RESUMO
BACKGROUND: Today, in the management of pancreas cancers, achieving an R0 resection is one of the most powerful independent predictors of long-term survival. The aim of this study is to assess the clinical significance of intraoperative frozen section analysis of the pancreatic surgical margin for pancreatic cancer during pancreaticoduodemectomy. MATERIAL AND METHODS: We conducted a retrospective analysis of prospectively collected data of 37 patients who were operated for pancreatic head cancer and who were evaluated for surgical margin by frozen section analysis intraoperatively, between September 2013 and August 2014 in our center. The intraoperative biopsy reports were compared with final pathological reports. RESULTS: The mean age of the patients was 64.55(19-82) years (range), the mean tumor size was 3.96(1.16-6.25) cm (range) and the mean harvested lymph node number was 18.52(9-45) (range). In the intraoperative frozen section, one patient was positive for surgical margin (%2.7) who underwent total or complementary pancreatectomy. CONCLUSION: To secure a tumor-free margin by frozen section, intraoperatively, may increase R0 resection rate in pancreas cancers. The preoperative estimation of tumor margin by endoscopic ultrasonography, computerized tomography or magnetic resonance imaging mostly correlate with intraoperative findings, however in suspected cases intraoperative frozen section for margin determination should be performed.
