Late Effects of Treatment for Childhood Cancer (PDQ®): Treatment - Health Professional Information [NCI] - Subsequent Neoplasms

continued...

Subsequent Neoplasms and Genetic Susceptibility

Literature clearly supports the role of chemotherapy and radiation in the development of SNs. However, interindividual variability exists, suggesting that genetic variation has a role in susceptibility to genotoxic exposures, or that genetic susceptibility syndrome confers an increased risk of cancer, such as Li-Fraumeni syndrome. Previous studies have demonstrated that childhood cancer survivors with either a family history of cancer, but more so, presence of Li-Fraumeni syndrome, carry an increased risk of developing an SN.[58,59]

The risk of SNs could potentially be modified by mutations in high-penetrance genes that lead to these serious genetic diseases (e.g., Li-Fraumeni syndrome).[59] However, the attributable risk is expected to be very small because of the extremely low prevalence of mutations in high-penetrance genes.

Table 1 below summarizes the spectrum of neoplasms, affected genes, and Mendelian mode of inheritance of selected syndromes of inherited cancer predisposition.

Syndrome Major Tumor Types Affected Gene Mode of Inheritance
AML = acute myeloid leukemia; MDS = myelodysplastic syndromes; WAGR = Wilms tumor, aniridia, genitourinary anomalies, mental retardation.
