The survival time of patients with advanced kidney cancer after spreading is determined by patients’ conditions, treatments and patients’ physique, etc. For patients with high malignant degree, untimely or unstandardized treatments and poor physique, they can survive for several months, while those with relatively low malignant degree, timely and standardized treatments and patients with good physique can survive for 1 to 2 years or even longer. 1. Patient’s condition: it is mainly decided according to the typing of renal cancer. For clear cell carcinoma and other types of renal cancer, the degree of malignancy is relatively low and the prognosis is relatively good, while collecting duct carcinoma has a higher degree of malignancy and a poorer prognosis. 2. Treatment: For patients with untimely and non-standardized treatment, their condition develops relatively fast, whereas after timely and effective treatment, their condition develops slowly, or even gets effective control, and they have longer survival time, such as surgical treatment, targeted drug treatment (sorafenib, etc.), and so on. 3. Patient’s physical condition: patients with better physical condition have stronger resistance to the disease and longer survival time, while patients with poorer physical condition have weaker resistance to the disease and shorter survival time. The specific situation suggests that patients go to the hospital for examination, according to the severity of the patient’s condition to give the appropriate treatment, the survival time varies from person to person, can not be completely determined.
