Biomarkers

A biomarker entry is an identity record — what is measured, by which assay family, the NCIt concept it maps to and the gene it is anchored to. Every link to cancers, drugs, approvals and trials is derived at query time from curated evidence and registries; nothing on this page grades clinical utility or states a threshold of its own.

Counts are computed over ingested sources only (CIViC, ClinicalTrials.gov, openFDA, Health Canada, PubMed) and say nothing about biomarkers or links that are not yet ingested. A trial counted here tests a linked drug in a linked cancer; it does not necessarily select patients on the biomarker.
