Case characteristics

A pancreatic cancer with liver metastasis.

Clinical diagnosis

Amplification of the EGFR gene is targetable in pancreatic acinar carcinoma.

Differential diagnosis

Histology and molecular biology are required for the diagnosis.

Laboratory diagnosis

Genetic testing provides information on targetable tumor mutation.

Imaging diagnosis

Computed tomography scan underlines liver metastasis necrosis.


The patient was treated with off-label usage of panitumumab.

Term explanation

This is the first report of EGFR amplification in acinar cell pancreatic cancer, and the first report of panitumumab efficacy in such disease.

Experiences and lessons

Our findings suggest that exome analysis may be a helpful tool to highlight targets in rare cancers, such as pancreatic acinar cell carcinoma. EGFR amplification in this pathology should be determined and could be used as biomarker to propose antiEGFR therapy.
