[Perioperative management for lung cancer with interstitial pneumonia].

The purpose of this study was to review perioperative managements from the clinical features and the postoperative course of lung cancer patients with interstitial pneumonia (IP). Twenty-two patients with IP were divided into 2 groups: the acute exacerbation (AE) group (6 patients) and the non-acute exacerbation (NAE) group (16 patients). There was no significant difference in the patient background between the 2 groups. In hematological examination, KL-6 levels were significantly higher in the AE group than in the NAE group. There was no significant difference in the respiratory function tests in the both groups, and the heart rate after 2 flights test was significantly higher in the AE group than in the NAE group. There was no significant difference in operation-related factors, tumor-related factors and the postoperative course in the both groups. No postoperative death occurred in our 22 patients probably due to adequate treatments of IP which was managed by our detailed manual. Long-term follow-up for lung cancer patients with IP undergoing surgical intervention is needed to prevent AE.
