Hematologic malignancies in Li-Fraumeni syndrome: A case report.

Li-Fraumeni syndrome (LFS) is a rare syndrome characterized by an increased lifetime risk of cancer development in multiple organ systems, typically caused by de novo or inherited germline pathogenic variants in the tumor suppressor TP53 gene. LFS is more classically associated with solid tumors; however, it is also associated with hematologic malignancies such as therapy-related acute myeloid leukemia (AML). We present the case of a female patient with a strong family and personal history of cancer who presented to our institution with therapy-related AML with next-generation sequencing showing a pathogenic TP53 mutation.

Infiltrating gliomas with FGFR alterations: Histologic features, genetic alterations, and potential clinical implications.

Background: Fibroblast growth factor receptors (FGFRs) are frequently altered in cancers and present a potential therapeutic avenue. However, the type and prevalence of FGFR alterations in infiltrating gliomas (IGs) needs further investigation.

Objective: To understand the prevalence/type of FGFR alterations in IGs.

Differences in Genomic Alterations Between Brain Metastases and Primary Tumors.

Background: Brain metastases (BMs) occur in ∼1/3 of cancer patients and are associated with poor prognosis. Genomic alterations contribute to BM development; however, mutations that predispose and promote BM development are poorly understood.

Objective: To identify differences in genomic alterations between BM and primary tumors.
