Figure 1 Computed tomography changes in pancreatic cancer before and after neoadjuvant chemotherapy. A-C: Computed tomography (CT) before neoadjuvant chemotherapy revealed pancreatic cancer with multiple lymph node metastases (red arrow); D: Pancreatic cancer invaded the portal vein wall (red arrow); E-G: After 2 cycles of neoadjuvant chemotherapy, CT showed a decreased diameter of pancreatic cancer and a reduced number of lymph nodes (red arrow); H and I: After 4 cycles of neoadjuvant chemotherapy, CT showed an obviously decreased diameter of pancreatic cancer and a reduced number of retroperitoneal lymph nodes; J: The superior mesenteric vein had a regular shape.
