• A novel, more sensitive test for HER2 protein in lung cancer tissues has been developed, potentially expanding the number of patients eligible for trastuzumab deruxtecan (T-DXd).
• The new assay detected elevated HER2 levels in 63% of lung cancer samples, a significant increase compared to the 2% identified by current standard tests.
• This advancement could lead to more personalized treatment approaches, matching patients with targeted therapies based on their unique biomarker profiles.
• Researchers are working on similar tests for other cancer types, paving the way for broader application of biomarker-driven cancer treatments.
