Rheumatologic manifestations of malignancy

Area of Science:

• Rheumatology
• Oncology
• Internal Medicine

Background:

• The association between rheumatic syndromes and malignancy is a recognized clinical challenge.
• Several rheumatic conditions are increasingly linked to an elevated risk of developing cancer.
• Understanding these associations is vital for timely diagnosis and management.

Purpose of the Study:

• To review the spectrum of rheumatic syndromes associated with malignancy.
• To emphasize the importance of malignancy screening in specific rheumatic patient groups.
• To discuss the clinical implications of these associations for patient care.

Main Methods:

• Literature review of studies examining the relationship between rheumatic diseases and cancer.
• Analysis of reported cases and epidemiological data.
• Synthesis of findings on specific rheumatic conditions and their associated malignancies.

Main Results:

• Malignancy is prevalent in patients with unclassified rheumatic syndromes.
• Associated arthropathies include knee effusions, sacroiliitis, and adult-onset Still's disease.
• Strong associations exist between dermatomyositis (with or without myositis) and cancer, mixed cryoglobulinemia and hepatitis C virus/hepatocellular carcinoma/non-Hodgkin's lymphoma, and other rheumatic features with malignancy.

Conclusions:

• Screening for malignancy is essential in patients presenting with specific rheumatic syndromes, particularly dermatomyositis.
• Early detection of cancer in rheumatic patients can significantly impact prognosis.
• Further research is warranted to elucidate the underlying mechanisms of these associations.
