Efficacy and safety of laparoscopic radical resection following neoadjuvant therapy for pancreatic ductal adenocarcinoma: A retrospective study

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.

Figure 2 Kaplan-Meier curves of overall survival and disease-free survival. A: The 1- and 2-year survival rates were both 50%; B: The 1- and 2-year disease-free survival rates were 60.00% and 40.00%, respectively.
