Prediction of local tumor control and recurrence-free survival in patients with pancreatic cancer undergoing curative resection after neoadjuvant chemoradiotherapy.

Reduction rates of FDG uptake and CA19-9 levels were preoperative predictors of pathological response to NACRT. These biomarkers of local response had prognostic value in R-PDAC and BR-PDAC. The combined evaluation of these biomarkers allowed for reliable prediction of RFS after surgery.
