Cancer Biomarkers

News on molecular markers used to guide cancer treatment, assess prognosis, or detect relapse.

Qiagen's test detects the most frequently occurring somatic mutations in EGFR in less than four hours using real-time PCR on the Rotor-Gene Q platform.

MSK researchers showed that high TMB may be associated with improved survival across tumor types, but the cut-offs for high and low status will vary based on histology.

Researchers from the PROREPAIR-B study reported that men with germline BRCA2 mutations and prostate cancer had shorter cause-specific survival.

In a small study, melanoma patients with BRAF V600K mutations responded better to immunotherapy while those with V600E mutations had a better response to targeted therapy.

In a letter to CMS, AMP made a case for crosswalking existing CPT codes for BRCA1/2 testing to codes that more accurately reflect the work required to analyze these genes.

The test is now approved as a CDx for advanced ovarian cancer patients considering Lynparza as a first-line maintenance treatment.

The draft guidelines have intrigued industry players interested in pursuing labeling that would allow their CDx to direct treatment for a class of drugs instead of one drug.

The researchers also reported that combining an ER-directed therapy with an irreversible HER2 kinase inhibitor could overcome resistance.

New data on Kadcyla and Tecentriq will help doctors further refine precision medicine options for breast cancer patients with unmet needs.

The firms will begin a prospective lung cancer study using Biocartis' Idylla EGFR mutation test in European countries, including Belgium, France, Germany, and Italy.
