The expanded life span of such patients increases the overall risk for developing cancer, which is now estimated at 4-25% . The type of malignancy depends on the primary immunodeficiency, the age of the patient and possible viral infection, suggesting that different pathogenetic mechanisms are implicated in each case. Non-Hodgkin's lymphomas predominate, accounting for 60% of cases. The PIDs known to be associated with increased incidence of malignancy are: common variable immunodeficiency, IgA deficiency and DNA repair disorders. During recent years other types have also been included, such as severe combined immunodeficiency (SCID) and Wiskott Aldrich syndrome (WAS).
