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.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
