What is a liquid biopsy based test?

Liquid Biopsy

Certain lung cancer patients are not good candidates for tissue biopsy as this is an invasive procedure that carries risk. Liquid biopsy offers a non-invasive alternative for clinicians to identify clinically relevant biomarkers in patients to guide treatment decisions.

A liquid biopsy test looks for cancer cells or cell-free DNA (cfDNA) from a tumor that is circulating in the blood.¹ Obtaining blood samples is less invasive compared to traditional tissue biopsies.

Opportunities for liquid biopsy

In non-small cell lung cancer (NSCLC), Epidermal Growth Factor Receptor (EGFR) testing is not performed in ~20% of eligible patients due to unavailable or insufficient tissue.²

Liquid biopsy can help overcome complications of a lung biopsy and is playing an increasing role as a companion diagnostics in cancer management.
