Prognostic factors in lymphomas: non-Hodgkin's lymphomas and Hodgkin's lymphoma

Abstract

Lymphoid tumour pathology, which includes both non-Hodgkin's lymphomas and Hodgkin's lymphoma, represents a very heterogeneous group of cancers that have in common their origin in the proliferation of lymphoid cells arrested in different stages of their maturative development. Thus, diseases that are very different from the histological, clinical and evolutionary points of view are included in the lymphomas, which require treatments that depend to a great extent on the aggressiveness of the lymphoma and must be adjusted to the risk shown by each specific patient. To evaluate this risk it is essential to know the approximate prognosis of the patients, which depend on a series of initial and evolutionary variables that are related to the type of response to treatment and with survival.
