Clinical utility of 'Shaken' biopsies for whole-genome sequencing.

ABSTRACT:

Aims

Whole-genome sequencing (WGS) is beginning to be applied to cancer samples in the clinical setting. This ideally requires high-quality, minimally degraded DNA of high tumour cell content, while retaining sufficient tissue with excellent morphology for histopathological diagnosis and immunohistochemistry. The aim of this study was to investigate alternative ways of handling cancer samples to fulfil both diagnostic and molecular requirements.

Methods

Ex vivo biopsies were taken to investigate the feasibility of using cancer cells 'shaken' from the surface of a biopsy for WGS, while maintaining the tissue biopsy for histological diagnosis. WGS from the shaken cells was compared with the gold standard of a fresh-frozen (FF) biopsy. The procedure was piloted in the real-worl
