Distinct morphologic properties of cancer cells in low and high delta
tumors. (A) CT scans of 5 patients who underwent upfront surgery. (B) Cancer
cell lines from the 5 patients in (A) (MDA-PATC50, −69, −66,
−102, and −118). (C) The membrane axis ratio, stratified by the
delta measurement (Wilcoxon test; n.s., not significant,
****P<0.0001). A high membrane axis ratio indicates a
rounder shape. (D) Western blots of the 5 cell lines for markers of the
epithelial-to-mesenchymal transition. (E) Nuclear morphology, measured from
segmentation on histology. Left panel, nucleus axis ratio was measured from
H&E-stained slides of 12 patients in a prospective protocol of
intraoperative gemcitabine infusion during PDAC resection (Supplementary Table S1); (F)
Physical properties of PDAC stratified by delta measurement, as measured by
Volumetric AUC (VAUC) for patients in Supplementary Table S2 (left) and
Supplementary Table
S3 (right), and (G) by tumor axis ratio from CT scans with orthogonal
measurements on a single axial slice at greatest tumor size for patients in
Supplementary Table
S3 (Wilcoxon test, P<0.0001).
