Three secondary malignant neoplasms in a childhood cancer survivor positive for nibrin gene mutation – a case report and literature review

Abstract

Childhood cancer survivors often develop subsequent neoplasms secondary to radio- (RT) or chemotherapy (CHT). Risk factors for the secondary tumors are the female gender, older age at diagnosis, Hodgkin’s lymphoma treatment and the use of RT. The cumulative incidence of the second malignant neoplasm, excluding non-melanoma skin cancer, 30 years after the childhood cancer diagnosis is around 8% [1]. We present the case of a patient who developed three independent malignancies following radical treatment of nephroblastoma (Wilms’ tumor; WT) in childhood, found at the age of 53 to be a carrier of the 657_661delACAAA (p. Lys219fs) mutation in the 6/16 exon of the nibrin coding gene (NBN).
