We treated 6 patients with renal collecting duct carcinoma (CDC) in our hospital from December 2004 to December 2011. We compared clinico-pathological findings among all patients. The median age was 58 years (range, 37-77 years). Hematuria, back pain, and fatigue were observed in 5 patients with CDC. Five patients were pathologically diagnosed by radical nephrectomy while a patient was diagnosed by percutaneous renal biopsy without radical nephrectomy. Lymph node metastasis and distant metastasis were observed at diagnosis in 3 and 2 patients, respectively. Five of the 6 patients received systemic therapy after surgery, cytokine therapy in 2 patients, systemic chemotherapy in a patient, and molecular-targeting therapy in 2 patients, respectively. The median overall survival was 15 months (range, 1-44 months). Overall, the 1- and 3-year survival rates were 67 and 33%, respectively. Most of the patients had symptomatic advanced disease at diagnosis. Even though nephrectomy was performed, systemic treatment was not effective in such patients.
