MetScore and classical–basal subtype intersect to define chemotherapy response and tumor microenvironment architecture in pancreatic ductal adenocarcinoma

Background Transcriptomic heterogeneity in pancreatic ductal adenocarcinoma (PDAC) is conventionally modeled along a single classical–basal axis, but this framework incompletely explains clinical behavior. We hypothesized that MetScore, a single-sample measure of metastatic colonization potential, defines a complementa...

Abstract A028: Metastatic potential defines an orthogonal axis of transcriptomic heterogeneity that predicts chemotherapy response and tumor microenvironment architecture in pancreatic ductal adenocarcinoma

Metastatic cell state is established as an independent and clinically actionable dimension of PDAC biology that complements classical–basal subtype classification and will inform chemotherapy backbone choice in KRAS inhibitor trials, as well as treatment following progression on KRAS inhibitor monotherapy.
