Discover the importance of HER2 IHC assessment in solid tumors.

HER2 can be overexpressed in many solid tumors beyond gastric and breast¹

That’s why HER2 IHC testing is recommended across multiple tumor types.^2-12 Your role in evaluating the HER2 biomarker further is critical for patient care. We cannot over-express this enough.

The clinical relevance of HER2 positivity (IHC 3+)

HER2 positivity has long been associated with a poor prognosis, including increased recurrence and decreased outcomes across different tumor types^13-18
HER2 is broadly expressed and clinically relevant across solid tumors, including NSCLC, endometrial, cervical, ovarian, bladder, biliary tract, CRC, pancreatic, gastric, and breast cancers^18,19

Prevalence of HER2 alterations across solid tumors^a

^aIndividual tumor prevalence numbers reflect US and ex-US populations. Due to limited testing of IHC in the US, data from a global population have been included.

^bHER2 protein expression is measured using IHC with confirmatory ISH testing in cases of equivocal results.^67,68

^cHER2 (ERBB2) amplification is measured using ISH techniques, including FISH, CISH, and SISH, or by NGS.^50,69

^dHER2 (ERBB2) mutations are detected through sequencing techniques, such as NGS.^50,54

HER2 protein overexpression
(IHC 3+) is distinct from genomic HER2 (ERBB2) alterations

Overview of HER2 overexpression, gene amplification, and gene
mutation^67,68,70,71

Alteration	HER2 protein overexpression	HER2 (ERBB2) gene amplification	HER2 (ERBB2) gene mutation
Definition	Overabundance of HER2 protein on the surface of tumor cells	Elevated number of HER2 gene copies	Activating mutation in the HER2 gene
Testing method	IHC	ISH or NGS^e	NGS^d

There are 3 distinct types of HER2 alteration that may lead to oncogenic activation of the
HER2 pathway: HER2 protein
overexpression, HER2 (ERBB2) gene
amplification, and HER2 (ERBB2) gene
mutation^67,68,70,71
NGS, FISH, and liquid biopsy do not detect HER2 protein overexpression (IHC 3+)^68,70

^eISH is a molecular testing method that detects
HER2 DNA copy number, while NGS detects both
HER2 DNA copy number and/or HER2
mutations.^70,71

HER2 IHC scoring for solid tumor types other than breast cancer

HER2 IHC testing is well established in gastric cancer, and the gastric scoring criteria have been applied to other solid tumor types, including NSCLC, colorectal, and gynecologic tumors^2,7,68,73
ASCO-CAP gastric cancer scoring criteria allow for more staining heterogeneity than ASCO-CAP breast cancer scoring criteria^67,68,74
- For example, gastric cancer scoring criteria define HER2 overexpression using basolateral and lateral membrane staining in addition to circumferential staining

Staining patterns required for IHC 3+ with each set of ASCO-CAP scoring criteria^67,68

HER2 IHC testing recommendations

There are several key considerations in HER2 assay validation beyond the testing guidance for breast and gastric cancers, including which assay scoring system is used⁷⁶

ASCO-CAP gastric cancer scoring criteria may be applied in multiple solid tumor types to determine HER2 IHC status^2,68,73,77

HER2 testing guidance and reporting tools across tumor types

Pathology specialty	Metastatic/advanced tumor type	NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) testing guidance	CAP Biomarker Reporting Template for HER2 testing results	Applicable HER2 IHC scoring criteria
Breast	Breast	IHC, ISH^3,67,78	Breast Biomarker Reporting Template	ASCO–CAP breast scoring criteria^a
Gastrointestinal	Biliary tract	IHC, FISH, NGS^69,79	General IHC Quantitative Biomarkers Template	No universal guideline (ASCO–CAP gastric scoring criteria may be used)
	Gastric/GEJ	IHC, ISH, NGS^5,68,80,81	Gastric HER2 Biomarker Reporting Template	ASCO–CAP gastric scoring criteria^a

	Cervical	IHC, FISH^12,68,73	Gynecologic Biomarker Reporting Template	ASCO–CAP gastric scoring criteria^c

^aCriteria recommended by ASCO-CAP.

^bThere is no consensus on whether breast or gastric cancer scoring criteria should be applied to colorectal cancer. Some clinical trials have utilized ASCO-CAP breast scoring criteria, and others have utilized ASCO-CAP gastric cancer scoring criteria. Laboratory directors are asked to exercise their discretion as to which scoring criteria to apply.⁷⁶

^cCriteria included in CAP reporting template.

^dScoring criteria for anti-HER2 monoclonal antibody/antibody-drug conjugate therapy is currently based on criteria initially applied in gastric carcinoma, which utilizes different scoring criteria than that utilized for breast carcinoma and employs different scoring criteria for small biopsy specimens versus resections.²

HER2 IHC reporting across tumor types

The following CAP biomarker reporting templates include fields for reporting HER2 IHC results^{73,77-79,81-83}:

Breast

Colon and rectum

Lung

Gynecologic

Gastric HER2

Head and neck

For other tumor types, the CAP General IHC Quantitative Biomarkers Template is available.

Access all of the CAP templates listed above

Example of CAP validation guidance for IHC assays in solid tumors outside of breast and gastric cancers^a

Extending a previously validated assay to colorectal cancer⁷⁶

If the laboratory director intends to perform HER2 IHC on colorectal tumors using a previously validated assay and scoring criteria combination, the laboratory director has the discretion to extend the initial validation to colorectal cancer by assessing a representative sample
of colorectal cancer

Validating a new assay in multiple tumor types⁷⁶

If a laboratory is initially validating a new HER2 assay and intends to use the same scoring criteria in breast and colorectal cancers, then both cancer types should be included in the set of 20 positive and 20 negative tissues constituting the validation
- It is not the intent of this recommendation that every assay, scoring criteria, and tumor type combination be subject to the requirement of 20 positive and
  20 cases for each validation

Perform HER2 IHC testing across metastatic solid tumor types

HER2 IHC testing is recommended in NCCN Guidelines® across numerous solid tumor types^2-12
Consider using ASCO-CAP gastric cancer scoring criteria across solid tumor types, outside of breast^2,68,73,77
Due to the biology of the different alterations, NGS, FISH, and liquid biopsy do not detect HER2 protein overexpression (IHC 3+)^68,70
HER2 IHC testing should be performed, regardless of NGS or ISH results, to ensure patients are accurately identified^68,70-72
