This multicentric prospective study evaluates the role of the margins resection and the ganglionic status when using a quality standard for the resection of adenocarcinoma of the head of the pancreas.

Primary objective:

• Evaluation of the prognosis role of the invasion of the margins on the overall survival after a standard resection of adenocarcinoma of the head of the pancreas.

Secondary objectives:

• Evaluation of the prognosis role of the invasion:

  • Of margins on the overall survival.
  • Of each margins (distal pancreatic margin, gastric, posterior, retro-venous, retro-arterial) on the overall survival.
  • Of the ganglionic group of the superior mesenteric artery and the other nodes.

Inclusion Criteria:

• A head of the pancreas tumor compatible with adenocarcinoma diagnosis
• tumor apparently removable
• patient aged from 18 to older
• signed consent

Non inclusion criteria:

• pregnancy, breast feeding
• patient in an urgency situation or patient with legal protection

Exclusion Criteria after surgery:

• tumor other than adenocarcinoma of the head of the pancreas.
• analysis of the margins not done with the defined criteria
