Pancreatic cancer in patients with chronic pancreatitis: a challenge from a surgical perspective☆

Abstract 

Chronic pancreatitis (CP) is generally considered as a risk factor for pancreatic adenocarcinoma (PAC). However, the cumulative risk differs among the epidemiological studies. In the individual patient, the differential diagnosis between PAC and CP cannot be always resolved preoperatively and even intraoperatively. In those cases, the uncertainty can only be answered with histological studies of the resected specimen after a radical resection, provided that this type of surgery can be performed with a reasonable risk in a surgically fit patient. The type of resection depends on the location of the suspicious mass. For masses in the tail of the pancreas, a distal pancreatectomy is the procedure of choice. For suspicious lesions in the head of the pancreas, a pancreatoduodenectomy (PD) should be performed. The surgeon and the patient should also acknowledge that a radical resection will occasionally be performed for a suspected malignancy only to find that another etiology (i.e. CP) accounts for the suspicious pancreatic mass. In the presence of a strong suspicion for an underlying malignancy in a patient with head dominant CP, PD should probably be preferred over the newer organ-preserving Beger and Frey procedures, since it is an adequate procedure for both CP and PAC.
