Prognosis of ETMR remains dismal despite multimodal therapy. LIN28A immunostaining and 19q13.42 amplification should be systematically done to secure the diagnosis. Complete surgical resection, radiotherapy, and high-dose chemotherapy are associated with better outcome.
SummaryCataract was prospectively assessed by serial slip lamp tests in 271 patients included in the Leuc emie Enfants Adolescents (LEA) programme, the French cohort of childhood leukaemia survivors. All had received haematopoietic stem cell transplantation (HSCT) after total body irradiation (TBI, n = 201) or busulfan-based (n = 70) myeloablative conditioning regimen. TBI was fractionated in all but six patients. The mean duration of followup from HSCT was 10Á3 years. Cataract was observed in 113/271 patients (41Á7%); 9/113 (8Á1%) needed surgery. Cumulative incidence after TBI increased over time from 30% at 5 years to 70Á8% and 78% at 15 and 20 years, respectively, without any plateau thereafter. The 15-year cumulative incidence was 12Á5% in the Busulfan group. A higher cumulative steroid dose appeared to be a cofactor of TBI for cataract risk, in both univariate and multivariate Cox analysis. In the multivariate analysis, cataract had an impact in two quality of life domains: 'the role limitation due to physical problems' and 'the role limitation due to emotional problems'. These data suggest that with increasing follow-up, nearly all patients who receive TBI, even when fractionated, will suffer from cataract that can impact on their quality of life and that high cumulative steroid dose is a cofactor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
