DR-489 Adapting the DeepTumour Algorithm to Plasma Whole Genome Sequencing

The major factor predicting a human cancer’s behaviour is its organ of origin. However, roughly 3% of the time a cancer presents with metastatic disease and no primary can be determined even after a thorough radiological survey. We have previously used whole genome sequencing (WGS) data from the ICGC/TCGA PanCancer Analysis of Whole Genomes (PCAWG) and the Hartwig Medical Foundation to develop an AI system that distinguishes among 32 major cancer types using information derived from the genome. The work proposed here will extend the algorithm to determine the tumour type based on a sample of the patient’s blood.
