In a separate post, I already mentioned The Pathwork® Tissue of Origin Test.
It is interesting to know that Stanford University School of Medicine is investigating an investigational study of the this genomics-based diagnostic test for hard-to-identify tumors — The Pathwork® Tissue of Origin Test.
The new test uses advanced genomics-based technology to help physicians determine a tumor’s origin in order to optimize cancer-specific treatment.
The study will evaluate the test’s ability to impact diagnosis for cancer patients with hard-to-identify tumors, with test samples processed at the Stanford University School of Medicine’s laboratory.
According to Dr. Iris Schrijver, Director of Molecular Pathology at Stanford …read more

A product of Pathwork Diagnostics, The Pathwork® Tissue of Origin Test is designed to increase diagnostic certainty for hard-to-identify tumors.
The Pathwork® Tissue of Origin Test measures the expression of more than 1500 genes present in a tissue sample and generates the tumor’s gene expression profile. This profile is then compared to those of 15 known tissues, representing more than 60 morphologies. An objective, probability-based Similarity Score is provided for each of the 15 potential tissue types, enabling each tissue type to be ruled in or ruled out.
