title: [Carcinoid of trachea and bronchus: a report of 20 cases].
abstract: OBJECTIVE
  To understand the biologic and clinical characteristics of carcinoid tumor of trachea and bronchus and to find out rational surgical indications and approaches.
  
  
  METHODS
  The clinical materials of 20 surgically treated patients with carcinoid of trachea and bronchus were retrospectively analyzed.
  
  
  RESULTS
  All but one patient received radical tumor resection. Operative complication occurred in 2 patients. Of the 20 patients, 13 suffered from typical carcinoids (TC) and 7 from atypical carcinoids (AC). Immunochemical staining revealed that both the typical and atypical carcinoids were of neuroendocrine origin. The 5-, 10- and 15-year survival rate of TC patients was 100.0%, 7/8 and 3/4 respectively. Of the 7 patients with AC, 6 had not yet been 5 years after operation but were still alive, and one patient died of remote metastasis 2 years after operation.
  
  
  CONCLUSIONS
  Surgical resection of carcinoid is indicated not only for early cases, but also for patients in stage III a and III b. The age and pulmonary function of the patients are the chief factors determining the surgical approach.
