Cardiac transplantation in childhood cancer survivors in Great Britain.
The aim of this study was to identify patients treated in Great Britain for childhood cancer and subsequently referred for cardiopulmonary transplantation in order to assess diagnosis, cancer treatment, management and outcome. Computerised record linkage between the National Registry of Childhood Tumours and the national transplant database held and maintained by the United Kingdom Transplant Support Service Authority (UKTSSA) was used to identify patients. Verification and clinical details were then obtained from the oncology and transplant centres. 16 patients were identified from the 31992 cases of childhood malignancy diagnosed in Britain since 1970. These comprised 13 heart transplants, 2 heart/lung transplants and 1 patient who died while on the heart transplantation waiting list. All 14 potential heart transplant patients had cardiomyopathy presumed secondary to anthracycline therapy. The original diagnoses were acute myeloblastic leukaemia (3), Wilms' tumour (4), rhabdomyosarcoma (2) and one each of five different solid tumours. Median age at diagnosis was 44 months (range 4-165 months). Median anthracycline dose was 413 mg/m2 (range 240-680 mg/m2). 13 of the 14 potential cardiac transplantation patients were more than 2 years from end of their cancer treatment before requiring transplantation and the transplantation was performed 2-126 months after onset of cardiac failure at a median age of 163 months. Five year actuarial survival from transplantation was 74%. There was no recurrence of the original malignancy in any of these patients. Both heart/lung patients died, 3 and 11 months after the transplant. These heart transplantation data suggest that, in Britain, survival compares favourably with that of patients whose heart transplant was required for other causes of cardiomyopathy. This indicates that patients successfully treated for childhood cancer should not be excluded from transplant programmes.
