BACKGROUND AND STUDY AIMS: There have been concerns regarding tumor cell seeding along the needle track or within the peritoneum caused by preoperative endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The aim of this study was to evaluate whether preoperative EUS-FNA is associated with increased risk of stomach/peritoneal recurrence and whether the procedure affects long term survival. METHODS: The records of patients diagnosed with malignant solid and cystic pancreatic neoplasms who underwent surgery with curative intent between 1996 and 2012 were reviewed. RESULTS: A total of 256 patients with similar baseline characteristics were included: 48 patients in the non-EUS-FNA group and 208 in the EUS-FNA group. Recurrence data were available for 207 patients. Median length of follow-up was 23 months (range 0 - 111 months). A total of 19 patients had gastric or peritoneal recurrence; 6 (15.4 %) in the non-EUS-FNA group vs. 13 (7.7 %) in the EUS-FNA group (P = 0.21). Three patients had recurrence in the stomach wall: one (2.6 %) patient in the non-EUS-FNA group vs. two patients (1.2 %) in EUS-FNA group (P = 0.46). A total of 16 patients had peritoneal recurrence: 5 patients (12.8 %) in the non-EUS-FNA group and 11 patients (6.5 %) in the EUS-FNA group (P = 0.19). In a multivariate analysis, undergoing EUS-FNA was not associated with increased cancer recurrence or decreased overall survival. CONCLUSION: Pre-operative EUS-FNA was not associated with an increased rate o...
