What is HER2 Testing?

HER2 Testing is a laboratory test performed on breast cancer cells to assess whether they overexpress the HER2 protein (also known as Human Epidermal Growth Factor Receptor 2). The laboratory procedure forms an integral part of the diagnosis, staging, treatment, and management of breast cancer patients.

HER2 is a protein responsible for the regulation of cell proliferation and repair within the body. In some cases of breast cancer, the HER2 gene gets amplified, resulting in the overproduction of HER2 protein, which causes rapid tumor growth. Such cancers are referred to as HER2-positive breast cancers.

In recent times, tremendous improvements in molecular diagnosis, targeted oncology treatments, and advances in precision oncology treatments have led to better outcomes for women suffering from HER2-positive breast cancer. HER2 Testing is vital in identifying patients who will benefit from HER2-specific treatments that kill cancer cells without harming surrounding healthy cells.

Advanced Cancer Center of Excellence provides HER2 Testing services in combination with other procedures, including advanced medical imaging, molecular profiling, pathology, multidisciplinary oncology, treatment planning, rehabilitation, and survivorship care.

What is the role of HER2?

HER2 is the medical term used for Human Epidermal Growth Factor Receptor 2.

It is a protein located on the surface of some normal breast cells that regulates:

• Cell proliferation
• Cell division
• Tissue healing

In cases where breast cancer forms, the HER2 gene is amplified or overexpressed, leading to rapid cell division and growth.

What is HER2-Positive Breast Cancer?

HER2-positive breast cancer refers to cancers that produce excess HER2 proteins.

They tend to be:

• Aggressive
• Fast-growing
• High-risk of spreading
• More likely to recur without treatment

But thanks to advanced drugs, the outcome of treatment has improved significantly for HER2-positive breast cancer patients.

What is the importance of HER2 Testing?

HER2 Testing is one of the critical laboratory tests in diagnosing and staging breast cancer.

This test can help the doctor:

• Diagnose HER2-positive tumors
• Calculate targeted therapy
• Estimate the response to treatment.
• Create an individualized treatment plan.
• Conclude on prognosis and recurrence risks.

HER2 Testing is regarded as a standard part of breast cancer diagnosis.

When do Doctors Perform HER2 Testing?

HER2 Testing is normally done on breast tissue that is collected through:

• Core needle biopsy
• Breast biopsy surgery
• Lumpectomy
• Mastectomy specimens

The test may also be performed on:

• Recurrent breast cancer
• Metastatic breast cancer
• Cancers with evolving biology

What are the Methods of HER2 Testing?

Several modern laboratory methods are used to determine HER2 status.

Immunohistochemistry (IHC)

IHC estimates HER2 protein expression in cancer cells.

Interpretation of the results includes:

• 0 or 1+ score: HER2-negative
• 2+: Borderline/Equivocal result
• 3+: HER2-positive

A borderline score needs further testing.

Fluorescence in Situ Hybridization (FISH)

FISH is the method used to identify HER2 gene amplification in cancer cells.

It is highly reliable and may be performed if the IHC results are ambiguous.

Other Modern Molecular Methods

The advanced laboratories employ the following methods:

• Dual ISH method
• Chromogenic ISH method
• Molecular-genomic method

They help in providing better diagnoses and treatment.

How are HER2 Testing Results Interpreted?

The HER2 test results enable classification of the breast cancer into:

• HER2-positive
• HER2-negative
• HER2-low (in certain modern classifications)

This information allows doctors to:

• Choose the optimal treatment.
• Provide the prognosis
• Plan targeted therapy

What are the Characteristics of HER2-Positive Breast Cancers?

HER2-positive breast cancers may:

• Rapidly grow
• Be highly aggressive
• It spreads quickly if left untreated.

However, with advanced targeted therapies, many patients nowadays achieve favorable outcomes.

What is HER2-Negative Breast Cancer?

Cancer types that are HER2-negative have no overexpression of the HER2 protein.

Therapies that can be used in such cancers include:

• Hormonal therapies
• Chemotherapies
• Immunotherapy
• Other targeted therapies

How does HER2 Testing enable Personalized Cancer Treatment?

HER2 Testing forms an integral part of precision oncology.

This test helps the doctors in ways that:

• Personalization of treatment
• Selection of appropriate drugs
• Determination of drug response

Personalized cancer treatment helps save time and money and can even increase survival rates in many cases.

What are HER2-Targeted Therapies for Breast Cancer?

Individuals diagnosed with HER2-positive breast cancer can benefit from special HER2-targeted therapies.

Treatment options for HER2-positive breast cancer are:

• Monoclonal antibodies
• Antibody drug conjugate
• HER2-targeted tyrosine kinase inhibitors

Such therapies have been developed to target cancer cells only, without affecting normal tissues.

How is HER2 Testing used Across Different Stages of Breast Cancer?

HER2 testing is important in all stages of breast cancer, including:

• Early-stage breast cancer
• Locally advanced breast cancer
• Metastatic breast cancer
• Recurrent breast cancer

The results of HER2 testing help in planning the entire course of treatment.

What Additional Laboratory Tests are Performed on Breast Tissue?

Breast tissue may be tested through additional tests, such as:

• Hormone receptor testing (estrogen/progesterone)
• Ki-67 proliferation
• Molecular profiling

What is Hormone Receptor Testing in Breast Cancer?

Hormone receptor testing can show whether tumors are sensitive to:

• Estrogen
• Progesterone

Testing helps determine whether hormone therapy is appropriate.

What role does Molecular Profiling play in Breast Cancer?

Molecular profiling tests can be used for:

• Recurrent risk prediction
• Therapy choice guidance
• Oncological personalization

How does HER2 Testing help in Breast Cancer Staging?

Results of Her2 Testing help in:

• Classification of tumor
• Prognostic factors
• Treatment planning

In combination with radiological and pathological evaluation, Her2 Testing is useful for cancer staging.

What Advanced Techniques are used in Breast Cancer Diagnostics and Therapy?

Technologies used in oncology have changed modern approaches to breast cancer diagnosis and treatment.

• Digital Pathology & Computer-assisted Diagnostics: Current pathology techniques used in diagnostics include improvements to HER2 testing, tissue interpretation, proper diagnosis, and reporting accuracy. Algorithms may be able to improve image interpretations.
• Personalized Molecular Medicine: Molecular diagnostic tools enable doctors to choose targeted drugs, evaluate treatment responsiveness, customize therapy approach, and conduct better prognoses.
• High Resolution Breast Imaging: Modern mammography, ultrasounds, MRIs, and PET-CT scanning enhance tumors early detection, tumors localization, and cancer staging procedure.
• Image-guided Biopsy Technology: Modern biopsy systems facilitate tissue sampling, diagnosis, and patient comfort.
• Radiation therapy-Precision: Recent radiotherapy includes Intensity Modulated Radiotherapy (IMRT) and Image-Guided Radiotherapy (IGRT). It will increase precision and minimize unnecessary exposure to other tissues.
