Sjögren Syndrome and Cancer

Area of Science:

• Rheumatology
• Oncology
• Immunology

Background:

• Established association between rheumatic diseases and malignancy.
• Limited understanding of the pathogenesis linking rheumatic diseases and cancer.
• Strong evidence connects Sjögren syndrome with lymphoma, including risk factors.

Purpose of the Study:

• To review and synthesize current data on malignancies associated with primary Sjögren syndrome.
• To highlight specific cancers, including non-Hodgkin lymphoma, thyroid cancer, multiple myeloma, and skin cancers.
• To discuss the clinical implications of these associations for patient care and research.

Main Methods:

• Literature review of studies investigating malignancy in primary Sjögren syndrome.
• Analysis of epidemiological data and case reports.
• Synthesis of findings on specific cancer types and risk factors.

Main Results:

• Primary Sjögren syndrome is associated with an increased risk of several malignancies.
• Non-Hodgkin lymphoma is a significant concern, with identified risk factors.
• Associations with thyroid cancer, multiple myeloma, and skin cancers are also discussed.

Conclusions:

• The link between Sjögren syndrome and malignancy has significant clinical implications.
• Understanding these associations enhances knowledge of both autoimmunity and cancer development.
• Further research is warranted to elucidate the underlying pathogenetic mechanisms.
