(Objectives) The aim of the present study was to investigate both the benefits and adverse effects of prophylactic administration of methylprednisolone for interstitial pneumonia (IP) after pulmonary resection.<BR>(Methods) We reviewed 41 patients with primary lung cancer who underwent complete resection. Of these, 24 patients who had two or more risk factors for postoperative IP were given 125mg of methylprednisolone intravenously just before the thoracotomy. The risk factors included male gender, Brinkmann index >600, and the presence of interstitial changes on chest CT.<BR>(Results) The serum CRP on the third postoperative day (POD) was significantly lower in the steroid group than in control (8.5±5.2mg/dlvs. 13.3±4.2mg/dl, p=0.011) while it was not different between those two groups on the seventh POD (1.9±1.3 vs. 2.0±2.0, p=0.942). Both the mean days of postoperative hospital stay and the disease-free survival were not different between the two groups.<BR>(Conclusion) Prophylactic administration of methylprednisolone suppressed the inflammatory response during the early postoperative days, and no adverse effect on wound healing or disease-progression was identified.
