Genetic variants linked to moderate-to-severe asthma susceptibility

A genome-wide association study has identified novel genetic variants associated with the risk of developing moderate-to-severe asthma, a substantial proportion of which are also associated with mild asthma susceptibility.

Persistent mutations post-transplant predict MDS disease progression

Persistent disease-associated mutations detected in the bone marrow 30 days after stem cell transplantation are associated with an increased risk for disease progression among patients with myelodysplastic syndrome, research shows.

Broad-based genomic screening benefits questioned for advanced NSCLC

Most patients being treated in the community setting for advanced nonsquamous non-small-cell lung cancer do not benefit from the use of broad-based genomic sequencing, suggests a study comparing this approach with routine testing for only epidermal growth factor receptor and anaplastic lymphoma kinase alterations.

Molecular mechanisms of acquired osimertinib resistance explored

An analysis of patients with T790M-positive, advanced non-small-cell lung cancer who developed resistance to osimertinib points to heterogeneous underlying molecular mechanisms.

TGFB1 gene key determinant of breast fibrosis risk

Carriers of the C−509T allele in the transforming growth factor ß 1 gene have a significantly increased risk for late breast fibrosis following breast-conserving surgery and whole-breast irradiation for stage 0 to IIA breast cancer, researchers report.

Matching treatment to molecular alterations in tumors has an IMPACT on survival

Apostolia Tsimberidou discusses the findings of the IMPACT study, looking at the survival benefits of matching targeted treatments to the genetic alterations of tumors across multiple cancer types (7:56).

Concomitant mutations linked to poorer response in EGFR mutation-positive NSCLC

In patients with epidermal growth factor receptor-mutated non-small-cell lung cancer, the presence of concomitant mutations in other cancer-related genes is associated with worse outcomes in response to EGFR tyrosine kinase inhibitors, Chinese research suggests.

Molecular minimal residual disease predicts poor outcome in AML

The presence of molecular minimal residual disease, identified by next-generation targeted sequencing, is associated with a significantly increased risk for relapse or death in patients with acute myeloid leukemia, study findings indicate.

Telephone disclosure may be a valid option for revealing cancer genetic test results

For individuals who have undergone germline genetic testing, receiving the results via telephone could be a valid alternative to in-person disclosure, trial findings suggest.
