Cystic renal cancer (CRCC) is a special type of renal cancer, which usually has a better prognosis, with a 5-year overall survival rate of about 88.3% and a 5-year tumor-specific survival rate of about 95.2%. Cystic renal carcinoma (CRCC) is a rare subtype of renal cancer, which originates from renal tubular epithelium, and is usually referred to as renal carcinoma with cystic or mixed cystic-solid changes in imaging. CRCC accounts for 4%-15% of renal cell carcinoma, with a male-to-female ratio of 2.4:1, and the age of onset is 40-83 years old, which is a relatively low incidence. For early detection, early diagnosis and early treatment of cystic renal cancer, the prognosis is good, the overall five-year survival rate of patients is about 88.3%, and the five-year tumor-specific survival rate is about 95.2%. The later the clinical stage, the lower the cure rate and the higher the recurrence rate. Therefore, once cystic kidney cancer is detected, patients need to treat it in time to improve the chance of cure and prolong the survival period as much as possible. Cystic kidney cancer is also a kind of serious tumor disease, which needs to be treated by surgery as soon as possible. However, for patients with advanced stage, comprehensive treatment mainly based on internal medicine should be adopted to prolong the survival period as much as possible. Of course, besides treatment, patients also need to take good care of their daily life to help their condition recover.
