    Author: Jia N, Tang FL.
    Journal: Zhonghua Yi Xue Za Zhi; 2009 Oct 27; 89(39):2786-8. PubMed ID: 20137605.
    Abstract:
    OBJECTIVE: To characterize the clinical patterns of expression, laboratory serologic parameters and lymphomatous histological characteristics in patients with primary Sjögren's syndrome (pSS) who subsequently developed non-Hodgkin's lymphoma (NHL). METHODS: The authors analyzed 9 pSS patients (8 females, 1 male) who developed NHL. Five patients had received glucocorticoids, four of whom had received at least one immunosuppressive drugs (methotrexate, glucosidorum tripterygll totorum, cyclophosphamide and imuran). A protocol form was used to record the main characteristics of pSS and NHL. RESULTS: Eight patients fulfilled the American-European Consensus Criteria (AECC). The main SS manifestations were painless parotid enlargement (n = 7), six of whom were unilateral; the main immunologic features were positive rheumatoid factor (RF) in all examined patients and hyperimmunoglobulinemia (n = 7). The main manifestations of NHL were splenomegaly (n = 7) and lymphadenopathy (n = 5). The main histological subtypes were mucosa-associated lymphoid tissue (MALT) lymphoma (n = 4) and diffuse large B cell lymphoma (n = 2). None of the patients with MALT lymphoma had a nodal primary location. Eight patients had an extranodal primary location, most frequently in salivary gland (n = 4) and lung (n = 4). CONCLUSION: Patients with pSS and NHL are clinically characterized by a high frequency of painless unilateral parotid enlargement, splenomegaly, lymphadenopathy, an immunologic pattern dominated by the presence of high-titer RF and hyperimmunoglobulinemia, a predominance of MALT lymphomas and an elevated frequency of primary extranodal involvement.
