Jacob Scott is a veteran of the US Navy submarine force turned academic physician-scientist. His lab pursues research decomposing the complexity of cancer through mathematical modelling and the biological and clinical validation of these models. With an educational background in physics, medicine, mathematics and engineering Jake has a unique perspective on cancer and systems biology and communicates and collaborates with professionals across many disciplines. After medical school at Case Western Reserve University, Jake pursued a residency in Radiation Oncology at Moffitt Cancer Centre. Feeling frustrated with the one-size-fits-all approach in modern oncology, he took a hiatus to pursue a PhD in mathematical biology at the University of Oxford, where his thesis focused on the role of heterogeneity and evolution, both genetic and microenvironmental, on cancer evolution and radiation response – a theme which is now his laboratory’s focus.

The advent of personalized oncology provided the promise of using a patients genetic information to give us therapeutic strategies tailored specifically to them. While this has provided a number of successes for patients with specific, actionable mutations, the reach has been limited, with estimates as low as 10% of patients receiving truly personalized care based on their genomics. In this talk, I will provide a roadmap to using a combination of experimental and publicly available gene expression data, together with phenotypic measures, to derive gene signatures predictive of therapeutic response for any patient. Using, as examples, signatures predictive of radiation therapy and cisplatin response (the two most commonly prescribed agents in oncology), I will provide a road map for a future where we can treat every patient with the drugs and radiation that best suit their specific tumour, rather than using one-size-fits-all therapy based on large clinical trials.

This will focus on two papers in Lancet Oncology:
