'Upcycling pathology': targeted next-generation sequencing is feasible in re-purposed haematoxylin and eosin and immunostained formalin-fixed paraffin-embedded sections in lung cancer biopsies.

Lung cancers are often diagnosed on small biopsy formalin-fixed paraffin-embedded (formalin-fixed paraffin-embedded) material.

The aim of this study is to investigate the feasibility of an alternative method to re-biopsy: that of re-purposing material from diagnostic slides for molecular testing.
