The objective of the present registry is the creation of a prospective registry collecting clinico-pathological and genomic data, along with survival outcomes, of individuals diagnosed with PDAC at or before the age of 55 years old. This registry is intended with the aim of using collected data for future clinical trials, both prospective and retrospective.

Inclusion Criteria:

• Age ≤55 years old at the time of diagnosis of pancreatic cancer
• Age ≥ 18 years
• Written informed consent obtained.

Exclusion Criteria:

• Any pancreatic neoplasm other than pancreatic cancer (e.g. cholangiocarcinoma, ampullary cancer,duodenal cancer, non-invasive mucinous cystic neoplasm, pancreatic intra-epithelial neoplasia 1 and 2, non-invasive intraductal papillary mucinous neoplasm, serous cystic neoplasm, pseudo papillary solid tumor, neuroendocrine tumor)
• Absence of informed consent.
• Age < 18 years or > 55 years old at the time of diagnosis of pancreatic cancer

The target population is represented by individuals who have received a pathological diagnosis of pancreatic cancer before the age of 55 years old (namely, EO-PDAC patients). No subject will be financially compensated for their participation.
