A New Prognostic Score Model for Pancreatic Ductal Adenocarcinoma

Development and Validation of a New Prognostic Score Model Combining TNM Stage With Immune Risk Factors for Postoperative Pancreatic Ductal Adenocarcinoma

The AJCC TNM staging system is the prevailing method in prognostic evaluation of pancreatic ductal adenocarcinoma (PDAC) at present , but it did not include factors such as the tumor immune microenvironment that are known to exert a profound impact on patients'clinical outcome. This study was aimed to develop a comprehensive and effective prognostic score model to predict prognosis and guide clinical management for postoperative PDAC patients.

Inclusion Criteria:

1. Pathologically confirmed PDAC
2. Achievement of surgical resection (including radical or palliative surgery)

Exclusion Criteria:

1. Lost to follow-up
2. Simultaneous presence of other tumors
3. Died in three months after surgery
