  Agree (%) Disagree (%) Unsure (%) Missing (%)
the resectability can be assessed by:
 CA19–9 392(55.6) 254(36.0) 6(0.9) 53(7.5)
 CT 632(89.7) 56(7.9) 1(0.1) 16(2.3)
 MRI 597(84.7) 77(10.9) 1(0.1) 30(4.3)
 PET 445(63.1) 173(24.5) 9(1.3) 78(11.1)
 ERCP 419(59.4) 208(29.5) 3(0.4) 75(10.6)
 Selective angiography 506(71.8) 122(17.3) 4(0.6) 73(10.4)
CT Loyer stagesa
 Type A: resectable 572 (81.1) 80(11.4) 18(2.6) 35(5.0)
 Type B: resectable 534(75.7) 122(17.3) 5(0.7) 44(6.2)
 Type C: resectable in half of patients 483(68.5) 146(20.7) 4(0.6) 72(10.2)
 Type D: resectable in half of patients 438(62.1) 168(23.8) 8(1.1) 91(12.9)
 Type E: non-resectable 411(58.3) 183(26.0) 4(0.6) 107(15.2)
 Type F: non-resectable 540(76.6) 107(15.2) 8(1.1) 50(7.1)
  1. Type A: Fat plane seperates the tumor and/or the normal pancreatic parenchyma from adjacent vessels; Type B: normal parenchyma separates the hypodense tumor from adjacent vessels; Type C: hypodense tumor is inseparable from adjacent vessels, and the points of contact form a concavity against the vessels; Type D: Hypodense tumor is inseparable from adjacent vessels, the points of contact form a concavity against the vessels or partially encircle the vessels. Type E: hypodense tumor completely encircles the vessel; Type F: hypodense tumor occludes the vessels
