Abstract
PURPOSE: Aim of the study was to assess the value of extended lymphadenectomy for pancreatic cancer. MATERIALS AND METHODS: A retrospective analysis of 201 patients with pancreatic and ampullary cancer who underwent pancreatectomy with standard or extended lymph node dissection were analysed in order to compare the rate of perioperative complications and 5-year survival. RESULTS: Of 201 patients treated, 65 (32%) underwent standard (group I) and 136 (68%) extended (group II) lymphadenectomy. These two groups were similar with regard to age, gender, tumour location, advancement and radicality of performed resection. The mean operating time in the extended lymphadenectomy group was longer (383 +/- 81 min) compared to the standard group (357 +/- 64 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 group I (13.0 +/- 7.4). The overall morbidity and mortality rates were 43% and 6.9%, respectively without significant differences between both groups. The overall 5-year survival for pancreatic and ampullary cancer was 16.7% and 67.6% respectively, and was similar regardless the type of performed lymphadenectomy. 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%). CONCLUSIONS: Extended lymphadenectomy can be performed with similar morbidity and mortality rates compared to the standard resection. Benefits of 5-year survival can be achieved only in a limited group of patients with non-advanced pancreatic cancer.
