There is no clinical statement about how long kidney cancer can last when blood in urine has already appeared, and it needs to be judged according to the risk factors of the disease and cannot be generalized. Usually, the typical symptoms of kidney cancer patients are hematuria, lumbar pain and abdominal mass, which is also known as the triad of kidney cancer. However, it is not possible to judge the patient’s condition and prognosis by the symptoms. Generally, when patients have the triad signs of kidney cancer, about 60% of them have already reached the clinical T3 stage, which is in the advanced stage, and most of the patients have a poor prognosis. The prognosis of patients should be judged according to the risk factors. If the patients have 3~6 factors of diagnosis to treatment interval less than 1 year, serum calcium greater than the upper limit of symptom index, hemoglobin less than the lower limit of normal index, cardinal physical status less than 80, and lactate dehydrogenase greater than 1.5 times of the upper limit of normal index, then they will be considered to be high-risk and have a shorter survival time, and 1~2 risk factors belong to intermediate-risk and have a relatively longer survival time. Relatively longer. It is suggested that when kidney cancer patients have symptoms of blood in urine, they should take systematic treatment under doctors’ guidance in time to avoid delay and prolong their life time as much as possible.
