There is no clear data indicating how many years patients with high-grade invasive uroepithelial carcinoma can live. Generally, patients can live for 1 to 5 years, but due to the variability of individual conditions, it is not possible to make a generalization. Invasive uroepithelial carcinoma high-grade belongs to the more serious type of uroepithelial carcinoma, which has poorer prognosis and higher mortality rate. If patients with high-grade invasive uroepithelial carcinoma are found in time and actively take treatment measures, the survival rate can reach about 5 years, and some patients can live longer. However, if patients with high-grade invasive uroepithelial carcinoma are detected late and the area of invasion into surrounding tissues is large, the prognosis is relatively poor, and the survival time is around 1 year, which is impossible to make a generalization. Once the disease is diagnosed, surgical treatment, such as radical resection, lymph node dissection, etc., should be actively adopted, and at the same time, integrated treatment with radiotherapy, chemotherapy, etc., can help to prolong the life time and improve the quality of survival of patients. Once diagnosed with high-grade invasive uroepithelial carcinoma, patients should go to regular hospitals and actively take relevant treatment measures.
