Tantalizing connections between autoimmune rheumatic diseases and cancer have become increasingly evident over the past several decades. These connections are complex, with different relationships in frequency, timing, and types of cancers observed in different diseases or disease subgroups. Several recent advances from disparate fields have begun to illuminate the dynamic and bidirectional interactions occurring at the cancer–immune system interface which may be relevant to understanding the origins of autoimmunity ([1]). These interactions include the existence of potent anticancer immune responses that limit tumor growth, as well as multiple immune and inflammatory pathways that can contribute to tumor growth and robustness. The striking ability of immune checkpoint inhibitors to reveal powerful anticancer immune responses in patients with cancer highlights the fact that natural immune responses to cancers occur, and may regulate the emergence of cancer ([2]).
