The widespread and non-pathogenic Torque Teno virus (TTV) has emerged as a surrogate of the immune status of its host, with prior studies linking TTV load to insufficient and excessive immunosuppression and thus indirectly to graft rejection and infection. Its relationship to malignancy in kidney transplant recipients is unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective observational single center study evaluated 428 patients who underwent kidney transplantation between 2016 and 2019 at the General Hospital of Vienna, Austria. TTV was measured by quantitative polymerase chain reaction in plasma and the primary outcome was the incidence of the first malignancy during years 2\u20135 post-transplant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 53 patients developed malignancy (53% cutaneous keratinocyte cancer). The mean log10 TTV load during months 4 to 12 post-transplant (logTTVm4\u201312) was associated with increased malignancy risk with a hazard ratio (HR) of 1.25 [95% confidence interval (CI) 1.02\u20131.54] in unadjusted analysis and 1.20 (95% CI 0.97\u20131.48) after adjustment for age, sex, smoking, and body mass index. In a subgroup, the result remained consistent after additional adjustment for tacrolimus and mycophenolate exposure (HR 1.31, 95% CI 1.03\u20131.67). Patients with logTTVm4\u201312 &amp;gt;8, a cut-off we previously proposed to indicate infection risk, had an HR of 2.10 (95% CI 1.22\u20133.60).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that a high TTV load\u2014indicating a state of intense immunosuppression\u2014predicts malignancy after kidney transplantation.
