About 5,300 new cases of pancreatic adenocarcinomas are diagnosed each year in France. At the time of diagnosis, an efficient carcinologic surgery will not be possible for nearly 80% of patients, in relation to locoregional extension or metastatic dissemination. After surgical resection, the median survival of resected patients ranges from 12 to 20 months, with a high rate of loco-regional or metastatic relapses. Numerous therapeutic trials, adjuvant or neo-adjuvant, have been conducted in aim of which to improve locoregioanl control and survival rates. Chemotherapy and chemoradiotherapy represent adjuvant treatments. In one trial, a chemotherapy regimen with 5-fluorouracil and folinic acid (FUFOL) has proven its efficience for survival improvement by comparison to chemoradiotherapy and is at this time the reference treatment in Europe. In another trial, using adjuvant gemcitabine results in an improvement in disease-free survival. Some phase III trials are in progress to evaluate new therapeutic strategies. The aim of neoadjuvant strategy using chemoradiotherapy is to enhance the rate of complete resections and by the way local control. This is under evaluation. This paper presents a summary of adjuvant and neoadjuvant trials for patients with potentially resectable pancreatic adenocarcinoma.
