Collecting duct carcinoma
Collecting Duct Carcinoma
Collecting duct carcinoma (kəˈlɛktɪŋ dʌkt kɑːrsɪˈnoʊmə), also known as Bellini duct carcinoma, is a rare type of renal cell carcinoma that originates from the collecting ducts of the kidney. The etymology of the term comes from its discovery in the collecting ducts, which are part of the renal system, and the term "carcinoma", which is derived from the Greek words "karkinos" (crab) and "oma" (tumor), indicating a cancerous growth.
Overview
Collecting duct carcinoma is a subtype of renal cell carcinoma, which is a group of cancers that start in the renal tubule of the kidney. It is named after the collecting ducts, a series of tubules in the kidney that collect urine from the nephrons and transport it to the renal pelvis.
Symptoms
The symptoms of collecting duct carcinoma are similar to other types of renal cell carcinoma and may include hematuria (blood in the urine), flank pain, and a palpable abdominal mass. However, due to its rarity and aggressive nature, collecting duct carcinoma is often diagnosed at a later stage compared to other renal cell carcinomas.
Diagnosis
Diagnosis of collecting duct carcinoma is typically made through imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI), and confirmed with a biopsy of the kidney tissue.
Treatment
Treatment options for collecting duct carcinoma include surgery, chemotherapy, and radiation therapy. The choice of treatment depends on the stage of the disease, the patient's overall health, and other factors.
Prognosis
The prognosis for collecting duct carcinoma is generally poor, as the disease is often advanced at the time of diagnosis. However, early detection and treatment can improve survival rates.
