Background: Pancreatic ductal adenocarcinoma (PDAC) represents the fourth most common cause of cancer mortality and it is expected to become the second most common cause of cancer mortality by 2020 in the USA.
Objective: Which strategies for the detection and treatment of an early stage pancreatic adenocarcinoma and its precursor lesions are to be applied?
Results: Currently, there is no effective general screening program for pancreatic cancer due to the low incidence and the lack of an accurate and inexpensive diagnostic method; however, in patients with a positive history of hereditary pancreatic cancer or in patients with a known sporadic germline mutation that is associated with an increased risk of pancreatic cancer, frequent screening is highly recommended to detect and to treat early stage PDAC. Moreover, patients with a precursor lesion for pancreatic cancer (namely a mucinous pancreatic neoplasm) should undergo an oncological pancreatic resection to prevent the development of late stage pancreatic cancer. In future, additional biomarkers from a liquid biopsy, such as circulating tumor cells, exosomes or circulating tumor DNA may improve the early detection of pancreatic cancer.
Conclusion: The early detection and treatment of pancreatic cancer and its precursor lesions can help to improve the dismal prognosis of this aggressive tumor type.
