Introduction:
Most frequent sites of metastasis from lung cancer are the liver, brain and adrenal. Pancreas is an infrequent site of solitary metastasis from the lung primary with limited treatment options. There is insufficient data on the prognosis and optimal management of such cases.
Case description:
We report a case of 44-year-old gentleman diagnosed with locally advanced lung adenocarcinoma Stage T4N3 who was treated radically with chemoradiation therapy, followed by a relapse of solitary pancreatic metastasis, which was treated with targeted therapy, erlotinib, due to the presence of epidermal growth factor receptor (EGFR) mutation.
Practical implications:
This case reports an excellent radiological and symptomatic response in a patient who received erlotinib for advanced non-small-cell lung cancer (NSCLC). The use of EGFR-tyrosine kinase inhibitors has led to better prognosis and longer progression-free survival for patients with advanced NSCLC. However, the long-term survival of patients with metastatic NSCLC is limited.
