title: [Examination of a relapsing pattern of cases of completely resected non-small cell lung cancer].
abstract: OBJECTIVE
  The purpose of this research was to understand the clinical discovery of a relapse, relapse time, and the presentation of the first relapse of non-small cell lung cancer(NSCLC)by examining cases of relapse after complete resection of NSCLC. Objective and method. Cases of relapse after complete resection of NSCLC in our hospital were examined.
  
  
  RESULTS
  Fifteen cases were evaluated. In half of these cases, relapse was discovered owing to increased tumor marker values. Of the patients, 60%had a relapse within 2 years after resection and 20%had a relapse 5 years after resection. The first relapse was a local recurrence in 9 cases, lung metastasis in 5 cases, and distant metastasis outside the thoracic cavity in 3 cases.
  
  
  CONCLUSIONS
  The effectiveness of the tumor marker as a diagnostic parameter of relapse in NSCLC was demonstrated. Discovering distant metastases at the early postoperative period and relapse 5 years after resection are important.
