Abstract: PURPOSE OF REVIEW: To examine recent data about the association between rheumatic disorders and cancer. This article focuses on paraneoplastic rheumatic disorders, which usually precede by a short period of time the diagnosis of malignancy, and on malignant transformation, which occurs late in the course of rheumatic disorders. Evidence of causality between malignancies and rheumatic disorders was reviewed based on statistical indicators (standardized incidence ratios and odds ratios) and by applying Bradford Hill's criteria of causality. RECENT FINDINGS: Firm epidemiological evidence was found attesting that dermatomyositis and polymyostis may present as paraneoplastic syndromes. Several other musculoskeletal disorders may be present akin to paraneoplastic syndrome, based on clinicians' impressions, but with scarce epidemiological evidence supporting a causal determinism. In contrast, robust evidence has accumulated on the role of longstanding rheumatoid arthritis, Sjögren's syndrome and systemic sclerosis as premalignant conditions. Evidence that systemic lupus erythematosus may evolve into lymphoma is equivocal. SUMMARY: The link between malignancies and rheumatic disorders may impact on clinical practice. First, paraneoplastic rheumatic syndromes can provide the clinician with hints for earlier diagnosis of occult cancer. Second, the risk of malignant transformation during the course of rheumatic disorders may motivate the search for strategies aimed at prevention.

Abstract: OBJECTIVE: To present the data available supporting the existence of an arthropathy associated with hepatitis C infection. METHODS: The MEDLINE database was searched for "arthritis" intersecting with "hepatitis C" in addition to the authors' investigations and experience on this subject. RESULTS: Arthritis, not otherwise explained, has been noted in 2% to 20% of hepatitis C virus (HCV) patients. This arthritis is rheumatoid-like in two thirds of the cases and a waxing/waning oligoarthritis in the rest. Cryoglobulinemia alone does not explain the arthritis, and there is difficulty in differentiating it from rheumatoid arthritis. The arthropathy is nonerosive/nondeforming. Whereas nonsteroidal anti-inflammatory drugs, low-dose corticosteroids, and hydroxychloroquine may be helpful, conventional treatment of arthritis may be problematic in the context of viral hepatitic arthropathy. Antiviral therapy is most effective, even without viral clearance, but rheumatic complications may ensue. CONCLUSIONS: HCV arthropathy should be considered in the differential diagnosis of new-onset arthritis.

Abstract: OBJECTIVES: Rheumatic disorders associated with cancer include a variety of conditions, most of which have no features distinguishing them from idiopathic rheumatic disorders. It is generally held that an extensive search for occult malignancy in most rheumatic syndromes is not recommended unless accompanied by specific findings suggestive of malignancy. The objective of this review are to identify rheumatic syndromes associated with cancer, to call attention to features that may suggest the presence of a hidden cancer, and to examine the role to additional clinical and laboratory data as clues to the possible neoplastic cause of those syndromes. METHODS: A MEDLINE search of the literature dealing with cancer-associated rheumatic syndromes was conducted. RESULTS: Review of the literature identified significant progress in this area. First, the association of malignancy with certain rheumatic syndromes was convincingly established, such as asymmetric polyarthritis presenting in the elderly with an explosive onset, rheumatoid arthritis with monoclonal gammopathy, Sjögren's syndrome with monoclonality, hypertrophic osteoarthropathy, dermatomyositis, polymyalgia rheumatica with atypical features, Lambert-Eaton myasthenic syndrome, palmar fasciitis and arthritis, eosinophilic fasciitis poorly responsive to corticosteroid therapy, erythema nodosum lasting more than 6 months, and onset of Raynaud's phenomenon or cutaneous leukocytoclastic vasculitis after age 50 years. Second, the list of cancer-associated rheumatic syndromes was extended by including additional entities such as benign edematous polysynovitis, sacroiliitis, adult-onset Still's disease, dermatomyositis sine myositis, systemic sclerosis, Sweet's syndrome, osteomalacia, skeletal hyperostosis, antiphospholipid syndrome, and essential mixed cryoglobulinemia. Third, evidence was provided substantiating that certain long-standing rheumatic syndromes, in particular rheumatoid arthritis, Felty's syndrome, Sjögren's syndrome, dermatomyositis, systemic sclerosis, systemic lupus erythematosus, and temporal arteritis behave like "premalignant conditions." Fourth, it was shown that the recognized tumor markers alpha-fetoprotein, prostate-specific antigen, CA-125, CA 19-9, and CA-3 have low sensitivity and specificity in screening for occult cancer in a population of rheumatic patients, whereas the presence of a monoclonal gammopathy in rheumatoid arthritis and the monoclonal antibody 17-109 in Sjögren's syndrome are reliable signs of malignant transformation. CONCLUSIONS: The presence of specific rheumatic syndromes and certain clinical and laboratory findings may justify a workup for hidden cancer. Studies of the epidemiology of the cancer-associated rheumatic syndromes and evaluation of the validity of aforementioned clues in prospective studies are goals for future investigations.

Abstract: OBJECTIVE: To characterize hepatitis C virus (HCV)-related arthropathy and to evaluate the response to treatment with interferon-alpha (INF-alpha). METHODS: We studied 28 HCV-infected patients with arthritis. All patients underwent complete clinical, laboratory and radiological evaluation, including assessment and follow-up by a rheumatologist. Twenty-five patients were treated with INF-alpha for a median period of 12 months. RESULTS: All patients were HCV-RNA positive (genotype 1b in 65%). The mean duration of arthropathy-related symptoms prior to the diagnosis of HCV infection was 12 months. 19 patients (68%) had symmetric polyarthritis and 19 (68%) had morning stiffness > or = 60 min. None of the patients had erosive disease or subcutaneous nodules. 12 (43%) had detectable cryoglobulin (mean cryocrit: 3.6 +/- 3.5%), 17 (61%) had rheumatoid factor (RF) (median titer: 1:80), and only 15 (54%) had elevated ESR. 14 patients (50%) had > or = 4 ACR (American College of Rheumatology) criteria for the diagnosis of rheumatoid arthritis (RA), 9 of whom were mistakenly diagnosed and previously treated as RA patients. Only 3 patients had a satisfactory response to previous treatment with anti-inflammatory or disease modifying drugs. Complete or partial response of arthritis-related symptoms in INF-alpha treated patients was observed in 44% and 32%, respectively. Cryoglobulin became undetectable in 9 of 12 patients. However, a complete biochemical and virological end-of-treatment response was achieved in only 8 (36%) and 5 patients (20%), respectively. CONCLUSION: HCV arthropathy should be considered in the differential diagnosis of any patient with arthritis, even in the absence of liver disease. Treatment with interferon-alpha may lead to substantial clinical improvement of HCV-related arthritis even without a complete biochemical or virological response.
