Steroid-responsive interstitial lung disease in patients receiving 2'-deoxy-5-fluorouridine-infusion chemotherapy. A report of three cases.

Abstract

BACKGROUND:

Continuous infusion of 2'-deoxy-5-fluorouridine (FUdR) has shown promise in its activity against metastatic renal cell carcinoma. Its side-effect profile is dominated by gastrointestinal toxicity; there are no known adverse pulmonary reactions. To the authors' knowledge, this is the first report on the development of lung toxicity in three patients receiving FUdR-infusion chemotherapy for metastatic renal cell carcinoma.

METHODS:

The hospital charts of three patients presenting with pulmonary symptoms during FUdR chemotherapy were reviewed. A literature search was performed regarding FUdR-related pulmonary toxicity.

RESULTS:

Nonproductive cough, dyspnea, and fever appeared within the 10th chemotherapy cycle. Chest radiographs showed interstitial disease in each case, accompanied by a restrictive pattern by pulmonary-function testing. Lung biopsies were performed on two patients showing a pattern of interstitial inflammation. Discontinuing FUdR and instituting steroidal therapy invariably improved symptoms, as was evident by chest radiographs and pulmonary function tests. In one patient, resuming FUdR treatment resulted in a recurrence of the respiratory symptoms, which was controlled with an increased steroidal dose. All three patients required low dose steroids to maintain their baseline respiratory functions.

CONCLUSIONS:

2'-deoxy-5-fluorouridine-related lung toxicity is an uncommon event and occurs late in the treatment course. It is rapidly symptomatic and responds readily to steroidal therapy.
