    Helping Reduce Diagnostic Uncertainty in Metastatic Cancer

    Over 100,000 metastatic cancer cases per year have some degree of diagnostic ambiguity.1-3 CancerTYPE ID is a gene expression assay that helps physicians achieve a definitive diagnosis for metastatic patients when the tumor’s origin is uncertain. The test provides increased clarity by helping resolve the following diagnostic dilemmas that impact treatment decisions:

    • Unclear/differential diagnoses 
    • Poorly-differentiated tumors 
    • Cancers of Unknown Primary (CUP)
    • New cancer type vs. recurrence

    • Unusual presentations

    A proprietary gene expression assay for cancer classification.

    CancerTYPE ID uses real-time RT-PCR to measure the expression of 92-genes in the patient's tumor and classifies the tumor by matching the gene expression pattern to a database of over 2,000 known tumor types and subtypes. Using this technology, CancerTYPE ID can differentiate between 50 different tumor types and subtypes, covering >95% of all solid tumors based on incidence. The test reports a molecular diagnosis of the cancer type with the highest probability match, as well as a list of tumor types that may be ruled out with 95% confidence.4

    Achieving a definitive diagnosis is fundamental to guide appropriate treatment in metastatic cancer.

    Determining a single cancer type diagnosis is essential for an oncologist’s ability to effectively treat his or her patient. While IHC is the standard of care method used to establish an initial pathologic diagnosis, metastatic disease often poses diagnostic challenges, resulting in about 1 out of 10 metastatic patients whose results remain inconclusive after standard diagnostic workup.5-8 For these difficult-to-diagnose metastatic cases, CancerTYPE ID provides important tumor type information to help physicians gain diagnostic clarity.


    Although recent studies have investigated whether molecular alterations alone are sufficient to direct treatment, results have demonstrated limited actionability of these markers. In fact, in studies with 1,000 patients, only 5-13% of cases had a clinically actionable genomic alteration and received a matched therapy, and efficacy of treatments based on these alterations alone has been shown to be inconsistent across different tumor types.9-11 Thus, a definitive diagnosis of the tumor type remains a critical first step for appropriate treatment.

    "The most important aspect to treating cancer is to know what type of tumor we are dealing with."

    "Once we know this, additional testing like Next Gen Sequencing can help further stratify treatment approaches, but the fundamental piece of information we need to start with is where the tumor is coming from."

    Supported by Extensive Validation

    CancerTYPE ID is the only molecular cancer classifier that has demonstrated improved patient outcomes.


    Validated Accuracy12


    Tumor Type Identified13


    Improved Survival13

    • CancerTYPE ID has been rigorously validated, demonstrating 87% accuracy in a multi-institutional validation study led by three Centers of Excellence (UCLA, Mayo Clinic, and MGH).12

    • In a prospective clinical trial led by the Sarah Cannon Research Institute, CancerTYPE ID identified a primary tumor type in 98% of cases. Furthermore, treatment based on the CancerTYPE ID result improved overall survival by 37% vs. empiric therapy.13

    • A study comparing CancerTYPE ID to standard of care IHC also showed that when more than 7-9 stains were required for a diagnosis, the accuracy of IHC fell below 50%, while CancerTYPE ID maintained significantly higher performance, and therefore may provide a tissue-sparing approach to establish the tumor type in these challenging cases.5

    Impact on Clinical Decision-Making and Treatment Options


    Treatment Decisions Changed14-15


    Classified as Immunotherapy Eligible16

    • In a clinical utility study, CancerTYPE ID changed physician treatment decisions in approximately 50% of cases. In cases with two or more suspected sites, CancerTYPE ID identified a primary tumor type not previously considered in about 1 out of 4 patients.14-15
    • study of 24,426 cases from a large-scale research database of CancerTYPE ID clinical cases demonstrated the role of CancerTYPE ID in identifying CUP patients who may be eligible for immunotherapy based on tumor type determination.16 Results revealed 38% of cases classified by CancerTYPE ID were predicted to have an immunotherapy-eligible tumor type (N=9,350).16

    Intended Use: CancerTYPE ID Intended Use and Limitations CancerTYPE ID is indicated for use in tumor specimens from patients diagnosed with malignant disease and is intended to aid in the classification of the tissue of origin and tumor subtype in conjunction with standard clinical and pathological assessment by a qualified physician. CancerTYPE ID is not intended to predict patient survival benefit, treatment efficacy or to distinguish between benign versus malignant lesions. Tumor types not included in the CancerTYPE ID reference database may exhibit RNA expression patterns that are similar to RNA expression patterns within the reference database. This test was developed and performance characteristics have been determined by Biotheranostics, Inc. It has not been cleared or approved by the U.S. Food and Drug Administration. This test is used for clinical purposes. It should not be regarded as investigational or for research. How this information is used to guide patient care is the responsibility of the physician. Biotheranostics is certified under the Clinical Laboratory Improvement Amendments of 1988 as qualified to perform high-complexity clinical laboratory testing.
