Hepatic injury after treatment for childhood cancer: A report from the St. Jude Lifetime Cohort study.

Abstract

10567 Background: We assessed hepatic injury (HI) in a large cohort of childhood cancer survivors (CCS). Methods: We measured aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in 2751 SJLIFE CCS ( > 10 years (yrs) post-diagnosis, age ≥18 yrs), and graded using the Common Terminology Criteria for Adverse Events (CTCAE) v 4.03. Multivariable log binomial regression was used to estimate associations between demographic and clinical factors and grades 1–4 ALT and AST. Variables with a p < 0.1 were examined in multivariable models. Results: 1339 (48.7%) CCS were female. 2271 (82.6%) were non-Hispanic white (NHW). Median age at diagnosis - 7.4 yrs, median age at evaluation - 31.4 yrs, and median time from diagnosis to evaluation - 23.2 yrs. 177 (6.4%) had grades 1-4 AST (grade 1 = 164, grade 2 = 9, grade 3 = 4), and 421 (15.3%) had grades 1-4 ALT (grade 1 = 394, grade 2 = 18, grade 3 = 8). The multivariable results are shown in the table below. Conclusions: Male gender, obesity, hepatitis C virus infection, and treatment with busulfan are risk factors for increased AST and ALT. V10 is an additional risk factor for increased ALT. These results may guide future treatment designs and lifestyle interventions. [Table: see text]
