Although NTRK gene fusions occur in less than 5% of gastrointestinal cancers, it looks like they can be targeted successfully with NTRK inhibitors. In a pooled analysis of three clinical trials, 50% of such patients responded to entrectinib, in an updated analysis presented during the 2020 virtual...
Considered the “guardian of the genome,” TP53 is the most commonly mutated gene in patients with cancer. TP53's normal function is to detect DNA damage and prevent cells from passing this damage on to daughter cells. When TP53 is mutated, the protein made from this gene, called p53, can no longer...
