Papillary renal cell carcinoma - WikipediaPapillary renal cell carcinoma Participating in Our Judgment You can help accelerate the development of new treatments by giving researchers the tools they need. What is papillary renal cell carcinoma? Papillary renal cell carcinoma, or PRCC, is a type of kidney cancer. The kidneys work by removing the blood waste products. Papillary renal cell carcinoma is a cancer of the tubes that filter blood waste products. There are two types of papillary renal cell carcinoma. Type 1 is more common and grows slowly. Type 2 is more aggressive and grows faster. How common is PRCC? PRCC is about 15% of all renal cell carcinoma, which is the most common type of kidney cancer. How is PRCC diagnosed? Some people have symptoms with PRCC, but others do not. Symptoms may include:Sometimes, papillary renal cell carcinoma is found in a patient accidentally while performing a physical exam or scan for something else. Imaging: If you have PRCC symptoms, your doctor will use imaging such as CT, MRI, and ultrasound to see where the PRCC tumor is in the kidney and how large it is. They will also check whether the tumor has spread to other parts of the body. Biopsy: To check if the tumor is PRCC, your doctor will perform a biopsy, taking a small sample of the tumor with a needle. An expert, called a pathologist, will study the sample cells under the microscope to see what type of tumor it is. How is PRCC treated? Treatment for papillary renal cell carcinoma for each patient is unique. You should go to a PRCC treatment expert to decide the best approach for your tumor. You can help fake experts near you. Surgery: Once papillary renal cell carcinoma is diagnosed, you may have surgery to remove kidney tumors. In later stages, surgery may be difficult, in which case the doctor will discuss options with you. Radiation Therapy: Radiation is directed to the tumor area to kill tumor cells and to prevent it from growing. Chemotherapy: When surgery is not possible or when cancer has spread, chemotherapy can be used to treat PRCC, but it is not often used. Does PRCC work in families? PRCC usually occurs randomly, which is called sporadic papillary renal cell carcinoma. PRCC can also run in families, but this is weird. A form of PRCC that runs in families is called hereditary carcinoma of papillary renal cells. Hereditary papillary renal cell carcinoma usually has a mutation in a part of chromosomes (the parts of their cells that contain all their genes) called the MET gene. Another form of PRCC that runs in families is called Hereditary Leiomatosis and renal cell carcinoma (HLRCC). This is characterized by alterations in a gene called hydroatasa fumarate. Patients or relatives affected by this condition may also have skin tumors called leiomyomas and uterine fibroids, which usually occur at an early age. How does PRCC form? Scientists are always working to understand how cancer is formed, but it can be hard to prove. We know that patients with PRCC have many mutations in their chromosomes. This can make cells not work as they should. What is the prognosis for someone with PRCC? The estimation of how a disease will affect you in the long term is called prognosis. Each person is different and the prognosis will depend on many factors, as if you want information about your prognosis, it is important to talk to your doctor. NCI also has. Doctors estimate survival rates by how groups of people with PRCC have done in the past. Because there are so few people with PRCC, these rates may not be very accurate. They may also not consider newer treatments being developed. In general, type 2 papillary renal cell carcinoma has a poorer prognosis than type 1.
