Purpose: To evaluate the prognostic impact of restrictive ventilatory impairment in patients who undergo pulmonary resection of metachronous second primary lung cancer.

Methods: The clinical characteristics and surgical outcomes of 70 patients with metachronous second primary lung cancer were analyzed.

Results: The surgical procedures consisted of wedge resection in 40 patients, segmentectomy in 17, lobectomy in 12, and completion pneumonectomy in one. Patients who underwent ipsilateral pulmonary resection developed more perioperative complications (p = 0.0339). Three-year and 5-year overall survival rates were 78.2% and 69.2%, respectively. In univariate analysis, sex, restrictive ventilatory impairment, and histology of second primary lung cancer were significantly poor prognostic factors (all p <0.05). Multivariate analysis identified restrictive ventilatory impairment to be an independent predictor of a poor prognosis (p = 0.0193). In the 22 patients who died, the cause of death was lung cancer in 11 and other diseases, including pneumonia and respiratory failure, in 11. Death from another disease was significantly more common in patients with restrictive ventilatory impairment (p = 0.0216).

Conclusion: Restrictive ventilatory impairment was an independent predictor of a poor prognosis in patients with a second primary lung cancer. Restrictive ventilatory impairment as a result of repeated thoracic surgery may increase the likelihood of death from another disease.
