title: Surgical treatment of pulmonary recurrence after hepatectomy for colorectal liver metastases.
abstract: OBJECTIVE
  Although pulmonary recurrence is frequent among the extrahepatic recurrences after hepatectomy, the efficacy of surgical treatment for pulmonary recurrence after hepatectomy has not been confirmed. Surgical resection of pulmonary recurrence after hepatectomy for colorectal metastases was reviewed retrospectively to evaluate the survival benefit.
  
  
  METHODS
  From 1990 to 1995, 10 of the 17 patients with pulmonary recurrence after hepatectomy for colorectal metastases underwent surgical treatment. Ten patients underwent resection of pulmonary recurrence.
  
  
  RESULTS
  Operative mortality was 0%, and a postoperative complication was observed in 1 patient after pulmonary metastasectomy. The overall 5-year survival rate after pulmonary metastasectomy was 10.0%, and the median survival was 21.7 (range: 2.4-77.9) months. One patient underwent resection two times for remnant lung recurrence after first lung metastasectomy, and is alive with no evidence of recurrence 77.9 months after the first pulmonary resection, and 50.7 months after the third pulmonary resection. In 3 patients with well-differentiated adenocarcinoma, the median survival time was 6.2 months (range: 2.4-9.7). The other hands, 7 patients with moderately differentiated adenocarcinoma have a longer median survival time of 29.2 months (range: 16.0-77.9).
  
  
  CONCLUSIONS
  Pulmonary metastasectomy after hepatectomy for metastases from colorectal cancer is a safe treatment, and might offer prolonged survival for highly selected patients.
