Non-Hodgkin's lymphoma

Non-hodgkinrsquo; s lymphoma (NHL) is a major type of malignant lymphoma. The proportion of non-Hodgkin's lymphoma in our country is much higher than that of Hodgkin's disease (HD ). In recent years, the incidence of NHL has increased in many countries. The pathological type, clinical manifestations and treatment of NHL are far more complicated than HD. From the available data, NHL is a very heterogeneous group of diseases with different causes, pathologies, clinical manifestations and treatments. So far, the overall cure rate is also lower than HD. The duration varies from asymptomatic and early tolerable to rapid death. In some types of NHL, leukemia-like changes occur in 50% of children and about 20% of adult patients.
