Kidney failure patients who have cancer are generally able to be immunotherapy, but if kidney failure patients have poor basic immune function, or suffer from autoimmune disease, hepatitis and so on, immunotherapy should be used cautiously, and it is specifically recommended to consult with doctors. 1. Poor basic immune function: Cancer immunotherapy refers to the method of artificially enhancing the body’s immune function against tumors when the body’s immunity is in a low state, so as to achieve the therapeutic purpose. Since some patients have poor basic immune function and insufficient immune cells in their body, even after immunotherapy, it usually cannot achieve the therapeutic effect. Therefore, this kind of renal failure patients need to be cautious. 2. Autoimmune diseases: If renal failure patients have autoimmune diseases such as systemic vasculitis, rheumatoid arthritis, systemic lupus erythematosus, etc., immunotherapy may aggravate these diseases, therefore, caution is needed. 3. Hepatitis: It is a liver disease caused by autoimmune, bacterial, viral and other factors. Currently, immunotherapy has not gained efficacy on hepatitis, if patients with renal failure suffering from hepatitis receive immunotherapy, hepatitis may recur during the period, which may lead to liver failure, so immunotherapy should be used with caution. If the above factors exist, immunotherapy should be used with caution, and it is recommended that the choice be made under the guidance of a doctor.
