Pulmonary fibrosis is a serious side effect of nitrosourea therapy, occurring most frequently in patients treated with BCNU. Pulmonary fibrosis developed in a 63 year-old male patient while being treated with adjuvant methyl-CCNU for rectal carcinoma. This toxicity is rare with methyl-CCNU, having only been reported once previously. The case of methyl-CCNU-induced pulmonary fibrosis reported here occurred at a much lower total dose than the first reported case (604 mg/m2 vs. 2,733 mg/m2). Details of the case history, including radiographic and pathologic findings, are presented.

Two patients treated for chronic myeloid leukemia with high doses of CCNU (1100 mg/m2 and 1240 mg/m2, respectively) developed a fatal pulmonary fibrosis. This side effect has never been reported for this nitrosourea but only for BCNU and methyl-CCNU. The responsibility of CCNU in the pathogenesis of pulmonary fibrosis seems very likely. The possibility that the underlying disease or other chemotherapeutic agents may increase the risk of pulmonary toxicity can, however, be discussed. In addition, 13 other adults treated for chronic myeloid leukemia with various doses of CCNU were reviewed. No respiratory symptoms appeared in the ten patients who were given less than 950 mg/m2. Three patients who received more than 1100 mg/m2 developed pulmonary symptoms with the same clinical and radiologic pattern as in the two cases with pathologic documents, and two of them died from acute respiratory failure. Although lung specimens were lacking from these three patients, it is suggested that the pulmonary toxicity of CCNU may be dose-related.
