Advanced Molecular Diagnostics (AMD)
Despite significant progress made in the treatment of children with cancer, it remains the leading cause of disease related death in children, with significant short and long term morbidities due to treatment toxicity. Assessment of minimal residual disease in these cases can profoundly refine risk-directed therapy to guide treatment decisions. Identifying non-responders to current therapy, subsequently switching regimens, could save precious time as well as spare adverse side-effects resulting from a non-effective therapy. Similarly, the ability to identify early disease recurrence would enable earlier intervention and superior outcome. Our approaches include techniques to identify any cancer cell DNA circulating in the body (liquid biopsy), resulting in cheaper, less invasive and more sensitive monitoring of cancer occurrence, response to therapy and recurrence leading to improved patient survival.

> Dr Jonathan Karpelowsky, Liquid Biopsy Research Group Leader, email: Jonathan.Karpelowsky@health.nsw.gov.au
Jonathan is a Paediatric Surgical Oncologist at the Children’s Hospital at Westmead and Conjoint Associate Professor at the University of Sydney. He dedicates his clinical career to improving the outcomes of children and adolescents with solid tumours. Understanding the clinical challenges in treating cancer enables him to ask translational questions in order to improve the care of these patients. Through his basic science work on liquid biopsies he is hoping to translate this exciting novel technology to impact on treatment paradigms in children with solid tumours.
