Customer insights

“In the rapidly changing world of cancer care and precision medicine, Tempus is the established leader. They provide rapid, accurate results while also continuing to develop innovative strategies to improve patient outcomes.

“Breast cancer care has involved use of biomarkers for years in order to determine appropriate therapy. Genomic information has now been added to the list of crucial biomarkers needed to know how to treat metastatic breast cancer patients with the approval of targeted therapy for BRCA and PIK3CA mutations. Having this information also gives a patient the best opportunity to consider one of numerous biomarker driven clinical trials. These options allow as personalized an approach to treatment as possible and I have no doubt that genomic data will continue to transform the way patients are treated as our field moves forward.” – Megan Kruse, MD, Cleveland Clinic
