Tumor en el cerebro tiene cura1/15/2024 ![]() Stage I : The tumor is only in the kidney, and the capsule around the kidney is not broken. It is the major staging system currently used for Wilms tumor. The following staging system is recommended by the Renal Dis- ease Committee of the Children’s Oncology Group (COG). Staging for Wilms tumor is determined by the surgeon when the tumor is removed and by X rays and scans that look for metastatic disease. The method of treatment proposed for your child will depend upon the stage of the disease at the time of diagnosis. N WHAT IS STAGING? Staging is the process of determining the extent of the disease at the time of diagnosis. Wilms tumors sometimes spread to the liver, other kidney, brain, or bones. The most common site of metastasis is the lungs. Wilms tumors may metastasize, or spread, through the blood system or the lymphatic system (tissues and cells that help to fight infection). N WHAT IS METASTASIS? Metastasis refers to the spread of cancer from its original location (primary site) to other parts of the body. If your child’s doctor suspects that your child has an inherited type of tumor, examination of family members and genetic counseling are available. The presence of Wilms tumor in other family members or the presence of intellectual disabilities or other birth defects in the child is another indication that the child may be genetically predisposed to developing Wilms tumor. It appears that children who have the disease in both kidneys and who are younger at the time of diagnosis are more likely to have a genetic predisposition to develop Wilms tumor. ![]() Studies have shown that about 2% of all Wilms tumors are inherited (one or more family members with a history of the disease). n IS WILMS TUMOR INHERITED? Cancer may be caused by abnormalities in the genes, but only some forms are inherited. It is less common in older children and rare in adults. The most common age at diagnosis is 3–4 years. Most children (78%) diagnosed with Wilms tumor are between 1 and 5 years of age. It is slightly more common among African-American children and females than among Caucasian children. Approximately 500 cases of Wilms tumor are diagnosed each year in the United States. n WHO GETS DIAGNOSED WITH WILMS TUMOR? Wilms tumor accounts for 5% of all childhood cancers. Cancer is not caused by anything the child ate or didn’t eat (such as vegetables or vitamins). No behaviors or lifestyle habits, including those practiced during pregnancy, have been associated with the development of Wilms tumor. We do know that it is not contagious or genetic, so it cannot be passed from person to person. N WHAT CAUSES WILMS TUMOR? The cause of Wilms tumor isn’t known at this time. One out of every four children diagnosed with Wilms tumor also has high blood pressure. Some other general signs and symptoms are belly pain, tiredness, blood in the urine (usually found only by a urine test), and occasionally fever. Usually a caregiver notices the child’s enlarged belly or feels a mass in the belly while bathing or dressing the child. N WHAT ARE SOME OF THE SIGNS AND SYMPTOMS OF WILMS TUMOR? The most common sign of Wilms tumor is an enlarged or bloated belly in an otherwise healthy-looking child. Rhabdoid tumors and clear-cell sarcomas of the kidney are occasionally found in children and are more difficult to treat than Wilms tumor. Not all of the kidney tumors found in children are Wilms tumors. In rare cases, Wilms tumor can occur outside of the kidney. Wilms tumor can arise anywhere within the kidney. It is the most common childhood cancer of the kidneys. n WHAT IS WILMS TUMOR? Wilms tumor is a cancer that develops from kidney cells.Users may copy and distribute this material in unadapted form only, for noncommercial use, and with attribution given to APHON.Ĭopyright © 2021 Association of Pediatric Hematology/Oncology Nurses 8735 W.
