Society for Immunotherapy of Cancer 2019, Tempus-authored – Microsatellite instability is a clinically actionable genomic indication for cancer immunotherapy. In microsatellite instability-high (MSI-H) tumors, defects in DNA mismatch repair (MMR) can cause a hypermutated phenotype where alterations accumulate in the repetitive microsatellite regions of DNA. MSI detection is typically performed...

Society for Immunotherapy of Cancer 2019, Tempus-authored — Human leukocyte antigen (HLA) class I proteins are expressed on the surface of all nucleated cells and are vital for immune surveillance. When tumor-specific mutations (neoantigens) are presented on HLA molecules to CD8+ T cells, this recognition can drive immune responses against...

American Society of Hematology 2019, Tempus-authored — Multiple Myeloma (MM) remains a cancer of terminally-differentiated plasma cells that reside predominantly within the bone marrow. Malignant plasma cells are nurtured by a permissive microenvironment that favors tumor progression, drug resistance and disease relapse. Recurrent somatic mutations in hematopoietic stem cells, the...

Nature Biotechnology, Tempus-authored – Genomic analysis of paired tumor–normal samples and clinical data can be used to match patients to cancer therapies or clinical trials. We analyzed 500 patient samples across diverse tumor types using the Tempus xT platform by DNA-seq, RNA-seq and immunological biomarkers. The use of a tumo...

Journal of Pathology Informatics, Tempus-authored – Background: Tumor programmed death-ligand 1 (PD-L1) status is useful in determining which patients may benefit from programmed death-1 (PD-1)/PD-L1 inhibitors. However, little is known about the association between PD-L1 status and tumor histopathological patterns. Using deep learning, we predicted PD-L1 status from hema...

2019 Clingen: Curating the Clinical Genome, Tempus-authored – The ClinGen PTEN Variant Curation Expert Panel (VCEP) provides assessment regarding the pathogenicity of germline PTEN variants with respect to a PTEN Hamartoma Tumor syndrome (MIM+601728) phenotype using PTEN-specific variant classification criteria based on the 2015 ACMG/AMP framework. Of highest priority...

Journal of Clinical Oncology, Tempus-authored – Background: Tumors of unknown origin occur in approximately 5% of newly diagnosed cancers and are difficult to treat without establishing the tissue type from which they derive. Establishing tumor origin guides standard of care treatment for several NCCN targeted therapy guidelines. Leveraging tissue sp...

Journal of Clinical Oncology, Tempus-authored – Background: Anecdotal and early evidence suggest ICIs are being used in patients with advanced malignancies and history of AD, despite such patients being typically excluded from traditional clinical trials. We compared the outcomes of patients with or without AD, all of whom had...

Journal of Clinical Oncology, Tempus-authored – Background: Immune Checkpoint Inhibitors (ICIs) were first approved for the treatment of aNSCLC in 2014, and since this time have seen rapid adoption in the marketplace. We sought to describe the characteristics of patients with aNSCLC receiving ICIs in the real-world, as well as t...

Journal of Clinical Oncology, Tempus-authored – Background: ICI’s have demonstrated significant clinical benefit since the first FDA approval in 2011 of ipilimumab for metastatic melanoma. Five additional ICI therapies have since been approved across several indications. The objectives of this study were to describe the clinical and demograph...
