title: Clinical impact of interstitial pneumonia following surgery for lung cancer.
abstract: BACKGROUND
  Operative morbidity in patients with lung cancer associated with perioperative interstitial pneumonia (IP) has emerged as a serious problem.
  
  
  METHODS
  We studied the clinical impact of perioperative related IP in 11 patients (IP group: 7 preoperative known, 4 acute onset) of 473 lung cancer patients who received a pulmonary resection. The IP group was compared to the remaining 462 patients (non-IP group). Demographic data, clinical presentation, and serum KL-6 levels were compared.
  
  
  RESULTS
  There were no differences in age, gender, type of surgery, and pulmonary function except for % DLco between the non-IP and IP groups. The IP group showed a higher in-hospital mortality (n=2: 18.3%) than that of the non-IP group (n=3: 0.6%) (P<0.005). Seven patients with underlying IP with high KL-6 levels showed an uneventful recovery. Two patients with postoperative onset of acute IP had a fatal course associated with elevation of serum KL-6 levels.
  
  
  CONCLUSIONS
  Postoperative development IP is a serious complication with high mortality, and serial measurement of KL-6 levels is useful to assess the activity of IP.
