Objective: To determine the clinical and laboratory predictors of lymp
homa development in primary Sjogren's syndrome (pSS). Methods: Seventy
-two patients with pSS were studied. Demographic data, clinical featur
es, serum gamma-globulin levels, autoantibodies, and HLA status were r
eviewed, For statistical analysis, Mann-Whitney U-test, Fisher's exact
test, logistic regression analysis, Kaplan-Meier method, and log-rank
tests were applied, Results:Five patients developed a distinct non-Ho
dgkin's lymphoma of mucosa-associated lymphoid tissue (MALT), A histor
y of swollen salivary glands, lymphadenopathy, and leg ulcers predicte
d lymphoma development. Conclusion: Patients with pSS are at increased
risk of lymphoma development and those who have the above risk factor
s must be carefully observed. Copyright (C) 1998 by W.B. Saunders Comp
