Early stage nephroblastoma has a high cure rate. 1. Nephroblastoma is a common malignant tumor disease in the urinary tract of young children. The cause of nephroblastoma is unknown. Imaging examinations such as intravenous urography, B-mode ultrasound, CT or magnetic resonance can help to diagnose the disease and understand the spread of the disease, and the confirmation of the diagnosis depends on pathological examination. 2. Nephroblastoma is often treated with a combination of surgery, radiotherapy and chemotherapy. The disease is sensitive to radiotherapy, and adjuvant radiotherapy should be carried out for stage II, III and IV tumors. While chemotherapy plays an important role in controlling local recurrence and metastasis, commonly used drugs include actinomycin D, vincristine and doxorubicin. At present, after treatment, the 4-year survival rate of patients with stage I and II good tissue type of nephroblastoma has reached more than 90%. Therefore, if you feel unwell, please go to the hospital in time to improve the examination and make a clear diagnosis, so as not to delay the condition.
