To treat locally advanced cancer of the pancreatic body involving the common hepatic artery and/or celiac axis with perineural invasion in the nerve plexus surrounding these arteries, we have employed distal pancreatectomy with en bloc celiac axis resection (DP-CAR) without arterial reconstruction. DP-CAR has been performed in patients in whom the gastroduodenal artery and superior mesenteric artery could be preserved. Between April 1998 and December 2007, 37 patients underwent DP-CAR in our institution. The surgical margins were histologically clear (R0) in 35 (95%) patients. The postoperative morbidity rate was 59%. The primary complications were pancreatic fistula occurring in 19 patients and ischemic gastropathy in 5. Estimated overall 1- and 5-year survival rates were 72% and 17%, respectively, and the median survival was 21 months. The most common site of recurrence was the liver, where recurrence appeared significantly earlier than in other metastatic sites. DP-CAR, with its potential to achieve complete local control, has been confirmed to be advantageous only in cases that are unlikely to develop hepatic metastasis. In principle, since 2006 patients who have undergone DP-CAR also receive postoperative adjuvant chemotherapy. Patients must achieve feasible general status within 3 months after DP-CAR to be able to start adjuvant chemotherapy.
为治疗累及肝总动脉和/或腹腔干且在这些动脉周围神经丛有神经侵犯的局部晚期胰体癌,我们采用了不进行动脉重建的整块腹腔干切除远端胰腺切除术(DP-CAR)。DP-CAR已在能保留胃十二指肠动脉和肠系膜上动脉的患者中实施。1998年4月至2007年12月期间,我院有37例患者接受了DP-CAR。35例(95%)患者的手术切缘组织学检查为阴性(R0)。术后发病率为59%。主要并发症为19例发生胰瘘,5例发生缺血性胃病。估计1年和5年总生存率分别为72%和17%,中位生存期为21个月。最常见的复发部位是肝脏,肝脏复发明显早于其他转移部位。DP-CAR有可能实现完全局部控制,已证实仅在不太可能发生肝转移的病例中具有优势。原则上,自2006年以来,接受DP-CAR的患者术后也接受辅助化疗。患者必须在DP-CAR后3个月内达到可行的一般状况才能开始辅助化疗。
