Summary
Brief summary (as posted)
Diagnostic tools are needed to identify mucinous cysts for further evaluation or follow-up respectively to identify cysts with HGD or invasive cancer at an early stage for surgical resection. Molecular genetic analysis of pancreatic cyst fluid is a new but rapidly evolving method to identify KRAS/GNAS oncogenic driver mutations in mucinous cysts and to identify tumour suppressor gene mutations which are involved in advanced cysts with HGD or carcinoma. The ongoing ZYSTEUS-study tries to implement DNA mutation analysis by Next Generation Sequencing in the diagnostic algorithm of pancreas cyst evaluation. The first aim is to distinguish mucinous from non-mucinous cysts. The second aim is to define relevant tumour suppressor gene mutations which are relevant to distinguish between LGD and HGD/carcinoma in mucinous cysts.

Arms (1)
- type
- EXPERIMENTAL
- label
- Suspected mucinous pancreas cyst
- description
- In all pancreas cysts \> 15mm and/or pancreas duct dilatation \> 5mm in patients who are fit for surgery EUS-guided pancreas cyst fluid aspiration is conducted. In cyst fluid CEA and lipase examination, cytology and Next Generation Sequencing is performed. After that, the pancreas cyst will be resected and histopathologically analysed.
