Women who inherit a BRCA1 or BRCA2 mutation have an increased risk of breast cancer. Preliminary evidence suggests they may also have defects in bone marrow function. To test this hypothesis, we conducted a multicenter, retrospective, matched cohort study, comparing women with localized breast cancer requiring cytotoxic chemotherapy who carried an inherited BRCA1 or BRCA2 mutation to similar wild-type patients treated between 1995 and 2017 and matched based on age, race, site, and chemotherapy regimen.

Comprehensive genomic cancer risk assessment (GCRA) helps patients, family members, and providers make informed choices about cancer screening, surgical and chemotherapeutic risk reduction, and genetically targeted cancer therapies. The increasing availability of multigene panel tests for clinical applications allows testing of well-defined high-risk genes, as well as moderate-risk genes, for which the penetrance and spectrum of cancer risk are less well characterized. Moderate-risk genes are defined as genes that, when altered by a pathogenic variant, confer a 2 to fivefold relative risk of cancer.

Next-generation sequencing (NGS)-based targeted gene capture panels are used to profile hematopoietic malignancies to guide prognostication and treatment decisions. Because these panels include genes associated with hereditary hematopoietic malignancies (HHMs), we hypothesized that these panels could identify pathogenic germ line variants in malignant cells, thereby identifying patients at risk for HHMs. In total, pathogenic or likely pathogenic variants in , , , , , , or were identified in 74 (21%) of 360 patients.

Patients with inherited bone marrow failure syndromes (IBMFSs) classically present with specific patterns of cytopenias along with congenital anomalies and/or other physical features that are often recognizable early in life. However, increasing application of genomic sequencing and clinical awareness of subtle disease presentations have led to the recognition of IBMFS in pediatric and adult populations more frequently than previously realized, such as those with early onset myelodysplastic syndrome (MDS). Given the well-defined differences in clinical management needs and outcomes for aplastic anemia, acute myeloid leukemia, and MDS in patients with an IBMFS vs those occurring sporadically, as well as nonhematologic comorbidities in patients with IBMFSs, it is critical for hematologists to understand how to approach screening for the currently known IBMFSs.

Anaplastic lymphoma kinase (ALK) fusion positive non-small cell lung cancer (NSCLC) is a relatively novel molecular subtype in lung cancer. ALK targeted therapies such as crizotinib increase survival benefit in this patient population. However, further understanding of the disease subtype including patterns of metastasis and pathways of treatment resistance are needed.

The familial myelodysplastic (MDS)/acute leukemia (AL) predisposition syndromes are inherited disorders that lead to significantly increased lifetime risks of MDS and AL development. At present, four recognized syndromes have Clinical Laboratory Improvement Amendments--certified testing for their respective germ-line mutations: telomere biology disorders due to mutation of TERC or TERT, familial acute myeloid leukemia (AML) with mutated CEBPA, familial MDS/AML with mutated GATA2, and familial platelet disorder with propensity to myeloid malignancy. These disorders are heterogeneous with regard to their causative genetic mutations, clinical presentation, and progression to MDS/AL.
