在美国肿瘤死亡谱中，胰腺癌是第5大死因，总的5年生存率不足3％。目前，胰腺癌患者进行手术切除治疗是长期存活的唯一希望。但是肿瘤术后的局部和远处复发率却很高。有人提出，胰腺腺癌行胰腺切除术后进行辅助性放疗化疗可以显著提高患者中期、长期生存率。本实验前瞻性研究胰 In the United States tumor death spectrum, pancreatic cancer is the fifth leading cause of death and the overall 5-year survival rate is less than 3%. Currently, surgical resection of patients with pancreatic cancer is the only hope for long-term survival. However, the local and distant recurrence rates after tumor surgery are high. It has been proposed that adjuvant radiotherapy and chemotherapy after pancreatic resection of pancreatic adenocarcinoma can significantly improve patients’ mid-term and long-term survival. This study prospectively studied the pancreas
