Title: Abstracts: Sjögren’s Disease – Basic & Clinical Science (1680–1685)
Session Type: Abstract Session
Session Time: 1:15PM-1:30PM
Background/Purpose: The association between Sjögren’s disease (SjD) and non-Hodgkin lymphoma (NHL) is well established, although reported standardized incidence ratios (SIRs) vary considerably across studies. In contrast, the risk of solid tumors in SjD remains controversial, with conflicting evidence in the literature. This study aimed to determine the SIRs for lymphoma and other malignancies (both hematologic and solid tumors) in patients with SjD, identify independent predictors of cancer development, and assess the impact of malignancies on overall mortality.
Methods: We conducted a prospective, multicenter observational study including 314 patients with SjD who met the 2002 American-European Consensus Group criteria. Clinical, demographic, and serological data, as well as malignancy incidence and survival outcomes, were prospectively collected over a median follow-up of 9.5 years [IQR 9.2–9.9]. SIRs were calculated using data from the GLOBOCAN project. Independent predictors of lymphoma and other malignancies were identified through multivariate Cox regression analysis. Cancer-related mortality and its impact on overall survival were assessed using relative risk (RR) estimates.
Results: Among the 314 patients, 22 incident malignancies (7.01%) were identified: 11 hematologic (all NHL) and 11 solid tumors. The overall cancer risk was elevated (SIR: 1.68; 95% CI: 1.68–1.69). A markedly increased risk was observed for NHL (SIR: 15.36; 95% CI: 15.32–15.40) and hematologic malignancies overall (SIR: 3.55; 95% CI: 3.54–3.56), while a modest increase was seen for solid tumors (SIR: 1.54; 95% CI: 1.53–1.55). Multivariate analysis identified older age (HR: 1.06; 95% CI: 1.01–1.11), smoking (HR: 3.56; 95% CI: 1.24–10.24), lymphadenopathy (HR: 3.34; 95% CI: 1.33–8.37), splenomegaly (HR: 14.04; 95% CI: 1.36–144.51), and cryoglobulinemia (HR: 9.12; 95% CI: 1.93–43.07) as independent predictors of malignancy. Cryoglobulinemia emerged as the strongest predictor of lymphoma (HR: 11.07; 95% CI: 1.18–103.75). A prior history of cancer significantly differentiated hematologic malignancies from solid tumors (HR: 26.97; 95% CI: 1.26–418.46). Malignancies accounted for 23.8% of all deaths in the cohort (RR: 2.21; 95% CI: 1.18–4.12).
Conclusion: Patients with Sjögren’s disease are at increased risk of developing hematologic malignancies—particularly non-Hodgkin lymphoma—and, to a lesser extent, solid tumors. Cryoglobulinemia emerged as the strongest independent predictor of lymphoma. Malignancies significantly contribute to mortality, highlighting the need for targeted surveillance and timely intervention in high-risk patients. Further research is needed to validate findings and guide personalized approaches to improve outcomes.
