Recent biomarker studies aimed to increase the prognostic and predictive value with the inclusion of AR‐V7 expression in circulating tumour cell (CTC), high circulating tumour content and many genetic aberrations involving AR, TP53, the PI3K/AKT pathway and homologous recombination repair [4, 5, 6, 26, 27]. Here, TP53 is linked to neoplasm.
