AIM: To develop algorithm of early diagnosis of extranodal lymphoma arising in patients with Sjorgen's disease (SD).
MATERIAL AND METHODS: SD diagnosis was made in 457 patients treated in Rheumatology Institute clinic in 1999-2004, 38 (8.3%) females aged 19-82 had lymphoproliferative diseases. MALT-lymphomas were diagnosed in 15 (42.2%) patients. All the patients have undergone morphological, immunomorphological investigations of the salivary glands, postoperative material was analysed in some patients. In addition, the following investigations were made: ultrasonography of the salivary glands, lymph nodes, viscera; scintigraphy; trephine biopsy of the bone marrow; myelograms; CT of the chest, abdomena and brain; tests for monoclonal immunoglobulins in the serum and light chains in urine; biopsy of the parotid gland. Clinical, morphological and immunophenotypical characteristics of MALT-lymphomas were assessed by WHO classification. Lymphoma stages were classified according to Ann Arbor.
RESULTS: Parotid glands were affected with MALT-lymphoma most frequently. Predominant were extranodal lymphomas of the parotid submandibular, minor salivary glands of the lip and lacrimal glands of stage I E-II E. Extranodal lymphoma with nodal lesion of stage IV occurred less frequently. Untreated long existing MALT-lymphomas of the parotid glands may transform into B-large cell lymphomas deteriorating SD prognosis. The presence of long-term (> 12 months) massive enlargement of parotid/submandibular salivary and lacrimal glands, massive infiltration, monoclonal immunoglobulins in blood serum and their light chains in the urine predict development of MALT-lymphoma in SD.
CONCLUSION: In SD, MALT-lymphomas develop primarily in target organs--salivary and lacrimal glands. SD patients with persistent enlargement of the parotid glands need biopsy for early detection of malignant lymphoproliferation.
