Clinical Significance of Plasma Apolipoprotein-AII Isoforms as a Marker of Pancreatic Exocrine Disorder for Patients with Pancreatic Adenocarcinoma Undergoing Chemoradiotherapy, Paying Attention to Pancreatic Morphological Changes

Figure 2

A case of UR-LA PDAC showing drastic reduction of TS, MPDD, and PPV after CRT ((a) before CRT and (b) after CRT. The time interval of CT images between (a) and (b) is 3 months). Arrow head shows main pancreatic duct (a1) and (b1). Cross-section CT images showing the reduction of TS (59.4→52.2 mm) after CRT (a2) and (b2). Coronal section CT images showing the reduction of portal vein invasion after CRT (a3) and (b3). Cross-section CT images showing the reduction of MPDD (7.6→3.7 mm) and PPV (39.8→29.3 ml) after CRT. UR-LA PDAC: unresectable pancreatic ductal adenocarcinoma, TS: tumor size (sum of short and long axis), MPDD: main pancreatic duct diameter, PPV: pancreatic parenchymal volume excluding tumor volume, and CRT: chemoradiotherapy.
