PAEDIATRIC ONCOLOGY AND CLINICAL RESEARCH AT THE CHILDREN’S CANCER CENTRE MONASH CHILDREN’S (MMC) Dr. Peter Downie FRACP Head, CCC Monash Children’s Paediatric Cancer in Context There are approximately 200 children diagnosed with cancer in Victoria each year Approximately 45% - leukaemia + lymphoma 25% CNS tumours Likelihood of diagnosis of cancer from birth to adulthood 1:300 males/1:333 females More common in industrialised nations Incidence of Cancer in Children under 15 years in Selected areas of the World Fiji Indian India Fiji Fijian Israel Non-Jews Israel Jews USA Spain Australia Sweden New Zealand Brazil Nigeria 0 100 200 Rate/million Distribution of Cancers in Children under 15 years Leukaemia 35% Lymphoma 14% Neuroblastoma 9% Other 5% Liver 1% Retinoblastoma 3% Bone and STS 15% Wilms' 8% CNS 20% Health of Australian Children ABS data – approximately 4.5 million children aged under 15 years in Australia or 20% of the total population Health gains better living conditions education medical care and vaccination ~ would suggest that this generation of children should be the healthiest ever Emerging concerns related to rapid social change and associated new morbidities such as increasing levels of behavioural, developmental, mental health and social problems In 2006, 41% of children aged under 15 years had a long-term health condition compared with 44% in 2001(ABS 2006 & ABS 2002). Boys (44%) were more likely than girls (38%) to have a long term health condition. Respiratory diseases - 20% of children - the main conditions were asthma (12%), hayfever and allergic rhinitis (8%) and chronic sinusitis (3%) Mental and behavioural problems were reported for 7% of children overall - these main conditions were behavioural & emotional problems with usual onset in childhood or adolescence (3%) and problems of psychological development (3%) Australian Childhood mortality In a single year (2004) there were 569 deaths of children aged 1-14 years. The death rate for children was 15 per 100,000 children (ABS 2006c). Of the total deaths of children aged 1-14 years, 60% were male and 40% were female resulting in death rates of 18 per 100,000 boys and 13 per 100,000 girls. Australian Childhood mortality Assault accounted for 9% of childhood deaths between 1999 and 2003 (128 childhood deaths). Of these deaths, two thirds (65%) occurred for children aged under five years (ABS 2005a). The major causes of death in children were; external causes (36%) cancer (19%) diseases of the nervous system (11%) External causes of death among children – traffic accidents, accidents at home, accidental drowning.

A total of 319 children were enrolled on a clinical trial in 2010 (this represents 42% of the number of newly diagnosed children in 2010 [n=759]) Trials available per site ranged from 11-64, with an average of 30 trials per site 87/190 children (46%) whose records were reviewed across all sites, were eligible for a trial available at their ACCT service site 65 / 87 eligible children (75%) were enrolled in a clinical trial with the overall % of eligible children enrolled on a trial ranging from 25% - 100% per site (ranging from 1/4 eligible children to 9/9 eligible children per site) 47/65 enrolled children (72%) were children with leukaemia 19/87 eligible children, clinical trial participation was not discussed with their parents. Two sites being identified as ‘higher enrollers’, four sites as ‘moderate enrollers’ and two sites as ‘small sites’. What we learned…. Key Elements of a Best Practice Program Organisational culture and clinical leadership Clinical trial staffing resources and skills Good range of trials available on site Streamlined ethics and governance Optimal internal systems and processes Clinical trial review and quality improvement processes National and cross-site collaboration Key Elements of a Best Practice Program National and cross-site collaboration The need to improve outcomes for a gradually decreasing population of children for whom outcomes remain poor, often with rare tumours; as a result it is essential that an even stronger global, collaborative perspective be undertaken Increasing pharmaceutical costs and difficulties accessing drugs Clinical Trials Phase II testing of candidate agents is (still) the only way to identify activity of new drugs in “orphan” diseases. Molecular arrays - tell us how to match drugs with tumours ? process will become less empirical. E.g. Testing STI-571 (imatinib) in gliomas; drug is an inh of the bcr-abl kinase activated in CML ~ highly active; Also an effective inhibitor of related kinase PDGF-R, overexpressed in many gliomas. This - targeted therapy great appeal; but no substitute for doing comprehensive trials (seen in past with more “traditional” cytotoxics), as painful and tedious as that may be. Clinical trials We conclude that daunorubicin is dispensible during induction therapy in children with good early response to treatment -Andre Baruchel, MD Summary and Challenges Monash Children’s Cancer Centre currently treats between 25-30% of Victorian children diagnosed with malignancies 5th largest in Australia Ongoing clinical trial activities ~ enrolments New research initiatives, particularly lab based Neuroblastoma and brain tumour research Sustainability Collaborations and partnerships
