title: A case of amylase-producing small cell lung cancer.
abstract: OBJECTIVE
  To assess the relationship between amylase level and small cell lung cancer in a patient with hyperamylasemia of non-pancreatic disease.
  
  
  METHODS
  Case report with correlation analysis between hyperamylasemia and small cell lung cancer while considering immunohistochemistry study and response to chemotherapy.
  
  
  RESULTS
  We observed a strong correlation between amylase levels and small cell lung cancer. Immunohistochemistry findings suggested that amylase was produced by the lung cancer in this case.
  
  
  CONCLUSIONS
  Amylase can be considered as a tumor marker reflecting response to chemotherapy and disease relapse.
