Managing cancer risk in patients with systemic lupus erythematous

Expert Rev Clin Immunol. 2018 Oct;14(10):793-802. doi: 10.1080/1744666X.2018.1519394. Epub 2018 Sep 14.


Introduction: Numerous studies have clearly demonstrated that there is an altered cancer risk profile in patients with systemic lupus erythematous (SLE) versus the general population. This includes a higher risk of certain cancers (e.g. hematologic, lung) and a decreased risk of others (e.g. breast cancer). Several determinants could be behind this altered risk; these include immunosuppressant drugs, viral exposures, genetic factors, and other variables. Area covered: We review what is known regarding specific risk profiles and risk factors for some key cancers in SLE, including hematologic malignancies and lung cancers. In light of this, we examine current guidelines and practices regarding cancer screening, and propose ways that patients and physicians might help manage cancer risk in SLE. Expert commentary: Despite significant progress over the past decade, not many risk factors have been precisely identified. A better understanding of the elements that drive malignancy risk in systemic autoimmune rheumatic diseases may permit the further development of guidelines (regarding. cancer screening) for SLE patients.
