The cohort was followed up for cancer by linkage to the Danish Cancer Registry. Based on the age, sex, and calendar specific cancer rates of the general population of Denmark, standardised incidence ratios (SIRs) were calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The patients with CLE or SLE were followed for 40.724 person-years, each group\u2019s average duration of follow-up being 6.9 and 8.1\u2009years. The SIR for overall cancer (except non-melanoma skin cancer (NMSC)) was increased in patients with CLE 1.35 (95%CI 1.15 to 1.58) and patients with SLE 1.45 (95%CI 1.30 to 1.62). Both groups had high risks of hematological \u2013 including a 3\u20134-fold increased risk of non-Hodgkin lymphoma \u2013, pancreatic, and lung cancers. Several cancers associated with oncogenic viruses as liver and tongue\/mouth\/pharynx were increased in the SLE group, while the risk of ovarian cancer was increased 2\u20134-fold only in the CLE group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The overall risk of cancer was significantly increased in both patients with CLE and SLE.
