    Background
    

    Interstitial lung disease is mostly found in elderly male smokers who also have relatively high risks of developing lung cancer. For these patients, modality to treat malignancy is limited to prevent acute exacerbation of interstitial pneumonia. We analyzed the perioperative outcomes of this group of patients with both interstitial pneumonitis and resectable lung cancer with curative intent.

    Method
    

    We retrieved the characteristics and medical courses of consecutive patients who had undergone pulmonary resections from medical records. In this analysis, usual interstitial pneumonia (UIP) was characterized by the presence of basal predominant, subpleural reticular abnormalities with traction bronchiectasis and honeycomb cysts detected in bilateral lung field on chest computed tomography preoperatively. Pathological findings on surgical specimen were used confirmation of diagnosis. The incidence and outcomes of acute exacerbation within 30 days from operation were analysed.

    Result
    

    From 2015 to 2017, there were 1,477 patients who underwent pulmonary resection for primary lung cancer at our institute. Among them there were 81 (5.5%) patients diagnosed as UIP by specific findings on chest computed tomography. Of 81 patients evaluated, 68 (84.0 %) were men, the median age was 73 years (range, 55-88). For Eastern Cooperative Oncology Group (ECOG) performance status, all 81 patients were categorized in status 0. Seventy-four patients (91.4%) underwent lobectomy, 1 (1.2%) bi-lobectomy, 2 (2.5%) segmentectomy and 4 (4.9%) wide wedge resections for primary lung cancer. The mean duration of surgery was 129 mins (range, 54-316), and mean value for blood loss was 36.5 ml (range, 0-396). A complete resection (R0) was achieved in 79 cases (97.5%). Postoperative complications were observed in 19 patients (23.5%) including prolonged air leakage (n=4, 4.9%), late onset of air leakage (n=3, 3.7%), surgical site infection, chylothorax and cerebral infarction. Nine patients (11.1%) manifested acute exacerbation of interstitial pneumonia within 30 days after surgery. There were 3 post-operative deaths (3.7%) within 30 days after surgery. Two deaths (2.5%) were due to acute exacerbation of interstitial pneumonia and 1 (1.2%) case of SAH on 1POD.

    Conclusion
    

    Pulmonary resection for patients with interstitial lung disease led to 9 (11.1%) cases of acute exacerbation within 30 days from surgery. Mortality related to acute exacerbation was found only 2 cases (2.5%) at our hospital, which was tolerable postoperative outcome for pulmonary resection for lung cancer with curative intent.
