title: A clinicopathological study of postoperative pulmonary metastasis of uterine cervical carcinomas.
abstract: OBJECTIVE
  To investigate the clinicopathological backgrounds and prognostic factors of uterine cervical carcinomas metastatic to the lung.
  
  
  METHODS
  A total of 519 patients with invasive cervical carcinoma (Stage pTIb-IIb) treated by abdominal radical hysterectomy at the Saitama Cancer Center from January 1, 1976 to December 31, 1989 were analyzed clinicopathologically.
  
  
  RESULTS
  The frequencies of pulmonary metastasis were 6.4% (24/377) and 11.3% (16/142) in patients with negative and positive pelvic lymph nodes, respectively. Among 24 negative lymph node patients, 15 had pulmonary metastasis only. The overall 5-year survival rate of these 15 patients was 36% after relapse. Of the 15, the prognosis of 12 patients with 1-3 pulmonary metastases only was better, that is, 46% after surgical resection (mean size of resectable tumor = 2.8 cm) and/or chemotherapy. But the other patients died within 3.3 years after relapse.
  
  
  CONCLUSIONS
  The occurrence of pulmonary metastasis only, its number (1-3) and size (mean size = 2.8 cm), and no lymph node metastasis are important prognostic factors. For these patients, active surgical resection of the pulmonary lesion(s) and further chemotherapy are recommended in order to improve their prognosis.
