随着胰腺影像学和外科手术技巧的发展,外科医生在“可切除的”胰腺癌与“局部进展的”胰腺癌之间划分出一类“边缘可切除”胰腺癌。这一大类肿瘤包括部分累及肝动脉、门静脉、肠系膜上动静脉,并且其受累的血管有切除与重建可能的胰腺癌。对“边缘可切除”胰腺癌施行根治性手术,有助于提高以往被认为是“无法切除”的胰腺癌的手术切除率,但是根据现有的资料统计,“边缘可切除”肿瘤的术后切缘阳性发生率较高,直接影响患者的预后。因此,术前应对肿瘤进行准确的分期分级,并联合新辅助治疗有可能为此类患者获得RO切除创造条件,并改善预后。
With the development of pancreatic imaging and surgical techniques, surgeons have delineated a category of “resectable” pancreatic cancer between “resectable” pancreatic cancer and “locally advanced” pancreatic cancer. This large group of tumors includes the hepatic artery, portal vein, superior mesenteric artery and vein, and the vessels involved in the resection and reconstruction of possible pancreatic cancer. Radical resection of “resectable” pancreatic cancer can help improve the surgical resection rate of pancreatic cancer that was previously considered to be “unresectable”, but according to available data, “resectable margins ”The higher incidence of posterior margin of the tumor, a direct impact on the prognosis of patients. Therefore, accurate preoperative staging of tumors should be combined with neoadjuvant therapy may create conditions for these patients to obtain RO resection, and improve the prognosis.
