title: [Diagnosis and therapy of well-differentiated neuroendocrine lung tumors].
abstract: BACKGROUND
  Neuroendocrine tumours of the lung are uncommon malignant neoplasms. They represent a heterogeneous spectrum of disease, encompassing the well-differentiated neuroendocrine tumours through to small-cell lung cancer, which has a poor prognosis and only palliative therapeutic options for most patients. Due to the low incidence of well-differentiated lung tumours there is as yet little experience.
  
  
  METHODS
  Clinical records of 14 patients with well-differentiated neuroendocrine tumours of the lung were assessed retrospectively for patients' initial symptomatology, diagnostic procedures, therapy and results.
  
  
  RESULTS
  Eight lobectomies, 2 bronchoplastic lobectomies, 2 segmental resections, 1 bilobectomy and 1 wedge resection were performed; seven of them without regional lymphadenectomy. All patients were alive after a mean follow-up of 38 (2-96) months. Thirteen of 14 patients were free of complaints, twelve had no recurrences and returned to work.
  
  
  CONCLUSIONS
  Well-differentiated NET of the lung have an excellent prognosis after curative resection. Limited resections even without lymphadenectomy can be performed in some cases.
