Background!#!The role of surgery for circumscribed synchronous hepatic lesions of the pancreatic ductal adenocarcinoma (PDAC) remains controversial. Thus, the aim of our study was to compare survival outcome (OS) after surgery of patients with hepatic metastases (M1surg) to patients with only localized disease.!##!Methods!#!Correlation analysis of clinicopathological data and OS after resection of M1surg patients and patients with localized PDACs (M0) was performed. Patients were included for survival analysis only if a complete staging including perineural, venous and lymphatic invasion was available.!##!Results!#!Out of the study collective, 35 patients received extended surgery (M1surg), whereas 131 patients received standardized surgery for localized disease (M0). Length of hospitalization and mortality was similar in both groups. FOLFIRNOX as an adjuvant treatment regime was administered in ~ 23 and ~ 8% of M1surg and M0 patients, respectively. In subgroup analysis of R0 resected patients and in multivariate analysis of the total cohort, there was no difference in overall survival between both groups. Only the resection status (R1 vs R0) and venous invasion (V1) were identified as independent prognostic factors. Site of recurrence in R0 resected M1surg patients and in M0 patients were homogenously distributed.!##!Conclusion!#!This is the first study demonstrating a survival benefit after extended surgery for synchronously hepatic-metastasized PDACs. We found no difference in survival outcome of metastasized patients when compared to patients with localized disease. FOLFIRINOX as an adjuvant treatment regime for resected M1surg presumably is worthwhile. Larger multicenter studies are still needed to validate our results.
