[Show abstract][Hide abstract] ABSTRACT: Collecting duct carcinoma of the kidney is a rare and aggressive neoplasm of the distal collecting tube, often metastatic at the time of the diagnosis, for which there is no established therapy. We herein describe the case of a 65-year-old man with a renal cancer with a particular immunohistochemical pattern and pathologic aspect. The lesion was diagnosed as a tumor borderline between a urothelial carcinoma with intraductal spreading and a collecting duct carcinoma with calyceal and pelvic spreading. The patient is disease-free 11 months after diagnosis, after radical surgery with adjuvant chemotherapy (carboplatin and gemcitabine) and radiotherapy of a local recurrence. Owing to the common embryologic origin of collecting duct and transitional urothelial cells, several authors have reported an association between collecting duct carcinoma and urothelial cancer. The literature is reviewed to evaluate drugs active against urothelial cancer (like ifosfamide, paclitaxel, carboplatin and gemcitabine). This field should be investigated in the future, in the framework of a neoadjuvant or adjuvant chemotherapy able to support radical surgery for local and advanced collecting duct carcinoma.
[Show abstract][Hide abstract] ABSTRACT: We present clinical and radiological findings in a case of collecting (Bellini) duct carcinoma (CDC). This is a rare and aggressive kidney cancer originating from the distal renal tubule. The patient underwent radical nephrectomy and the pathological report showed trabeculopapillary, partially solid adenocarcinoma infiltrating the renal capsule and sinus. Immunohistochemical, as well as mucinocarminic and PAS staining studies are necessary for diagnosis of CDC. Surprisingly, one year follow-up studies were negative for recurrent disease. Chromosomal findings are usually different from most often diagnosed clear cell renal cell cancers. Findings from the literature are briefly discussed.

[Show abstract][Hide abstract] ABSTRACT: 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.
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.
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.
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.
