Functional diagnostics using fresh uncultured lung tumor cells to guide personalized treatments

Abstract: SUMMARYFunctional profiling of a cancer patient’s tumor cells holds potential to tailor personalized cancer treatment. Here we report the utility of Fresh Uncultured Tumor-derived EpCAM+ epithelial Cells (FUTC) for ex vivo drug response interrogation. Analysis of murine Kras mutant FUTCs demonstrated pharmacological and adaptive signaling profiles comparable to subtype-matched cultured cells. Applying FUTC profiling on non-small cell lung cancer patient samples, we generated robust drug response data in 18 of … Show more

“…To address methodological limitations in evaluation of cancer treatment approaches, we and others have developed and validated methods for NSCLC functional diagnostics, including conditionally reprogrammed cells (CRCs) (Liu et al, 2012), long-term 3D organoid culture (Kim et al, 2019, Sachs et al, 2019) and analysis of functional uncultured tumor cells (FUTCs) (Talwelkar et al, 2021). These ex vivo models can complement GEMMs in preclinical cancer research.…”
