Background: The Late Effects of Childhood Cancer task force of the Dutch Childhood Oncology Group (DCOG LATER) developed a guideline for follow-up of asymptomatic cardiac dysfunction in childhood cancer survivors (CCS). In this paper, we present the methods, available evidence and final recommendations of our guideline. Materials and methods: A multidisciplinary working group specified clinical questions that should be answered to get to recommendations for the guideline. We carried out short or extensive evidence summaries and determined methodological quality of studies and levels of evidence in order to answer all clinical questions. When evidence was lacking for CCS, we carefully extrapolated evidence from other populations. Final recommendations were based on evidence and consensus. Results: There was high-level evidence for the increased risk of cardiac dysfunction in CCS and its main risk factors. Evidence was lacking regarding the prognosis, diagnosis and treatment of cardiac dysfunction in CCS. We recommended echocardiographic screening for asymptomatic cardiac dysfunction in CCS treated with cardiotoxic treatments and counseling about potential advantages and disadvantages of our screening recommendations. Conclusion: The DCOG LATER guideline recommends risk-based screening for asymptomatic cardiac dysfunction in CCS, but it should be noted that recommendations are not completely supported by evidence in CCS.
