The Pathwork Tissue of Origin Test has been extensively evaluated in multiple independent studies involving more than 1,100 patient specimens, including large validation studies published in the Journal of Clinical Oncology and the Journal of Molecular Diagnostics.
A retrospective study of 111 cases from 66 academic and community oncology practices illustrates the use of the test in management of cancer patients. Over two thirds of the cases reviewed showed cancer management changed after the Pathwork Tissue of Origin Test result was received. The majority of the oncologists identified the Tissue of Origin Test results as influencing the decision to make a change in therapy.
