Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Patients with a mucinous pancreas cyst

    Number of patients with the preoperative diagnosis of a mucinous pancreas cyst (numerator) in correlation with the number of patients with a mucinous pancreas cyst confirmed by surgery (denominator)

    From EUS-guided fine needle aspiration of pancreas cyst fluid up to seven days

  • Pancreas cyst with HGD or carcinoma

    Number of patients with the preoperative diagnosis of a HGD/carcinoma pancreas cyst (numerator) in correlation with the number of patients with a HGD/carcinoma pancreas cyst confirmed by surgery (denominator)

    From EUS-guided fine needle aspiration of pancreas cyst fluid up to seven days

Study Arms (1)

Suspected mucinous pancreas cyst

EXPERIMENTAL

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.

Diagnostic Test: Next Generation SequencingDiagnostic Test: CEA and lipaseDiagnostic Test: CytologyDiagnostic Test: Histology of resected pancreas cyst

Interventions

DNA Mutational Analysis in pancreas cyst fluid concerning KRAS/GNAS-mutations and mutations in tumor supressor genes

CEA and lipaseDIAGNOSTIC_TEST

Measuring CEA and lipase level in pancreas cyst fluid: CEA \> 192 ng/ml and lipase \> 200 U/l = mucinous cyst
