If you have lymphoma and it is already at an advanced stage, the survival time varies from 1-3 months because the malignancy of lymphoma is relatively high and many patients are in the progressive or late stage at the time of diagnosis. The most effective treatment for this disease is systemic intravenous chemotherapy, which is so hard on the body that many patients have difficulty completing systematic intravenous chemotherapy. Patients with advanced disease may show significant anemia, hypoproteinemia, and metastases to multiple organs, and may also show significant wasting and progressive worsening of cachexia. In this case, if the patient’s economic condition allows, intravenous plasma supplementation or human albumin can be chosen to improve the patient’s nutritional status, which can prolong the patient’s life to a certain extent and improve the quality of life in the late stage.
