[The efficacy of perioperative administration of steroid and erythromycin in the surgery for lung cancer complicated with interstitial pneumonia].

OBJECTIVES

We evaluated the efficacy of perioperative administration of steroid and erythromycin in surgery for lung cancer complicated with interstitial pneumonia (IP) to prevent postoperative acute exacerbation.

PATIENTS AND METHODS

We operated on 21 lung cancer patients with IP for 10 years. The patients were given 400 mg of erythromycin over 1 week before surgery and re-administered on the 1st operative day. The patients were also given 125 mg of methylprednisolone intravenously just before operation and continued until the 2nd operative day.

RESULTS

Lobectomy was performed in 16, segmentectomy or partial resection in 2 each, and completion pneumonectomy in 1. Three patients developed acute exacerbation of IP, but it occurred after the re-operation due to postoperative complications in 2. We experienced no operative death within 30 days, however, 2 died during the hospital stay due to multiple organ failure and sepsis. Seven of 21 patients had postoperative complications; air leakage over 1 week in 4, arrhythmia in 3, and atelectasis, postoperative bleeding, and pneumonia in 1 each, the morbidity rate was 33%.

CONCLUSIONS

We conclude that the administration of steroid and erythromycin in surgery for lung cancer with IP was suspected the usefulness to prevent a postoperative acute exacerbation of IP.
