Abstract

Background Due to its very aggressive nature and low survival chances, the metastasized urothelium carcinoma poses a challenge in regard to therapy. The gold-standard chemotherapy is platinum based. The therapy options are considered controversial, including new systemic therapies. In this respect, surgical therapies, as already established for pulmonary metastases of other tumor entities play an increasingly important role. The consumption of nicotine is a risk factor not only for urothelium carcinoma but also for a pulmonary carcinoma. Thus, we examined the frequency of a second carcinoma in this cohort.

Methods We retrospectively examined patients who had a differential diagnosis of pulmonary metastases, as well as those patients who underwent a surgery due to pulmonary metastases of a urothelium carcinoma between 1999 and 2015.

Results A total of 139 patients came to our clinic with the differential diagnosis of pulmonary metastases of a urothelium carcinoma. The most common diagnosis was pulmonary carcinoma (53%). Thirty-one patients underwent surgeries due to pulmonary metastases of a urothelium carcinoma. The median survival was 53 months and the 5-year survival was 51%. With the univariate analysis, only the relapse-free interval of more than 10 months was statistically significant (p < 0.001).

Conclusion There is a high coincidence of urothelial carcinoma and lung carcinoma. A histological confirmation should be endeavored. Selected patients undergoing a pulmonary metastasis resection have a survival advantage during the multimodal treatment of pulmonary metastasized urothelial carcinomas. For a definitive recommendation, randomized trials including a uniform multimodal therapy regimen and higher numbers of patients are necessary.
