Haematological Malignancies in Systemic Sclerosis Patients: Case Reports and Review of the World Literature

Background. The association of systemic sclerosis (SSc) and haematological cancers was reported in a large number of case reports and cohort studies, describing SSc patients with highly heterogeneous clinical pictures. Objective. We reviewed the literature to better describe SSc patients with haematological malignancies. Methods. SSc cases complicated by haematological malignancies described in the world literature were collected; other 2 cases referred to our centre were reported. Results. One hundred-thirty SSc subjects were collected from 1954 up to date. The mean age of patients at cancer diagnosis was 56.1 ± 16.7 years; 72% of patients were females. In 60% of cases, the diagnosis of haematological malignancy was described within 5 years of SSc diagnosis. In 7.8% of cases, coexistence of Sjögren's syndrome or other autoimmune disorders was cited. Sixty-six cases with lymphoma (in the majority of cases B-cell neoplasms), 28 with leukaemia (chronic lymphocytic form in 9), 14 with multiple myeloma plus one solitary IgM plasmocytoma, and 16 with myeloproliferative disorders were found. No specific SSc subsets seem to be related to haematological malignancies. Conclusions. We remarked the importance of clinical work-up in SSc, in order to early diagnose and treat eventual occult haematological malignancies, especially during the first years of the disease.

Paraneoplastic systemic sclerosis: About 3 cases and review of literature

OBJECTIVE

Association between cancer and systemic sclerosis (SSc) has been described. However, paraneoplastic SSc is not well known. The aim of this article is to describe cases of paraneoplastic systemic sclerosis and to compare them to other cases of the literature, to find characteristics that can make suspect a paraneoplastic mechanism when SSc is diagnosed.

METHODS

We retrospectively analyzed patients, in our department who, over the last 15 years, presented with Raynaud's phenomenon with a diagnosis of SSc (including cancer during the period of SSc). Treatment of cancer had to be concomitted with an improvement of sclerosis and/or negativation of antinuclear antibodies. Review analysis of other cases was made with Pubmed.

RESULTS

Three patients responded to the criteria. Two of them had an ovarian cancer with peritoneal carcinomatosis and a concomitted SSc. One had a colon cancer with an ovarian metastasis diagnosed 1 year before SSc. None of them had anti-ENA antibody. One had a normal capillaroscopy. After treatment of cancer, all of them had an improvement of sclerosis and a negativation of antinuclear antibodies.

CONCLUSION

We believe that physicians should be aware of paraneoplastic SSc when presentation of SSc is atypical: no anti-ENA (anti-SCl70 or anti-centromere) or normal capillaroscopy, in particular gynecologic cancer in women.

Systemic Sclerosis and Malignancy: A Review of Current Data

Systemic sclerosis (SSc) is associated with increased risk of malignancy. The organ systems most commonly affected are the lungs, the breasts and the hematological system. Risk factors predisposing a SSc patient for development of malignancy are not well defined, and the pathogenic basis of the association is yet to be explained. The incidence of malignancies in SSc patients is variable from one report to another, but most importantly, questions regarding the role of immunosuppressive therapies and the effect of autoantibodies have weak or sometimes contradictory answers in most of the currently available literature and physicians have no available guidelines to screen their SSc patients for malignancies. The lack of a concretely defined high-risk profile and the absence of malignancy screening guidelines tailored for SSc patients raise the importance of the need for more studies on the association of SSc and cancer and should incite rheumatology colleges to develop specific recommendations for the clinician to follow while approaching patients with SSc.
