【 摘 要 】

The development of malignant lymphomas, generally of the non-Hodgkin type (NHL), and with a preference to diffuse large cell B lymphomas (DLCBL), in systemic lupus erythematosus (SLE), has been analysed in an exhaustive recent literature. The combination of germline and somatic mutations, persistent immune overstimulation and the impairment of immune surveillance facilitated by immunosuppressive drugs, is thought to be at the origin of the increased lymphoma genesis. However the treatment and course of such affected patients is less known, and prognosis is generally estimated as poor. Out of 258 patients with complete/incomplete lupus and secondary antiphospholipid syndrome (APS) seen and treated at the institutional Day Hospital between 1982 and 2009, 6 developed lymphomas (4 DLCBL, 1 Hodgkin`s and 1 indolent lymphocytic lymphoma). The first 5 patients were treated with high dose chemotherapy (HDCT) and achieved complete remissions (CR) with a follow-up comprised between 13 and 172 months. One patient relapsed of lymphoma and died 15 months following CR, with persistent lupus serology. One patient achieved complete remission (CR) of both diseases. In the other 3 lupus serology, Antinuclear and antiphospholipid antibodies (ANA, aPL) persisted, with occasional lupus flares and vascular complications. While eradication of the last cancer stem cell is tantamount to cure in neoplastic disease, persistent autoantigenic overstimulation may contribute to the refractoriness of autoimmunity. The implications of these results for the increasing utilisation of haematopoietic stem cell transplantation for severe autoimmune diseases (SADS), with lupus as a paradigm, are discussed.
