MI Cancer Seek Tumor Profiling
MI Cancer Seek
MI Cancer Seek™ is the first and only simultaneous Whole Exome Sequencing (WES) and Whole Transcriptome Sequencing (WTS)-based assay with FDA-approved CDx indications for molecular profiling of solid tumors. MI Cancer Seek is available for adults and pediatric patients, ages 1-22.
FDA-Approved CDx Indications and Tumor Profiling
MI Cancer Seek is a next-generation sequencing (NGS) based in vitro diagnostic device using total nucleic acid (TNA) isolated from formalin-fixed paraffin embedded (FFPE) tumor tissue specimens for the detection of SNVs, InDels, MSI, TMB in patients with previously diagnosed solid tumors, and CNA in one gene in patients with breast cancer. MI Cancer Seek is intended as a companion diagnostic to identify patients who may benefit from treatment with the targeted therapies listed in the Companion Diagnostic Indications table, in accordance with the approved therapeutic product labeling.
Additional Services
Beyond the MI Cancer Seek FDA-approved indications, additional sequencing-based features are reported.
- DNA: gLOH, HRD, HLA Genotype, Chromosomal Alterations, Viruses (HPV 16 & 18, EBV, MCPyV)
- RNA: Expression, Fusions, Variant Transcripts
- AI Signatures: Caris GPSai™, Caris FOLFIRSTai™

Intended Use
MI Cancer Seek is a next-generation sequencing (NGS) based in vitro diagnostic (IVD) device using total nucleic acid (TNA) isolated from formalin-fixed paraffin-embedded (FFPE) tumor tissue specimens for the detection of single nucleotide variants (SNVs) and insertions and deletions (indels) in 228 genes, microsatellite instability (MSI), tumor mutational burden (TMB) in patients with previously diagnosed solid tumors, and copy number amplification (CNA) in one gene in patients with breast cancer.
MI Cancer Seek is intended as a companion diagnostic to identify patients who may benefit from treatment with the targeted therapies listed in the Companion Diagnostic Indications table, in accordance with the approved therapeutic product labeling.
Additionally, MI Cancer Seek is intended to provide tumor mutational profiling to be used by qualified healthcare professionals in accordance with professional oncology guidelines for cancer patients with previously diagnosed solid malignant neoplasms. Genomic findings other than those listed in the Companion Diagnostic Indications table are not prescriptive or conclusive for labeled use of any specific therapeutic product.
Enhance Molecular Insights with Comprehensive Professional Services
MI Cancer Seek is a single assay that analyzes total nucleic acids for both DNA and RNA. Typically, DNA and RNA analysis by NGS requires two separate testing processes, which may require more tissue and more time. By combining WES and WTS into one assay, however, MI Cancer Seek provides a comprehensive molecular blueprint that saves tissue without compromising results.
