The volume ratio (VR), relative intensity ratio (RIRrim), CA19-9 ≥ 34 U/mL, and necrosis were independent predictors of high aggressiveness. The VR, RIRrim, CA19-9 ≥ 34 U/mL, and tumor boundary were independent predictors of poorer overall survival. The VR, RIRrim, CA19-9 ≥ 34 U/mL, tumor boundary, and tumor maximum size ≥ 3 cm were independent predictors of shorter disease-free survival.
St et al. (2026) studied this question.
