چکیده

The etiology of non-Hodgkin's lymphomas (NHL) remains a controversial matter, but, in the last few years, considerable evidence suggests that aberrations of the immune system and viruses may act as etiologic agents, in at least some cases of NHL. In fact, patients with primary immuno-deficiencies, or those suffering from diseases characterized by autoimmune dysfunction, show an increased risk for the development of NHL. Several viruses have been identified as possible etiologic agents for NHL; one of the best studied is the Epstein-Barr virus, which was detected in cultures of tumor cells from patients with Burkitt's lymphoma. The pathogenetic potential of this virus is illustrated by its association with an increasing number of malignant diseases. In addition, the human T-cell lymphotropic virus family (HTLV), was also recognized as possible etiologic agents for several lymphomas, such as cutaneous T-cell lymphoma and T-cell leukemia-lymphoma syndrome (HTLV-I), and T-cell hairy cell leukemia (HTLV-II). Recently, the presence of hepatitis C virus infection has also been recognized in several hematological malignancies such as mixed cryoglobulinemia, low-grade malignant lymphomas and Waldenström's disease. The possible etiopathogenetic role of this virus in non-Hodgkin's lymphomas is discussed on the basis of molecular, clinical, and epidemiological considerations.
