Objective. To examine mortality rates in the largest systemic lupus erythematosus (SLE) cohort ever assembled.Methods. Our sample was a multisite international SLE cohort (23 centers, 9,547 patients). Deaths were ascertained by vital statistics registry linkage. Standardized mortality ratio (SMR; ratio of deaths observed to deaths expected) estimates were calculated for all deaths and by cause. The effects of sex, age, SLE duration, race, and calendar-year periods were determined.Results. The overall SMR was 2.4 (95% confidence interval 2.3-2.5). Particularly high mortality was seen for circulatory disease, infections, renal disease, non-Hodgkin's lymphoma, and lung cancer. The highest SMR estimates were seen in patient groups character-

OBJECTIVE To update estimates of cancer risk in SLE relative to the general population. METHODS A multisite international SLE cohort was linked with regional tumor registries. Standardized incidence ratios (SIRs) were calculated as the ratio of observed to expected cancers. RESULTS Across 30 centres, 16,409 patients were observed for 121,283 (average 7.4) person-years. In total, 644 cancers occurred. Some cancers, notably hematologic malignancies, were substantially increased (SIR 3.02, 95% confidence interval, CI, 2.48, 3.63), particularly non-Hodgkin’s lymphoma, NHL (SIR 4.39, 95% CI 3.46, 5.49) and leukemia. In addition, increased risks of cancer of the vulva (SIR 3.78, 95% CI 1.52, 7.78), lung (SIR 1.30, 95% CI 1.04, 1.60), thyroid (SIR 1.76, 95% CI 1.13, 2.61) and possibly liver (SIR 1.87, 95% CI 0.97, 3.27) were suggested. However, a decreased risk was estimated for breast (SIR 0.73, 95% CI 0.61–0.88), endometrial (SIR 0.44, 95% CI 0.23–0.77), and possibly ovarian cancers (0.64, 95% CI 0.34–1.10). The variability of comparative rates across different cancers meant that only a small increased risk was estimated across all cancers (SIR 1.14, 95% CI 1.05, 1.23). CONCLUSION These data estimate only a small increased risk in SLE (versus the general population) for cancer over-all. However, there is clearly an increased risk of NHL, and cancers of the vulva, lung, thyroid, and possibly liver. It remains unclear to what extent the association with NHL is mediated by innate versus exogenous factors. Similarly, the etiology of the decreased breast, endometrial, and possibly ovarian cancer risk is uncertain, though investigations are ongoing.

These recommendations were developed based on a synthesis of international guidelines, supporting evidence, and expert consensus considering the Canadian healthcare context with the intention of promoting best practices and improving healthcare delivery for persons with RA.

Objective. There is increasing evidence in support of an association between systemic lupus erythematosus (SLE) and malignancy, but in earlier studies the association could not be quantified precisely. The present study was undertaken to ascertain the incidence of cancer in SLE patients, compared with that in the general population.Methods. We assembled a multisite (23 centers) international cohort of patients diagnosed as having SLE. Patients at each center were linked to regional tumor registries to determine cancer occurrence. Standardized incidence ratios (SIRs) were calculated as the ratio of observed to expected cancers. Cancers expected were determined by multiplying person-years in the cohort by the geographically matched age, sex, and calendar year-specific cancer rates, and summing over all person-years.Results. The 9,547 patients from 23 centers were observed for a total of 76,948 patient-years, with an average followup of 8 years. Within the observation interval, 431 cancers occurred. The data confirmed an Dr.

ABSTRACT. Objective. The Canadian Rheumatology Association (CRA) has developed recommendations for the pharmacological management of rheumatoid arthritis (RA) with traditional and biologic disease-modifying antirheumatic drugs (DMARD) in 2 parts. Part II, focusing on specific safety aspects of treatment with traditional and biologic DMARD in patients with RA, is reported here. Methods. Key questions were identified a priori based on results of a national needs-assessment survey. A systematic review of all clinical practice guidelines and consensus statements regarding treatment with traditional and biologic DMARD in patients with RA published between January 2000 and June 2010 was performed in Medline, Embase, and CINAHL databases, and was supplemented with a "grey literature" search including relevant public health guidelines. Systematic reviews of postmarketing surveillance and RA registry studies were performed to update included guideline literature reviews as appropriate. Guideline quality was independently assessed by 2 reviewers. Guideline characteristics, recommendations, and supporting evidence from observational studies and randomized trials were synthesized into evidence tables. The working group voted on recommendations using a modified Delphi technique.Results. Thirteen recommendations addressing perioperative care, screening for latent tuberculosis infection prior to the initiation of biologic DMARD, optimal vaccination practices, and treatment of RA patients with active or a history of malignancy were developed for rheumatologists, other primary prescribers of RA drug therapies, and RA patients. Conclusion. These recommendations were developed based on a synthesis of international RA and public health guidelines, supporting evidence, and expert consensus in the context of the Canadian health system. They are intended to help promote best practices and improve healthcare delivery for persons with RA. (First Release June 15 2012; J Rheumatol 2012;39:1583-602; doi:10.3899 Recommendations provided here are intended to be read in conjunction with the Canadian Rheumatology Association Recommendations for the Pharmacological Management of Rheumatoid Arthritis. These recommendations address specific safety questions that were identified a priori and are not intended to cover all safety aspects concerning treatment with traditional and biologic disease modifying antirheumatic drugs (DMARD).Traditional and biologic DMARD have greatly enhanced the care of persons with rheumatoid arthritis (RA); however, potential risks associated with their use need be considered. The Canadian Rheumatology Association (CRA) has developed recommendations for the pharmacological management of RA with traditional and biologic DMARD in 2 parts. Part I described the development process of CRA recommendations in detail and included 5 overarching RA care principles along with 26 treatment recommendations 1 . Part II, reported here, focuses on specific safety aspects of treatment with traditional and biologic DMARD in patients with ...
