AIM: To investigate predilection sites of recurrence of @entity788 by computed tomography (CT) in follow-up after surgery. METHODS: Seventy seven @entity1 with recurrence after @entity788 surgery were retrospectively identified. The operative technique, R-status, T-stage and development of @entity5 markers were evaluated. Two radiologists analyzed CT scans with consensus readings. Location of local recurrence, lymph node recurrence and organ metastases were noted. Surgery and progression of findings on follow-up CT were considered as reference standard. RESULTS: The mean follow-up interval was 3.9    1.8 mo, with a mean relapse-free interval of 12.9    10.4 mo. The predominant site of recurrence was local (65%), followed by lymph node (17%), liver @entity3 (11%) and peritoneal carcinosis (7%). Local recurrence emerged at the superior mesenteric artery (n = 28), the hepatic artery (n = 8), in an area defined by the surrounding vessels: celiac trunk, portal vein, inferior vena cava (n = 22), and in a space limited by the mesenteric artery, portal vein and inferior vena cava (n = 17). Lymph node recurrence occurred in the mesenteric root and left lateral to the aorta. Recurrence was confirmed by surgery (n = 22) and follow-up CT (n = 55). Tumor markers [ @entity1735 antigen 19-9 (CA19-9), @entity787 ( @entity787 )] increased in accordance with signs of recurrence in most cases (86% CA19-9; 79.2% @entity787 ). CONCLUSION: Specific changes of local and lymph node recurrence can be found in the course of the cardinal peripancreatic vessels. The superior mesenteric artery is the leading structure for recurrence.
