Immunohistochemistry Testing

Optional IHC Add-On for Solid Tumor Profile Plus™

Enhance Solid Tumor Profile Plus™ with optional immunohistochemistry testing for PD-L1, FOLR1, CLDN18, and MET, adding clinically relevant protein expression insights to comprehensive DNA and RNA molecular profiling.

IHC Testing

Overview

IHC Testing

The IHC Add-On for Solid Tumor Profile Plus™ expands comprehensive molecular profiling with immunohistochemistry testing for PD-L1, FOLR1, CLDN18, and MET. This additional layer of analysis helps identify clinically relevant biomarkers that may support treatment selection, including eligibility assessment for immunotherapies and targeted therapies in appropriate patients. Combined with the broad DNA and RNA capabilities of Solid Tumor Profile Plus™, this add-on provides a more complete view of tumor biology and helps physicians make more informed precision oncology decisions.

Short Description

Available as an optional add-on to Solid Tumor Profile Plus™, this IHC panel adds biomarker-specific protein expression analysis for PD-L1, FOLR1, CLDN18, and MET. It is designed to complement genomic and transcriptomic profiling with additional actionable information that can support therapy selection and personalized treatment planning.

The IHC Add-On for Solid Tumor Profile Plus™ provides immunohistochemical assessment of PD-L1, FOLR1, CLDN18, and MET in conjunction with comprehensive DNA and RNA profiling. This integrated approach supports correlation of protein expression with underlying genomic and transcriptomic findings, allowing a more complete characterization of tumor biology. In appropriate clinical contexts, these biomarkers may contribute additional information relevant to therapeutic stratification, including consideration of immunotherapy and targeted treatment options.

Features - Recommendations

The test covers >400 DNA genes and >1600 RNA genes.

Sensitivity is 3% for non-hotspot and 1% for hotspots.  It is at 0.001 for cases with prior Hx. 
Turn Around Time:  7-10 Days
Targeted transcriptome sequencing can also detect:

PD-L1 – can identify patients who would be candidates for pembrolizumab (Keytruda™), nivolumab (Opdivo), atezolizumab (Tencentriq) and other immunotherapies

  • PD-L1 is a protein that is overexpressed in many types of cancer  and is used as a biomarker to determine eligibility for certain immunotherapies.

 

FOLR1 – can identify patients who would be candidates for mirvetuximab soravtansine (Elahere™) 

  • FOLR1 is a folate receptor that is overexpressed in some tumors and can be targeted with folate-based drugs. By adding IHC testing for these biomarkers, GTC can provide more personalized treatment options for cancer patients based on their specific tumor characteristics.

 

CLDN.18 – can identify patients who would be candidates for zolbetuximab (Vyloy™)

  • CLDN18.2 gene is an emerging biomarker in gastric and GEJ cancers and helps predict the likelihood of response to targeted therapy.


MET IHC can identify patients with non-small cell lung cancer (NSCLC) who may be eligible for the targeted therapy telisotuzumab vedotin-tllv (EMRELIS™)
