Both cancer and autoimmune diseases have been associated with numerous factors that may independently lead to the development of either disease. When these factors overlap the difficulty in assessing association is compounded. The numerous factors that are thought to cause systemic lupus erythematosus (SLE), which leads to the development of cancer, makes the study of an association between the 2 diseases challenging. The purpose of this study was to examine whether the risk of cancer development increased in SLE patients compared to the risk in non-SLE patients. Researchers have not shown consistent relationships of cancer development in patients with SLE; however, consideration of the various factors that contribute to the diseases is necessary to measure an association between the 2 diseases. This study used the Clinical Practice Research database (CPRD), a large, population-based database to test the relationship between SLE and cancer. A matched retrospective cohort study among SLE (n=3025) and non-SLE (n=180555) patients was conducted using the propensity score methodology to help balance the differences between the comparison groups. The propensity score methodology created a similar distribution of observed baseline covariates between the 2 groups. With adjustment for age, the predictor variable of SLE indicates that a patient with SLE is still 2.7 times more likely to develop cancer than is a non-SLE patient. The study outcomes could promote positive social change by reinforcing current recommendations for cancer screenings in persons with SLE, which could enhance the ability to detect cancer early enough to decrease mortality because of cancer in persons with SLE.
