They both play a part in deciding on a treatment plan and a prognosis. The following are prognostic and predictive factors for Wilms tumour. Type of tumour. The type of Wilms tumour is an important prognostic factor. Tumours with favourable histology have a better prognosis than those with anaplastic (unfavourable) histology . The overall prognosis of Wilms Tumor is usually quite positive with more than 80% of all children diagnosed expecting to survive the disease long-term. With a timely. Wilms tumor is the most common renal malignancy in children [ 1 ]. Five-year overall survival rates have dramatically improved with multimodal therapy and now approach 90 percent. The treatment and outcome of Wilms tumor will be reviewed here. The epidemiology, presentation, diagnosis, and staging of Wilms tumor are discussed separately There are diagnostic and therapeutic difficulties in that older age group. The preoperative diagnosis of nephroblastoma in adults is difficult because there are no specific radiographic findings that allow to distinguished it from the more common adult renal tumors. Histopathologically, there is no difference between adult and childhood Wilms' tumor Wilms' tumor is a rare kidney cancer that primarily affects children. Also known as nephroblastoma, it's the most common cancer of the kidneys in children. Wilms' tumor most often affects children ages 3 to 4 and becomes much less common after age 5
Wilms tumors can grow quite large before any symptoms develop. When they do appear, symptoms may be similar to those of other diseases. One of the earliest symptoms that may be noticed is a large lump or hard mass in your child's belly (abdomen).

Blood and urine tests. These lab tests can't detect Wilms' tumor, but they can indicate how well the kidneys are working and uncover certain kidney problems or low blood counts. Imaging tests Most Wilms tumors are found before they have spread (metastasized) to other organs. Wilms tumor may spread to the lungs, liver, bone, brain, or nearby lymph nodes. Symptoms include a lump in the abdomen, blood in the urine, and a fever for no reason. Tests that examine the kidney and blood are used to find the tumor
Wilms' tumor, also known as nephroblastoma, is a cancer of the kidneys that typically occurs in children, rarely in adults. It is named after Max Wilms, the German surgeon who first described it. Approximately 650 cases are diagnosed in the U.S. annually. The majority of cases occur in children with no associated genetic syndromes; however, a minority of children with Wilms' tumor have a congenital abnormality. It is highly responsive to treatment, with about 9/10 children being cured Tests for Wilms Tumors Stages and Outlook (Prognosis) After a cancer diagnosis, staging provides important information about the extent of cancer in the body and anticipated response to treatment Treatment and prognosis Unilateral Wilms tumors are, usually, treated by a combination of nephrectomy and chemotherapy. Occasionally chemotherapy can be administered prior to surgery to downstage the tumor 1. This is especially useful when tumors are bilateral

Doctors often use survival rates while discussing the prognosis of patients. This is a standard norm which displays the percentage of patients with similar disease stage still surviving after a definite time period from the day of diagnosis Prognosis and Survival The prognosis (chance of recovery) for children with Wilms tumor is generally very good. Currently, the great majority of children with Wilms tumor are cured. The overall five-year survival rate for children with Wilms tumor is approximately 90% Wilms' tumor (WT) is the most common renal malignant tumor of childhood. Metastatic WT has a worse prognosis than localized disease. This study aims to assess the clinical outcome and different prognostic factors that influence treatment outcome of pediatric metastatic WT cases treated at National Cancer Institute (NCI), Egypt, between January 2008 and December 2015

Prognosis: Wilms' tumor can be classified into favorable and anaplastic histology groups for prognostic purposes. Favorable histology group does not have anaplastic cells in the tumor.

On the other hand, anaplastic histology group indicates either focal or diffused structures An important part of diagnosing Wilms tumor involves staging and classifying the disease, which will help your child's doctor determine treatment options and prognosis. Wilms tumor staging is the process of determining whether the cancer has spread and, if so, how far. Kidney tumors are typically categorized into five stages
The paper reviews the prognosis and the program of treatment for Wilms' tumor. Without therapy the disease is invariably fatal. Prognosis in treated cases is influenced by the type and the method of treatment as well as by the age of the patients and the anatomical extent of the disease. The overall survival is around 25 percent. For small and incapsulated tumors in patients of less than 18. Objective . This study is aimed at constructing and verifying nomograms that forecast overall survival (OS) and cancer-specific survival (CSS) of children with Wilms' tumor (WT). Patients and methods . Clinical information of 1613 WT patients who were under 18 years old between 1988 and 2010 was collected from the Surveillance, Epidemiology, and End Results (SEER) database This tumor is also known as Wilms tumor, being named after a German doctor who wrote one of the first medical articles on it, Max Wilms, in 1899. Wilms' tumors are more common in children under 5 years of age and rarely appear in older children or adults The prognosis for patients with Wilms' tumor is quite good, compared to the prognosis for most types of cancer. One German study reported the overall five-year survival rate to be 89.5%. The patients who have the best prognosis are usually those who have a small-sized tumor, a favorable cell type, are young (especially under two years old), and. A second Wilms tumor locus, WT2, maps to an imprinted region of chromosome 11p15.5, which, when it is a germline mutation, causes Beckwith-Wiedemann syndrome. About 3% of children with Wilms tumors have germline epigenetic or genetic changes at the 11p15.5 growth regulatory locus without any clinical manifestations of overgrowth Wilms' tumour staging and grading are used to give an idea about the prognosis. Advanced staging, diffuse anaplasia, predominant blastemal elements and lymph node invasion are indicators of poor prognosis. In spite of using the previously mentioned parameters, some tumours which were considered of low risk did not respond to therapy and.
