Abstract
A 66-year-old man with a history of multiple transurethral resections for recurrent bladder tumors, staged as Ta according to the International Union Against Cancer staging guidelines, presented with a complaint of dry cough. A round nodule with a diameter of 7.5 cm was detected in the lung by chest computed tomography, and a video-assisted thoracoscopic lobectomy was performed. Pulmonary metastasis of recurrent bladder cancer was diagnosed by immunohistochemistry staining for the urothelium-specific protein uroplakin Ia. Subsequently, 2 cycles of systemic chemotherapy were administered. Two and a half years after treatment, no recurrence of pulmonary lesions has been detected. A combination of complete resection of pulmonary lesions and systemic chemotherapy may result in a good prognosis for patients with non-muscle-invasive bladder cancer.
