十二指胸腺癌切除后的预后较胰腺癌或胆总管下端癌为佳。90年代前采用局部切除，5年生存率为0％～50％。近年胰十二指肠切除术的比例已自40％～60％增至62％～90％，故其5年生存率已逐渐增至60％。为了进一步改善生存率，更开展了扩大淋巴结清扫术，但最终的结果与胰腺有无浸润 The prognosis of resection of the thymic thymus cancer is better than that of pancreatic cancer or common bile duct cancer. Local resection was performed before the 1990s, and the 5-year survival rate was 0% to 50%. In recent years, the proportion of pancreatoduodenectomy has increased from 40% to 60% to 62% to 90%, so the 5-year survival rate has gradually increased to 60%. In order to further improve the survival rate, expanded lymph node dissection was performed, but the final result and pancreatic infiltration
