Whether or not a 5-6 course of chemotherapy for lymphoma can be cured is related to the physical fitness of the patient, the type and stage of the lymphoma. Lymphoma is mainly divided into Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. 1. Hodgkin’s lymphoma: it is generally a curable malignant tumor. For stage I and II lymphoma, about 2~4 courses of treatment are needed, and if it is stage III~IV, 6~8 courses of treatment or even longer may be needed, and everyone’s physique is different, and their physical condition is different, so doctors need to adjust the treatment plan according to the patient’s condition. 2. Non-Hodgkin’s lymphoma: due to the higher degree of malignancy, patients with stage Ⅰ ~ Ⅲ may need about 8 courses of treatment according to their own conditions; patients with stage Ⅳ have higher degree of malignancy, and the specific treatment is also according to their own conditions, and the high-risk cases may also choose intensive combined treatment. Whether lymphoma can be cured by 5-6 courses of chemotherapy should be judged according to the patient’s condition and treated under the doctor’s guidance.
