Purpose: Although rarely curative, chemotherapy remains the mainstay of treatment for metastatic urothelial cancer. The role of surgery for metastatic disease is not well established for urothelial cancer, but is sometimes undertaken in the face of persistent or recurrent disease that can be surgically resected.
Materials and methods: We identified 31 patients with metastatic urothelial cancer undergoing metastasectomy with the intent of rendering them free of disease. All gross disease was completely resected in 30 patients (97%). The most frequently resected location was lung in 24 cases (77%), followed by distant lymph nodes in 4 (13%), brain in 2 (7%) and a subcutaneous metastasis in 1 (3%).
Results: Median survival from diagnosis of metastases and from time of metastasectomy was 31 and 23 months, respectively. The 5-year survival from metastasectomy was 33%. Median time to progression following metastasectomy was 7 months. Five patients were alive and free of disease for more than 3 years after metastasectomy.
Conclusions: The results in this highly selected cohort, with 33% alive at 5 years after metastasectomy, suggest that resection of metastatic disease is feasible and may contribute to long-term disease control especially when integrated with chemotherapy. Further prospective studies should be undertaken to better characterize the selection criteria and benefit from this intervention.
