Dr Oliver Zill - Guardant Health Inc, Brentwood City, USA

Dr Zill speaks with ecancertv at ASCO 2016 about data from the clinical impact of sequencing circulating tumour DNA (ctDNA) with liquid biopsy techniques.

He reports on sampling somatic genomic profiles of over 15,000 patients with advanced-stage clinical cancer, and using liquid biopsy assays to determine cancer-type-specific frequencies and mutual exclusivity patterns among major driver alterations.

The overall accuracy of ctDNA sequencing in comparison with matched tissue tests was 87% (336/386), and Dr Zill highlights that accuracy increased to 98% when blood and tumour were collected less than six months apart.

He goes on to set out different classes of patient outcomes, and encourages the incorporation of liquid biopsy into patient surveillance on a wider scale.
