Show moreThe aim of our study was to assess the cumulative incidence and severity ('burden') of late effects in a single-centre cohort of childhood haematopoietic stem cell transplantation (HSCT) survivors, at least 2 years after transplantation. The presence and severity of late effects in each survivor was documented according to the Common Terminology Criteria for Adverse Events (version 3.0). The burden of late effects was graded from mild to disabling/life-threatening. Risk factors for a high burden of late effects were assessed by univariate and multivariate logistic regression analyses. Among 162 survivors of HSCT seen in our late effects outpatient clinic, cumulative incidence of late effects was 93.2% after a median follow-up time of 7.2 years (range 2.0-21.0 years) after HSCT. The burden of late effects was mild, moderate, severe and disabling in 28, 41, 24 and 1% of survivors respectively. Risk factors for a severe or disabling burden of late effects were older age at HSCT (P for trend <0.001) and a conditioning regimen including irradiation OR 2.2, 95% CI 1.1-4.7, P = 0.03). In conclusion, a high burden of late effects is found in childhood HSCT survivors after a median follow-up of only 7 years.
