    Abstract:
    BACKGROUND: Despite improvements in surgical technique and adjuvant therapy models, the overall outcome for patients with pancreatic cancer has not significantly improved over the recent decades. The aim of the study was to assess the value of extended lymphadenectomy for pancreatic cancer. STUDY DESIGN: We performed a retrospective analysis of 136 patients with pancreatic cancer who underwent pancreatectomy and standard or extended lymph node dissection, to compare the rate of perioperative complications and 5-year survival. RESULTS: Of 136 patients treated, 43 (32 %) underwent standard (group I) and 93 (68 %) extended (group II) lymphadenectomy. Both groups were comparable with regard to various clinicopathological factors including patients' age, gender, tumour location, advancement and radicality of performed resection. The mean operative time in the extended group was longer (385 +/- 78 min) than in the standard group (359 +/- 62 min) but observed difference was insignificant. Similarly, there were no significant differences with respect to transfused blood and plasma units. The mean number of resected lymph nodes was significantly (p < 0.001) higher in group II (29.0 +/- 17.7) compared to I (13.0 +/- 7.4). The overall morbidity and mortality rates were 43 % and 6 %, respectively, without significant differences between both groups. The overall 5-year survival was 16.7 % and was similar regardless the type of performed lymphadenectomy. However, patients with node-negative pancreatic cancer following extended lymphadenectomy had significantly higher (p < 0.01) 5-year survival (48 %) compared to the standard resection (22 %). CONCLUSION: Extended pancreatoduodenectomy can be performed with similar morbidity and mortality rates as the standard procedure. However, only patients with non-advanced pancreatic cancer are likely to benefit of 5-year survival.
