[Surgical treatment of pancreatic adenocarcinoma using cephalic duodenopancreatectomy (Part 2). Long term follow up after 204 cases].

Introduction: Surgery is the accepted treatment in adenocarcinoma of the head of the pancreas; however, the long-term survival continues to be low. The aim of this study is to define prognostic factors of long-term survival after cephalic duodenopancreatectomy due to pancreatic adenocarcinoma.

Material And Methods: We have collected data on the treatment of adenocarcinoma of the head of the pancreas (ADHP) by means of a cephalic duodenopancreatectomy (CDP) performed n the Bellvitge University Hospital (Barcelona) from 1991 to 2007.

Results: A total of 204 CDP due to ADHP were performed. The histology showed that the resected tumour was larger than 3cms in 70 cases, with lymphatic infiltration in 73%, perineural invasion in 89%, and lymphatic involvement in 89%. More than 15 lymph nodes were resected in 120 patients. A total of 113 (60%) patients received adjuvant treatment after surgery. There were 148 (73%) deaths, of which 55 (27%) were alive at closure. The actual mean survival was 2.54 years (95% CI; 2.02-3.07) and an actuarial survival at 5 years of 13.55% (95% CI; 7.69-19.41). The study of mortality risk factors showed that, female gender, absence of peri-operative transfusion (p=0.003), the resection of more than 15 lymph nodes during the operation (P=0.004), and the administration of adjuvant treatment (p=0.004) had a better long-term prognosis. The multivariate analysis showed that transfusion and gender were the most significant variables.

Conclusions: Surgery of head of the pancreas adenocarcinoma must include an adequate lymphadectomy, and must be performed with a low morbidity and without the need of a peri-operative transfusion.
