BACKGROUND: Patients with idiopathic pulmonary fibrosis have an increased incidence of lung cancer. The purpose of this study was to determine the outcome of surgical treatment of lung cancer with idiopathic pulmonary fibrosis. METHODS: From January 1992 through December 2001, 64 patients who had simultaneous lung cancer and idiopathic pulmonary fibrosis were treated. Twenty-one (33%) of them underwent surgical resection of lung cancer, and their data were reviewed. RESULTS: There were 56 men and 8 women with an average age of 69 years (range, 43 to 85 years). In the surgical group, there were no early postoperative deaths, and nonfatal complications occurred in 2 patients (10%). Among the 14 patients with stage I cancer, a second primary lung cancer developed in 5 (36%). The causes of death in the surgical group were cancer related in 7 patients, exacerbation of idiopathic pulmonary fibrosis in 7, and other in 2. Five of the 7 patients who died of a cancer-related cause had development of a second primary lung cancer. The actuarial 2-year survival rate of the surgical group was 52% overall, 58% for patients with N0 or N1 disease and 25% for those with N2 disease (p = 0.05). CONCLUSIONS: The long-term results in one surgical group were poor partly because of the high incidence of a second primary lung cancer and partly because of the poor natural history of idiopathic pulmonary fibrosis. These patients require intensive surveillance even after curative resection of lung cancer.
