Long-term remission in a patient with metastatic collecting duct carcinoma treated with taxol/carboplatin and surgery

Abstract

Collecting duct carcinoma of the kidney is a rare and aggressive neoplasm of the distal collecting tubules for which there is no established therapy. We describe a young woman with metastatic collecting duct carcinoma who responded to Taxol/carboplatin chemotherapy with an 80% reduction in her tumor burden, including complete regression of lymph node metastases and significant shrinkage of a renal mass. She was rendered free of disease through nephrectomy and has been without a recurrence for 20 months. This suggests that Taxol/carboplatin chemotherapy and surgery should be considered for the treatment of metastatic collecting duct carcinoma.
