Wilms’ Tumor Staging Wilms’ tumors are classified as favorable and unfavorable. These distinctions tell us how challenging the tumor may be to treat. About 90 percent of children with Wilms’ tumor have favorable tumors. Wilms' tumor staging is largely anatomical and relates to the invasion and spread of the tumor. Where there is invasion or metastasizes, prognosis is poorer. Wilms tumor, is one of the more common childhood malignancies.

Where there is invasion or metastasises, prognosis is poorer. Wilms tumour, is one of the more common childhood malignancies. Wilms tumour: prognostic factors, staging, therapy and late effects Wilms tumour is the most common malignant renal tumour in children. Dramatic improvements in survival have occurred as the result of advances in anaesthetic and surgical management, irradiation and chemotherapy. Deposits of tumor (tumor implants) are found along the lining of the abdominal cavity About 20% of all Wilms tumors are stage III. Stage IV The cancer has spread through the bloodstream to other organs far away from the kidneys, such as the lungs, liver, or bone, or to lymph nodes.

With modern surgery, chemotherapy, and radiation therapy approaches, the overall survival rate for patients with Wilms tumor has reached 90%. Remarkably, the increase in survival has been achieved with a reduction in therapy for most Background Wilms tumor (WT) is the most common renal malignant tumor in children.

[17] [18] According to the extent of tumor tissue at the time of initial diagnosis, five stages are considered. Wilms tumor, mixed type, intermediate risk tumor, stage III (due to viable and nonviable lymph node metastases) Comment: Tumor shows chemotherapy induced changes occupying 40% of the mass. The viable tumor consists of blastemal (20%), epithelial (50%) and stromal (30%) elements, with no evidence of anaplasia. Wilms tumor (WT) is the second commonest childhood solid tumor and accounts for more than 90% of childhood renal tumors. Clinical presentation Most children present with a large asymptomatic abdominal mass, and rarely exhibit symptoms secondary to tumor rupture or extensive pulmonary metastasis.
