INTRODUCTION: Splenic marginal zone lymphoma (SMZL) is a rare low-malignant Non-Hodgkin lymphoma (NHL), in which immune mediated paraneoplastic phenomena such as autoimmune hemolytic anemia (AIHA), autoimmune thrombocytopenia (ITP) and C1 esterase inhibitor deficiency are relatively common.
MATERIALS AND METHODS: We performed a multicenter retrospective study in 70 patients on the prevalence and clinical features of antiphospholipid antibodies (aPLA) in SMZL.
RESULTS AND CONCLUSIONS: Nine patients (13%) had the diagnosis of a lupus anticoagulant (LA). The occurrence of venous thromboembolic events was significantly higher in LA positive patients compared to LA negative patients (4/9 [44%] vs 5/61 [8%], p = 0.002), especially within 12 months after splenectomy (3/6 [50%] vs 2/28 [7%], p = 0.007). None of the patients with LA had a persistent complete remission of LA after splenectomy, but complete remission of LA was achieved in 2/2 patients after rituximab-bendamustine immuno-chemotherapy. In conclusion, our data show a relatively high prevalence of aPLA in SMZL and an increased risk of postsplenectomy thrombosis in these patients. The fact that rituximab-bendamustine was effective for eradicating LA may be considered as an argument for using immuno-chemotherapy as first line therapy in SMZL patients with LA.
