Ovarian cancer is detectable from peripheral blood using machine learning over T cell repertoires

<p>To see if TCR repertoire obtained from peripheral blood is associated with tumor status, we collected blood samples from 85 women with or without ovarian cancer and produced T cell receptor information. Using machine learning, we stratified, with high success rates, the two groups, thereby associating peripheral blood T cell repertoire with the existence of ovarian cancer tumors.</p>
