苗毅(南京医科大学第一附属医院胰腺中心)胰腺癌病人平均肿瘤直径仅为3 cm,而5年存活率却仅为5%~8%,虽然经过几代外科医师的努力,近40年来,存活率几乎没有提高,仅有20%的病人有机会行根治性手术。究其原因,除了与不良生物学行为有关外,另一个重要的原因是肿瘤侵犯了邻近的血管。恰恰由于这样几条重要的血管穿过胰腺,导致手术难度非常高。胰腺癌不可切除的最常见的原因是远处转移和血管侵犯。可见,血管侵犯是制
Miaoyi (First Affiliated Hospital of Nanjing Medical University Pancreatic Center) The average tumor diameter of pancreatic cancer patients was only 3 cm, while the 5-year survival rate was only 5% to 8%, although after several generations of surgeons efforts, nearly 40 years , Almost no increase in survival rate, only 20% of patients have the opportunity to undergo radical surgery. The reason, in addition to the adverse biological behavior, the other important reason is that tumors invade the adjacent blood vessels. It is precisely because of these few important blood vessels through the pancreas, resulting in surgery is very difficult. The most common causes of unresectable pancreatic cancer are distant metastasis and vascular invasion. Visible, vascular invasion is the system
