Spanish National Cancer Research Centre (CNIO) scientists have developed a genomic test that predicts which patients will not respond to three common chemotherapy types, potentially sparing 20-50% of cancer patients from ineffective treatment and severe side effects.
The test analyzes chromosomal instability signatures in tumor DNA to identify resistance patterns for platinum-based, taxane, and anthracycline chemotherapies across multiple cancer types including breast, prostate, ovarian, and sarcoma cancers.
Validation studies using data from 840 patients demonstrated the test's effectiveness, with clinical trials planned for 2026 following funding from the Spanish Ministry for Digital Transformation and Public Service.
The technology, developed in collaboration with University of Cambridge and startup Tailor Bio, represents a breakthrough in precision medicine by transforming conventional chemotherapies into targeted treatments.
