Abstract

Purpose: Collecting duct carcinoma is a rare type of renal cell carcinoma that affects younger patients, and is associated with aggressive regional and distant spread. The clinical and pathological features of 6 patients with collecting duct carcinoma treated at a single institution are described.

Materials and methods: There were 6 patients with collecting duct carcinoma included in the University of California School of Medicine, Los Angeles, Kidney Cancer Database. Demographic, clinical, pathological and survival data were gathered.

Results: Average patient age plus or minus standard deviation was 56 +/- 11 years, and 5 of 6 had TNM stage IV disease. The average survival of these patients was 11.5 months (range 7 to 17). There was 1 patient who had TNM stage I disease and survived without evidence of disease at 5 years. Transient response to chemotherapy was seen in 1 patient.

Conclusions: Collecting duct carcinoma is associated with poor prognosis. For the majority of patients surgical treatment will not result in a cure. Previously recommended chemotherapy and/or immunotherapy appears to have a limited role in treatment of this disease, and early detection may be the best method for prolonging patient survival.
