on BAL. Forty-nine (67%) BAL episodes had a diagnostic impact and 15 (21%) had a clinical impact. Late BAL (gt;72 hours) compared with early BAL (odds ratio 3.27; 95% CI: 1.03-10.86), and flexible bronchoscopy compared with nonbronchoscopic lavage (odds ratio 6.10; 95% CI: 1.90-24.0), were more likely to have a diagnostic impact on multivariate analysis. No associations were found for clinical impact.One-third of BAL episodes identified a pathogen, two-thirds had a diagnostic impact, and almost a quarter of episodes impacted antimicrobial prescribing. The method and timing of BAL may be important, with flexible bronchoscopy 6-fold more likely and late BAL 3-fold more likely to have a diagnostic impact.

Fever and infection are an important complication of childhood cancer therapy. Most research and guideline development has focussed on febrile neutropenia, with a paucity directed at non-neutropenic fever (NNF). We describe the clinical presentation, management and outcomes of NNF in children with cancer, and externally validate the Esbenshade Vanderbilt (EsVan) clinical decision rules (CDR) to predict bacteraemia.Using a prospective database, retrospective data were collected on consecutive NNF episodes (fever ≥38.0°C and absolute neutrophil count1.0 cells/mmThere were 203 NNF episodes occurring in 125 patients. Severe sepsis was uncommon (n = 2, 1%) and bacteraemia occurred in 10 (4.9%, 95% confidence interval [CI]: 2.7%-8.8%) episodes. A confirmed or presumed bacterial infection requiring antibiotics occurred in 31 (15%) patients. Total 202 (99%) episodes received at least one dose of intravenous broad-spectrum antibiotic and 141 (70%) episodes were admitted to hospital. Six (3%) episodes required intensive care unit (ICU)-level care and there were no infection-related deaths. The EsVan 1 rule had an AUC-ROC of 0.67, 80% were identified as low risk, and sensitivity and specificity were 50% and 81.5%, respectively, for a risk threshold of 10%.Serious infection and adverse outcome are uncommon in children with NNF. Many children did not have a bacterial cause of infection identified, but were still treated with broad-spectrum antibiotics and admitted to hospital. National clinical practice guidelines should be developed for this important cohort to enable risk stratification and optimise antibiotic management. Further research is required to determine appropriateness of EsVan CDR in our cohort.

Purpose: While central nervous system (CNS) tumors account for only 10% of adolescent and young adult (AYA) cancers, they are the leading cause of cancer death in this age group. Using national data for Australia, we describe the presentation, treatment, and survival for AYAs diagnosed with CNS tumors. Methods: A population-based study of 15-24 year-olds diagnosed with CNS tumors (low- and high-grade glioma [LGG, HGG], medulloblastoma [MB], primitive neuroectodermal tumors [PNET], ependymoma [EP]) or other (e.g., low-grade neuronal tumor) between 2007 and 2012. Clinical details were extracted from hospital medical records for each patient. Treatment centers were classified as pediatric or adult services. Results: Two hundred seventy-five patients (129 LGG, 77 HGG, 23 MB, 10 PNET, 19 EP, 17 other) were identified, with 17% treated at pediatric hospitals. Symptoms (headache [53%], nausea [31%]) were present for a median of 3 weeks before consulting a health professional. Of LGG patients, 15% had radiotherapy (RT) and 12% chemotherapy (CT). Of HGG patients, 81% had RT and 75% CT. All MB and PNET were managed with surgery, and 74% of MB and 80% of PNET had both RT and CT. Treatment did not differ by treatment center type. Five-year survival for LGG and EP was over 80%, but was 42% for HGG and 20% for PNET. Conclusions: This national, population-based study indicates similar treatment for AYA patients with CNS tumors between pediatric and adult services. Poor outcomes for HGG and PNET patients highlight the need for clinical trials of novel approaches for these tumors Refereed/Peer-reviewed

Cancer therapy related cardiac dysfunction (CTRCD) is an area of increasing focus, particularly during the survivorship period, for paediatric, adolescent and adult cancer survivors. With the advent of immunotherapy and targeted therapy, there is a new set of mechanisms from which paediatric and young adult patients with cancer may suffer cardiovascular injury. Furthermore, cardiovascular disease is the leading cause of morbidity and mortality in the survivorship period. The recently established Australian Cardio-Oncology Registry is the largest and only population-based cardiotoxicity database of paediatric and adolescent and young adult oncology patients in the world, and the first paediatric registry that will document cardiotoxicity caused by chemotherapy and novel targeted therapies using a prospective approach. The database is designed for comprehensive data collection and evaluation of the Australian practice in terms of diagnosis and management of CTRCD. Using the Australian Cardio-Oncology Registry critical clinical information will be collected regarding predisposing factors for the development of CTRCD, the rate of subclinical left ventricular dysfunction and transition to overt heart failure, further research into protectant molecules against cardiac dysfunction and aid in the discovery of which genetic variants predispose to CTRCD. A health economic arm of the study will assess the cost/benefit of both the registry and cardio-oncology clinical implementation. Finally, an imaging arm will establish if exercise cardiac magnetic resonance imaging and VO2 max testing is a more sensitive predictor of cardiac reserve in paediatric and adolescent and young adult oncology patients exposed to cardiac toxic therapies.

- Abstract
Patients post haematopoietic stem cell transplant or CAR-T cell therapy face significant risk of morbidity and mortality from SARS-CoV19, due to 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 learnt 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 optimally manage our patients.

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. We also recommend prioritising vaccination of TCT healthcare workers and household members of TCT patients. Vaccination should not replace other public health measures in TCT patients given the effectiveness of COVID‐19 vaccination in TCT patients is unknown. Furthermore, given the limited available data, prospective collection of safety and efficacy data of COVID‐19 vaccination in this patient group is a priority.

INTRODUCTION: A pandemic coronavirus, SARS-CoV-2, causes COVID-19, a potentially life-threatening respiratory disease. Patients with cancer may have compromised immunity due to their malignancy and/or treatment, and may be at elevated risk of severe COVID-19. Community transmission of COVID-19 could overwhelm health care services, compromising delivery of cancer care. This interim consensus guidance provides advice for clinicians managing patients with cancer during the pandemic. MAIN RECOMMENDATIONS: During the COVID-19 pandemic: In patients with cancer with fever and/or respiratory symptoms, consider causes in addition to COVID-19, including other infections and therapy-related pneumonitis. For suspected or confirmed COVID-19, discuss temporary cessation of cancer therapy with a relevant specialist. Provide information on COVID-19 for patients and carers. Adopt measures within cancer centres to reduce risk of nosocomial SARS-CoV-2 acquisition; support population-wide social distancing; reduce demand on acute services; ensure adequate staffing; and provide culturally safe care. Measures should be equitable, transparent and proportionate to the COVID-19 threat. Consider the risks and benefits of modifying cancer therapies due to COVID-19. Communicate treatment modifications, and review once health service capacity allows. Consider potential impacts of COVID-19 on the blood supply and availability of stem cell donors. Discuss and document goals of care, and involve palliative care services in contingency planning. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: This interim consensus guidance provides a framework for clinicians managing patients with cancer during the COVID-19 pandemic. In view of the rapidly changing situation, clinicians must also monitor national, state, local and institutional policies, which will take precedence.

Background Anthracyclines are a mainstay of chemotherapy. However, a relatively frequent adverse outcome of anthracycline treatment is cardiomyopathy. Multiple genetic studies have begun to dissect the complex genetics underlying cardiac sensitivity to the anthracycline drug class. A number of single nucleotide polymorphisms (SNPs) have been identified to be in linkage disequilibrium with anthracycline induced cardiotoxicity in paediatric populations. Methods Here we screened for the presence of SNPs resulting in a missense coding change in a cohort of children with early onset chemotherapy related cardiomyopathy. The SNP identity was evaluated by Sanger sequencing of PCR amplicons from genomic DNA of patients with anthracycline related cardiac dysfunction. Results All of the published SNPs were observed within our patient group. There was no correlation between the number of missense variants an individual carried with severity of disease. Furthermore, the time to cardiac disease onset post-treatment was not greater in those individuals carrying a high load of SNPs resulting from missense variants. Conclusions We conclude that previously identified missense SNPs are present within a paediatric cohort with early onset heart damage induced by anthracyclines. However, these SNPs require further replication cohorts and functional validation before being deployed to assess anthracycline cardiotoxicity risk in the clinic.

To assess the impact of a pilot nurse-led paediatric oncology fast-track clinic (OFTC) for complications and side effects following chemotherapy within a paediatric tertiary hospital. Prospective clinical data from the first 100 patients seen in the OFTC were compared with retrospective data of oncology patient presentations to the emergency department (ED) (over a 1-year period, n = 196) who would have been eligible for review in the OFTC. Parent and patient satisfaction of clinical care were also assessed via surveys pre- and post-OFTC implementation. Analysis which achieved statistical difference was a reduction in the number of blood tubes taken in OFTC (average 1.9 for those discharged from clinic, 2.9 for those admitted from clinic) in comparison to those seen in the ED (average 3.2) (p = 0.0027). The average number of interventions per patient seen in the ED were 2.1 (standard deviation 1.64) compared with 1.7 (standard deviation 1.55) interventions per patient seen in the OFTC, and who were not admitted following review. This result approached statistical significance with p = 0.0963. Other results which did not meet statistical significance included a reduction in treatment times, hospital admissions and medical oncology reviews. Our pilot study implementing an OFTC for the triage and assessment of chemotherapy-related complications has proven successful from an operational and consumer perspective. The clinic improved care by ensuring expedited review, more streamlined interventions, and less overall hospital admissions. The improvements in efficiency were also mirrored by increased parent and patient satisfaction.

The Australian Technical Advisory Group on Immunisation and New Zealand Ministry of Health recommend all children aged ≥ 5 years receive either of the two mRNA COVID-19 vaccines: Comirnaty (Pfizer), available in both Australia and New Zealand, or Spikevax (Moderna), available in Australia only. Both vaccines are efficacious and safe in the general population, including children. Children and adolescents undergoing treatment for cancer and immunosuppressive therapy for non-malignant haematological conditions are particularly vulnerable, with an increased risk of severe or fatal COVID-19. There remains a paucity of data regarding the immune response to COVID-19 vaccines in immunosuppressed paediatric populations, with data suggestive of reduced immunogenicity of the vaccine in immunocompromised adults.Considering the safety profile of mRNA COVID-19 vaccines and the increased risk of severe COVID-19 in immunocompromised children and adolescents, COVID-19 vaccination is strongly recommended for this at-risk population. We provide a number of recommendations regarding COVID-19 vaccination in this population where immunosuppressive, chemotherapeutic and/or targeted biological agents are used. These include the timing of vaccination in patients undergoing active treatment, management of specific situations where vaccination is contraindicated or recommended under special precautions, and additional vaccination recommendations for severely immunocompromised patients. Finally, we stress the importance of upcoming clinical trials to identify the safest and most efficacious vaccination regimen for this population.This consensus statement provides recommendations for COVID-19 vaccination in children and adolescents aged ≥ 5 years with cancer and immunocompromising non-malignant haematological conditions, based on evidence, national and international guidelines and expert opinion.The Australian and New Zealand Children's Haematology/Oncology Group.

Background: While overall survival (OS) for cancer in adolescents and young adults (AYA) has improved, there has been little change in AYA survival for several types of sarcomas. Using national data for Australia we describe (1) the treatment centers caring for AYA sarcoma, (2) treatments provided, and (3) survival outcomes. Procedure: National population-based study assessing treatment of 15-24 year-olds diagnosed with soft tissue sarcoma (STS), bone sarcoma (BS), and Ewing family tumors (ET) between 2007 and 2012. Treatment details were abstracted from hospital medical records. Treatment centers were classified as pediatric or adult specialist AYA/sarcoma center, or other adult. Cox proportional hazard regression analyses examined associations between type of treatment center and OS. Results: Sixty-one hospitals delivered treatment to 318 patients (135 STS; 91 BS, 92 ET), with 9%, 22%, and 17% of STS, BS, and ET, respectively, treated at pediatric and 62%, 59%, and 71% at adult specialist hospitals. Of 18-24 year-olds, 82% of BS, 90% of ET, and 73% of rhabdomyosarcomas at adult specialist centers were on a trial or standard protocol, compared with 42%, 89%, and 100%, respectively, at nonspecialist adult hospitals. After adjusting for disease and patient characteristics, survival was not associated with treatment center type for any disease type. However, ET survival was poorer for patients not receiving a standard chemotherapy protocol. Conclusions: Around 10% of AYA sarcoma patients attending adult hospitals were not on a standard protocol. Poorer survival for ET patients not on a standard protocol highlights the importance of ensuring all patients receive optimal care. usc Refereed/Peer-reviewed

5-year overall survival rates have surpassed 90% for childhood acute lymphocytic leukaemia, but survivors are at risk for permanent health sequelae. Although event-free survival appropriately represents the outcome for cancers with poor overall survival, this metric is inadequate when cure rates are high but challenged by serious, persistent complications. Accordingly, a group of experts in paediatric haematology-oncology, representative of 17 international acute lymphocytic leukaemia study groups, launched an initiative to construct a measure, designated severe toxicity-free survival (STFS), to quantify the occurrence of physician-prioritised toxicities to be integrated with standard cancer outcome reporting. Five generic inclusion criteria (not present before cancer diagnosis, symptomatic, objectifiable, of unacceptable severity, permanent, or requiring unacceptable treatments) were used to assess 855 health conditions, which resulted in inclusion of 21 severe toxicities. Consensus definitions were reached through a modified Delphi process supplemented by two additional plenary meetings. The 21 severe toxicities include severe adverse health conditions that substantially affect activities of daily living and are refractory to therapy (eg, refractory seizures), are without therapeutic options (eg, blindness), or require substantially invasive treatment (eg, cardiac transplantation). Incorporation of STFS assessment into clinical trials has the potential to improve and diversify treatment strategies, focusing not only on traditional outcome events and overall survival but also the frequencies of the most severe toxicities. The two major aims of this Review were to: prioritise and define unacceptable long-term toxicity for patients with childhood acute lymphocytic leukaemia, and define how these toxicities should be combined into a composite quantity to be integrated with other reported outcomes. Although STFS quantifies the clinically unacceptable health tradeoff for cure using childhood acute lymphocytic leukaemia as a model disease, the prioritised severe toxicities are based on generic considerations of relevance to any other cancer diagnosis and age group.

Background Young cancer survivors are at increased risk of impaired cardiopulmonary fitness (VO2peak) and heart failure. Assessment of exercise cardiac reserve may reveal sub-clinical abnormalities that better explain impairments in fitness and long term heart failure risk. Purpose To investigate the presence of impaired VO2peak in pediatric cancer survivors with increased risk of heart failure, and to assess its relationship with resting cardiac function and cardiac reserve Methods Twenty pediatric cancer survivors (aged 8–24 years) treated with anthracycline chemotherapy underwent cardiopulmonary exercise testing to quantify VO2peak, with a value Results 12 of 20 survivors (60%) had impaired VO2peak (97±14% vs. 70±16% of age and gender predicted). There were no differences in echocardiographic or CMR measurements of resting cardiac function between survivors with normal or impaired VO2peak. However, those with reduced VO2peak had diminished cardiac reserve, with a lesser increase in CI (Fig. 1A) and SVi (Fig. 1B) during exercise (Interaction P=0.001 for both), whilst the HR response was similar (Fig. 1C; P=0.71). Conclusions Resting measures of cardiac function are insensitive to significant cardiac dysfunction amongst pediatric cancer survivors with reduced VO2peak. Measures of cardiopulmonary fitness and cardiac reserve may aid in early identification of survivors with heightened risk of long-term heart failure.

Background Pediatric cancer survivors are at increased risk of cardiac dysfunction and heart failure. Reduced peak oxygen consumption (peak VO2) is associated with impaired cardiac reserve (defined as the increase in cardiac function from rest to peak exercise) and heart failure risk, but it is unclear whether this relationship exists in pediatric cancer survivors. This study sought to investigate the presence of reduced peak VO2 in pediatric cancer survivors with increased risk of heart failure, and to assess its relationship with resting cardiac function and cardiac haemodynamics and systolic function during exercise. Methods Twenty pediatric cancer survivors (8–24 years; 10 male) treated with anthracycline chemotherapy ± radiation underwent cardiopulmonary exercise testing to quantify peak VO2, with a value 2. Resting cardiac function was assessed using 2- and 3-dimensional echocardiography, with cardiac reserve quantified from resting and peak exercise heart rate, stroke volume index (SVI) and cardiac index (CI) using exercise cardiovascular magnetic resonance (CMR). Results Twelve of 20 survivors (60%) had reduced peak VO2 (70 ± 16% vs. 97 ± 14% of age and gender predicted). There were no differences in echocardiographic or CMR measurements of resting cardiac function between survivors with normal or impaired peak VO2. However, those with reduced peak VO2 had diminished cardiac reserve, with a lesser increase in CI and SVI during exercise (Interaction P P = 0.71). Conclusions Whilst exercise intolerance is common among pediatric cancer survivors, it is poorly explained by resting measures of cardiac function. In contrast, impaired exercise capacity is associated with impaired haemodynamics and systolic functional reserve measured during exercise. Consequently, measures of cardiopulmonary fitness and cardiac reserve may aid in early identification of survivors with heightened risk of long-term heart failure.

Introduction Sub-cutaneous panniculitis T-cell lymphomas (SPTCL), a rare non-Hodgkin lymphoma, can be associated with hemophagocytic lymphohistiocytosis (HLH), a life-threatening activation of the immune system which adversely impacts survival. T-cell immunoglobulin mucin 3 (TIM-3) is a modulator of immune responses expressed on subgroups of T- and innate immune cells. In this work we describe the first germline variants associated with SPTCL, which are in the TIM-3 gene. Methods We sequenced 27 SPTCL cases to identify gene variants. We performed TIM-3 functional analysis on immune cells from patients and HEK293 cells engineered to overexpress wild-type or mutant TIM-3. Results We identified homozygous, germline, loss-of-function, missense variants in highly conserved residues of TIM-3, namely p.Y82C and p.I97M in about 60% (16/27) of SPTCL cases. These samples were drawn from cases series across 3 continents. Patients with bi-allelic TIM-3 mutations were younger at diagnosis, and several had life-threatening HLH and severe disease course. TIM-3 mutations show specific geographic distribution. Y82C TIM-3 mutations occur on a founder chromosome in patients with East-Asian and Polynesian ancestry, while I97M TIM-3 is observed in Caucasians. Both variants induce protein misfolding and cytoplasmic retention of TIM-3. Loss of TIM-3 membrane expression in TIM-3 mutants abrogates the PD-1/PDL-1 checkpoint and prevents the termination of a Th1-immune response. In HEK293 cells, mutant TIM-3 was not expressed on the cell surface. Defective TIM-3 expression leads to persistent immune activation with increased production of inflammatory cytokines including TNF-alpha and IL-1beta by innate immune cells. Conclusion Our findings highlight HLH/SPTCL as a new genetic entity where loss of the TIM-3 immune checkpoint is associated with T-cell infiltration of adipose tissue and inflammasome activation. This is the first causative germline defect identified in SPTCL. While our findings indicate that TIM-3-mutant HLH/SPTCL benefit from immunomodulation, therapeutic repression of the TIM-3 checkpoint could have serious adverse consequences.

Purpose: This study investigated the impact of fertility-related discussions on Adolescent and Young Adult (AYA) cancer patients' quality of life (QoL) and the factors influencing provision of these discussions. Methods: Recruitment was conducted through population-based state cancer registries. Eligible AYAs were 15-24 years at diagnosis, 3-24 months postdiagnosis, with any cancer (except early stage melanoma). As part of a larger survey, AYAs were asked about their experiences of fertility-related discussions and QoL (FACT-G). Results: Of the 207 AYAs returning surveys (29% response rate) 88% reported a discussion about infertility risks, 75% reported a discussion about preservation options and 59% were offered a referral to a fertility specialist. Patients attending health services with an AYA focus were more likely than those attending other types of centers to report discussions of fertility preservation (FP) options (85% versus 67%) and referrals (75% versus 49%). Social well-being was positively related to discussions about preservation options and being provided fertility risk information in a sensitive, supportive manner. Conclusions: Providing a sensitive and proactive discussion about fertility-related risks may benefit AYAs' well-being. Services with an AYA focus are fulfilling their mandate of ensuring optimal fertility-related care for AYA cancer patients usc Refereed/Peer-reviewed

Sarcomas are a group of heterogeneous tumours with varying genetic basis. Cytogenetic abnormalities range from distinct genomic rearrangements such as pathognomonic translocation events and common chromosomal amplification or loss, to more complex rearrangements involving multiple chromosomes. The different subtypes of liposarcoma are spread across this spectrum and constitute an interesting tumour type for molecular review. This paper will outline molecular pathogenesis of the three main subtypes of liposarcoma: well-differentiated/dedifferentiated, myxoid/round cell, and pleomorphic liposarcoma. Both the molecular basis and future avenues for therapeutic intervention will be discussed.

Background It has long been established that cardiotoxicity occurs as a result of exposure to certain chemotherapeutics, particularly anthracyclines. Historically, clinicians equate cardiotoxicity with a poor prognosis, in a small percentage of patients and deem long-term surveillance as optional. Emerging evidence suggests that anthracycline cardiotoxicity (ACT) is a life-long risk with an incidence approaching 20%. Aims To elucidate the incidence of anthracycline cardiotoxicity within a current paediatric oncology survivor cohort. Methods Participants were identified through the Haematology-Oncology database at the Royal Children's Hospital, Melbourne. Patients were identified from a retrospective audit of outpatient attendances between January 2008 and December 2015. Patients with a cancer diagnosis exposed to anthracyclines were eligible for the study. Patient demographics and echocardiogram findings were recorded with patients subcategorised according to degree of ACT. More significant ACT defined as fractional shortening (FS) 10%. Results Two hundred and eighty-six of a total 481 identified patients were eligible for study inclusion. Twenty patients displayed significant ACT with FS 10%. Overall, 6.6% demonstrated significant cardiac complications, whilst 19.6 % demonstrated some degree of ACT and decline in myocardial function. When stratified for cumulative anthracycline dose, the incidence of severe cardiac dysfunction was 5.1% ( 250 mg/m2) Conclusion This study demonstrates, in keeping with modern literature, the higher incidence of anthracycline associated cardiac toxicity and a need for better surveillance and follow up.

Background Little is known about how to facilitate participation in physical activity among children receiving acute cancer treatment. Objective To understand the parental perspectives on physical activity for children during acute cancer treatment and explore strategies to overcome physical inactivity. Methods A qualitative study was completed. Data were collected via semistructured interviews with parents of children (aged 4-18 years) who were in their first nine months of cancer treatment. Data were analyzed thematically. Results Twenty parents were interviewed. A childhood cancer diagnosis and subsequent treatment were described as setting in motion a spiral of physical inactivity. Parents identified movement restrictions as a result of commencing treatment and the hospital environment as factors initiating this decline. Parents described the subsequent impact of movement restrictions on their child over time including loss of independence, isolation, and low motivation. These three consequences further contributed to an inability and unwillingness to be physically active. Parents responded in a variety of ways to their child's inactivity, and many were motivated to overcome the barriers to physical activity yet exhibited a reduced capacity to do so. Suggested intervention strategies highlighted the need for comprehensive support from the organization providing treatment. Conclusions Reasons for reduced physical activity in children receiving acute treatment for cancer are complex and multifactorial. Inactivity cannot be addressed by children and parents alone but requires support from the oncology team through changes to the environment, services, and policies to promote physical activity. These findings may be used to inform targeted, effective, and feasible physical activity interventions.

Subcutaneous panniculitis-like T cell lymphoma (SPTCL), a non-Hodgkin lymphoma, can be associated with hemophagocytic lymphohistiocytosis (HLH), a life-threatening immune activation that adversely affects survival1,2. T cell immunoglobulin mucin 3 (TIM-3) is a modulator of immune responses expressed on subgroups of T and innate immune cells. We identify in ~60% of SPTCL cases germline, loss-of-function, missense variants altering highly conserved residues of TIM-3, c.245A>G (p.Tyr82Cys) and c.291A>G (p.Ile97Met), each with specific geographic distribution. The variant encoding p.Tyr82Cys TIM-3 occurs on a potential founder chromosome in patients with East Asian and Polynesian ancestry, while p.Ile97Met TIM-3 occurs in patients with European ancestry. Both variants induce protein misfolding and abrogate TIM-3’s plasma membrane expression, leading to persistent immune activation and increased production of inflammatory cytokines, including tumor necrosis factor-α and interleukin-1β, promoting HLH and SPTCL. Our findings highlight HLH–SPTCL as a new genetic entity and identify mutations causing TIM-3 alterations as a causative genetic defect in SPTCL. While HLH–SPTCL patients with mutant TIM-3 benefit from immunomodulation, therapeutic repression of the TIM-3 checkpoint may have adverse consequences.

Background/Aim The aim of this study was to describe the time and documentation needed to gain ethics and governance approvals in Australian states with and without a centralised ethical review system. Methods This is a prospective descriptive study undertaken between February 2012 and March 2015. Paediatric and adult hospitals (n = 67) in Australian states were approached to allow the review of their medical records. Participants included 15- to 24-year-olds diagnosed with cancer between 2008 and 2012. The main outcomes measures were time (weeks) to approval for ethics and governance and the number and type of documents submitted. Results Centralised ethics approval processes were used in five states, with approval taking between 2 and 18 weeks. One state did not use a centralised process, with ethics approval taking a median of 4.5 weeks (range: 0–15) per site. In four states using a centralised ethics process, 33 governance applications were submitted, with 20 requiring a site clinician listed as an investigator. Governance applications required the submission of 11 documents on average, including a Site-Specific Assessment form. Thirty-two governance applications required original signatures from a median of 3.5 (range: 1–10) non-research persons, which took a median of 5 weeks (range: 0–15) to obtain. Governance approval took a median of 6 weeks (range: 1–45). Twelve research study agreements were needed, each taking a median of 7.5 weeks (range: 1–20) to finalise. Conclusion The benefits of centralised ethics review systems have not been realised due to duplicative, inflexible governance processes. A system that allowed the recognition of prior ethical approval and low-risk applications was more efficient than a central ethics and site-specific governance process.

Anthracycline-induced cardiotoxicity (ACT) is a severe adverse drug reaction for a subset of children treated with anthracyclines as part of chemotherapy protocols. The identification of genetic markers associated with increased ACT susceptibility has clinical significance toward improving patient care and our understanding of the molecular mechanisms involved in ACT. Human-induced pluripotent stem cell-derived cardiomyocytes represent a novel approach to determine the pharmacogenomics of ACT and guide the development of genetic screening tests.

Background: While several studies have examined the treatment of adolescents and young adults (AYAs) with acute lymphoblastic leukemia (ALL), studies of acute myeloid leukemia (AML) are rare. Using national data for Australia, we describe (i) the number and type of treatment centers caring for AYAs, (ii) induction/first-line treatments, and (iii) survival outcomes. Procedure: National population-based study assessing treatment of 15- to 24-year-olds diagnosed with ALL or AML between 2007 and 2012. Treatment details were abstracted from hospital medical records. Treatment centers were classified as pediatric or adult (adult AYA-focused or other adult; and by AYA volume [high/low]). Cox proportional hazard regression analyses examined associations between treatment and overall, event-free, and relapse-free survival outcomes. Results: Forty-seven hospitals delivered induction therapy to 351 patients (181 ALL and 170 AML), with 74 (21%) treated at pediatric centers; 70% of hospitals treated less than two AYA leukemia patients per year. Regardless of treatment center, 82% of ALL patients were on pediatric protocols. For AML, pediatric protocols were not used in adult centers, with adult centers using a non-COG 7+3-type induction protocol (51%, where COG is Cooperative Oncology Group) or an ICE-type protocol (39%, where ICE is idarubicin, cytarabine, etoposide). Exploratory analyses suggested that for both ALL and AML, AYAs selected for adult protocols have worse overall, event-free, and relapse-free survival outcomes. Conclusions: Pediatric protocols were commonly used for ALL patients regardless of where they are treated, indicating rapid assimilation of recent evidence by Australian hematologists. For AML, pediatric protocols were only used at pediatric centers. Further investigation is warranted to determine the optimal treatment approach for AYA AML patients. usc Refereed/Peer-reviewed

International data indicate that rates of clinical trial enrolment for Adolescents and Young Adults (AYAs) with cancer are markedly lower than for any other age group. This paper reviews the recent literature reporting international trends in clinical trial enrolment since 2010. Subsequently, we present the first population-based, national assessment of clinical trial enrolment for AYAs with cancer in Australia. Reported rates of trial enrolment from Australia, Canada, the United States, and the United Kingdom were variable, though consistently low, ranging between 2% and 29%. Trial enrolment was higher for younger AYAs (typically 15-19 years) and those attending pediatric hospitals, and this was replicated in the recent Australian data. The findings highlight a lack of substantial improvement in AYA clinical trial enrolment and in particular, a need for improved opportunities to access trials for patients treated at adult centers.

Purpose A cancer diagnosis and treatment may have significant implications for a young patient's future fertility. Documentation of fertility-related discussions and actions is crucial to providing the best follow-up care, which may occur for many years post-treatment. This study examined the rate of medical record documentation of fertility-related discussions and fertility preservation (FP) procedures for adolescents and young adults (AYAs) with cancer in Australia. Methods A retrospective review of medical records for 941 patients in all six Australian states. Patients were identified through population-based cancer registries (four states) and hospital admission lists (two states). Trained data collectors extracted information from medical records using a comprehensive data collection survey. Records were reviewed for AYA patients (aged 15–24 years at diagnosis), diagnosed with acute myeloid leukaemia, acute lymphoblastic leukaemia, central nervous system (CNS) tumours, soft tissue sarcomas (STS), primary bone cancer or Ewing's family tumours between 2007 and 2012. Results 47.2% of patients had a documented fertility discussion and 35.9% had a documented FP procedure. Fertility-related documentation was less likely for female patients, those with a CNS or STS diagnosis and those receiving high-risk treatments. In multivariable models, adult hospitals with an AYA focus were more likely to document fertility discussions (odds ratio[OR] = 1.60; 95%CI = 1.08–2.37) and FP procedures (OR = 1.74; 95%CI = 1.17–2.57) than adult hospitals with no AYA services. Conclusions These data provide the first national, population-based estimates of fertility documentation for AYA cancer patients in Australia. Documentation of fertility-related discussions was poor, with higher rates observed in hospitals with greater experience of treating AYA patients.

Many paediatric patients with cancer experience significant chemotherapy side effects. Predisposition to drug reactions is governed by single nucleotide polymorphisms (SNPs). We performed a systematic review of the literature from 2006 through 2016. Outcomes of interest included patient characteristics, cancer type drug of interest, genes investigated, toxicity identified and genetic polymorphisms implicated. The primary toxicities studied were neurotoxicity cardiotoxicity, osteonecrosis, and thromboembolism and hypersensitivity reactions. The retrieved studies were grouped according to toxicity reported and SNP associations. This review highlights the discoveries to date in pharmacogenomics and paediatric oncology along with highlighting some of the important limitations in the area.

Objective: To examine the relationship between the cancer care experiences of adolescents and young adults (AYAs) and their quality of life. Methods: Two hundred and nine AYAs completed a cross-sectional, self-report survey distributed through the population-based cancer registries in 2 Australian states (New South Wales and Victoria). Eligible AYAs were 15 to 24 years old when diagnosed with any cancer (excluding early-stage melanoma) and were 3 to 24 months post-diagnosis. Questions examined whether particular care experiences occurred for the patient at different points in the cancer care pathway, including diagnosis, treatment, inpatient care, and at the end of treatment. Quality of life was assessed using the Functional Assessment of Cancer Therapy-General scale. Results: Positive experiences of care at diagnosis, during treatment, during inpatient stays, and when finishing treatment were associated with higher functional, emotional, and social well-being. However, these associations generally became nonsignificant when communication and support experiences were included in the model. Inpatient experiences positively influenced emotional well-being over and above the effect of communication and support experiences. Conclusions: The results suggest that, for most AYAs' quality of life outcomes, positive experiences of age-appropriate communication and emotional support may underpin the effect of positive experiences of care throughout the cancer care pathway. The results support the need for communication and support tailored to an AYA audience, as recognised by recent Australian and international guidelines on the care of AYAs with cancer. usc Refereed/Peer-reviewed

Given the decades of survivorship for adolescent and young adult (AYA) cancer survivors, it is important to promote behaviours that enhance physical and mental well-being and quality of life (QoL). The purpose of this study was to explore the exercise programming preferences and information needs of AYA survivors and to examine the impact of a cancer diagnosis on physical activity behavior and QoL. Participants aged 15–25 years at time of diagnosis and referred to a specialist AYA cancer service between January 2008 and February 2012 were recruited. Eligible participants were mailed a self-administered questionnaire assessing demographic and disease-related information, physical activity levels over time and exercise information preferences. QoL was measured using the Assessment of Quality of Life-6D (AQoL-6D). Seventy-four (response rate 52 %) participants completed the questionnaire. The mean age was 23 years with 54 % female, with prevalent diagnoses included hematological malignancy (45 %) and sarcoma (24 %). Results indicated a significant reduction in the average minutes of physical activity post diagnosis (p =

Systemic anaplastic large cell lymphoma (ALCL) is a distinct disease classification provisionally sub-divided into ALCL, Anaplastic Lymphoma Kinase (ALK)+ and ALCL, ALK− entities. More recently, another category of ALCL has been increasingly reported in the literature and is associated with the presence of breast implants. A comprehensive review of the 71 reported cases of breast implant associated ALCL (iALCL) is presented indicating the apparent risk factors and main characteristics of this rare cancer. The average patient is 50 years of age and most cases present in the capsule surrounding the implant as part of the periprosthetic fluid or the capsule itself on average at 10 years post-surgery suggesting that iALCL is a late complication. The absolute risk is low ranging from 1:500,000 to 1:3,000,000 patients with breast implants per year. The majority of cases are ALK-negative, yet are associated with silicone-coated implants suggestive of the mechanism of tumorigenesis which is discussed in relation to chronic inflammation, immunogenicity of the implants and sub-clinical infection. In particular, capsulotomy alone seems to be sufficient for the treatment of many cases suggesting the implants provide the biological stimulus whereas others require further treatment including chemo- and radiotherapy although reported cases remain too low to recommend a therapeutic approach. However, CD30-based therapeutics might be a future option.
