NTRK1 expression exhibited a significant association with age at diagnosis, tumour location, pathological tumour (T) stage, pathological metastasis (M) stage, microsatellite instability status, molecular subtype according to the epithelial (CIN)/hypermutated (MSI)/mesenchymal (genome-stable, GS) scheme, BRAF mutation status, fraction genome altered (FGA) state and tumour mutational burden (TMB). The gene discussed is NTRK1; the disease is neoplasm.
