Pancreatic cancer patients with longer and denser basal microvilli have a dismal prognosis. (A, B) Kaplan–Meier curves for RFS and OS stratified by basal microvilli parameters in the cohort. Median values of basal microvilli length or density were used as a parameter (length: shorter, <11.17 μm; longer, ≥11.17 μm; density: lower, <6.04/100 μm²; higher, ≥6.04/100 μm²; index: lower, <2.14; higher, ≥2.14). Cox regression was used to assess the hazard ratios; the log‐rank test was used to test the P values.
