Abstract: Methods of identifying a subject having an increased risk of developing anthracycline-related cardiotoxicity are provided. Such methods may include isolating a DNA sample from a biological specimen from the subject; genotyping the DNA sample to determine a copy number of a variant allele that increases the risk of developing chemotherapy-induced cardiotoxicity; and identifying the subject as having an increased risk of developing anthracycline-related cardiotoxicity when the copy number is at least one. In some embodiments, the methods may include optimally administering a therapeutically effective dose of a chemotherapy agent or an alternative non-cardiotoxic chemotherapeutic agent to the subject.

Abstract: In one embodiment, a gene expression signature for predicting risk of developing therapy-related myelodysplasia or acute myeloid leukemia (t-MDS/AML) after autologous hematopoietic cell transplantation (aHCT) is provided. In another embodiment, a method for predicting a risk for development of t-MDS/AML after aHCT is provided. Such a method may include providing a biological sample that contains CD34 cells from a subject; detecting a test expression level of a set of two or more genes of a gene expression signature; comparing the test expression level of a set of corresponding training expression levels that include a training case expression level and a training control expression level; and predicting a high risk of developing t-MDS/AML when the test expression level is at or about the training case expression level or predicting a low risk of developing t-MDS/AML when the test expression level is at or about the training control expression level.
