About 1 in 715 young adults is a survivor of childhood malignancy, but these individuals are at increased risk of considerable treatment-related morbidity or even mortality. A recent study suggests that at least 60% have one or more chronic health problems, whilst about 20% have three or more. The principle goal of long-term follow-up (LTFU) of survivors is to decrease the severity of late treatment complications by performing appropriate surveillance to detect incipient toxicity, and by facilitating timely diagnosis and management of emerging or established late adverse effects. The content of LTFU is dictated by the type and amount of treatment for the malignancy, and has been defined in recent clinical guidelines. Moreover, LTFU allows provision of survivor education, psychosocial support and health promotion advice. However, considerable variation exists in how LTFU is performed, with several alternative models involving a range of professionals in a variety of locations, depending on numerous clinical and organisational factors. There is increasing utilisation of multidisciplinary teams, and recognition of the importance of effective transition strategies whereby care is transferred to more age-appropriate providers, usually after a period of joint care in adolescence. It is of paramount importance to ascertain and meet the needs of survivors themselves.

Background Anthracycline cardiomyopathy is of concern in children treated for acute myeloid leukaemia (AML), but there are few data on the incidence and natural history of cardiotoxicity after AML treatment in the United Kingdom, where regimens have included high anthracycline exposure. Procedure Prevalence and predictors of cardiotoxicity were retrospectively reviewed in 124 children treated on the MRC AML 10 and AML 12 trials in a single, large centre from November 1987 to September 2004. Subclinical cardiotoxicity was defined as a shortening fraction of less than 28% and clinical cardiomyopathy as evidence of heart failure, and both were classified as late cardiotoxicity 1 year after completing first line therapy. Results Cumulative survival was 61% at 10 years. The prevalence of early and late cardiotoxicity was 13.7% (95%‐CI: 8.2–22.0%) and 17.4% (95%‐CI: 10.9–26.8%), respectively. Early cardiotoxicity was a strong predictor (OR = 9.18; 95%‐CI: 2.10–40.11; P < 0.005) and children who received salvage therapy following relapse showed a trend towards increased late cardiotoxicity (OR = 3.53; 95%‐CI: 0.86–14.48; P < 0.08). Subclinical cardiotoxicity resolved spontaneously in all but one case, but clinical cardiomyopathy always required continuing therapy. Two children died of cardiomyopathy and six remained on medical therapy. Conclusions Anthracycline cardiotoxicity remains a major concern for survivors of childhood AML and correlates with early cardiotoxicity and treatment intensity. Long‐term follow‐up is required to fully determine the outcome for children with subclinical cardiotoxicity. Pediatr Blood Cancer 2011;56:625–630. © 2011 Wiley‐Liss, Inc.

It is difficult to draw conclusions about the effectiveness of technologies for reducing or preventing cardiotoxicity and about the use of cardiac markers in children as the evidence is limited in quantity and quality. The lack of standardisation for monitoring and reporting cardiac performance is problematic. Not all studies report effectiveness in terms of cardiac outcomes and event-free survival with supporting statistical analyses. Studies are mostly small and of short duration, making generalisation difficult. Increasing numbers of survivors of childhood cancer treated with anthracyclines will experience cardiac damage and require long-term surveillance and management. This will have an impact on cardiac services and costs. Diverse medical problems and other late sequelae that affect cardiac outcome will have an impact on other specialist services. Mechanisms to reduce or prevent cardiotoxicity from anthracycline therapy and cardiac markers to improve monitoring could alter the extent of this impact on service provision. RCTs of the different methods for reducing or preventing cardiotoxicity in children treated with anthracyclines for cancer with long-term follow-up are needed to determine whether the technologies influence the development of cardiac damage. Cost-effectiveness research is also required.

Background Evidence‐based guidelines are needed to guide effective long‐term follow‐up (LTFU) of childhood cancer survivors (CCS) at risk of late adverse effects (LAEs). We aimed to ascertain the use of LTFU guidelines throughout Europe, and seek views on the need for pan‐European LTFU guidelines. Procedures One expert clinician from each of 44 European countries was invited to participate in an online survey. Information was sought regarding the use and content of LTFU guidelines in the respondent's centre and country, and their views about developing pan‐European LTFU guidelines. Results Thirty‐one countries (70%) responded, including 24 of 26 full EU countries (92%). LTFU guidelines were implemented nationally in 17 countries (55%). All guidelines included recommendations about physical LAEs, specific risk groups and frequency of surveillance, and the majority about psychosocial LAEs (70%), and healthy lifestyle promotion (65%). A minority of guidelines described recommendations about transition to age‐appropriate LTFU services (22%), where LTFU should be performed (22%) and by whom (30%). Most respondents (94%) agreed on the need for pan‐European LTFU guidelines, specifically including recommendations about surveillance for specific physical LAEs (97%), action to be taken if a specific LAE is detected (90%), minimum requirements for LTFU (93%), transition and health promotion (both 87%). Conclusions Guidelines are not universally used throughout Europe. However, there is strong support for developing pan‐European LTFU guidelines for CCS. PanCareSurFup (http://www.pancare.eu) will collaborate with partners to develop such guidelines, including recommendations for hitherto relatively neglected topics, such as minimum LTFU requirements, transition and health promotion.
