Non-Hodgkin’s lymphoma is a malignant tumour that can be subdivided into many types depending on the origin of the lymphocytes and the type of pathology, with varying degrees of severity and prognosis.
Inert B-cell lymphomas, such as follicular lymphoma (grade 1-2), marginal zone B-cell lymphoma and chronic lymphocytic leukaemia/small lymphocytic lymphoma, progress slowly and have a long median survival.
In contrast, aggressive T-cell lymphomas, such as advanced NK/T-cell lymphomas tend to progress more rapidly, are prone to combined phagocytic syndromes and are among those with a poorer prognosis.
