What is the HER2 Amplification Test?

The HER2 amplification test is a critical diagnostic tool used in the world of oncology. HER2, or Human Epidermal Growth Factor Receptor 2, is a protein that can play a role in the development of certain types of cancer. When a cancer cell has too many copies of the HER2 gene, it is said to be "HER2-positive," which can influence the treatment approach. Understanding the specifics of the HER2 amplification test, including the different types of tests available, what they measure, how they are performed, and what the results mean, is crucial for patients and healthcare professionals alike.

Different Types of HER2 Tests

There are three primary types of HER2 tests used to determine HER2 status:

• Immunohistochemistry (IHC): Immunohistochemistry test measures the amount of HER2 protein on the surface of the cells in the cancer tissue. The results are given a score of 0 to 3+, with 3+ indicating a high level of HER2.
• Fluorescence In Situ Hybridization (FISH): FISH is used to count the number of HER2 genes in cancer cells. It's a more precise test and is often used to confirm IHC results.
• Chromogenic In Situ Hybridization (CISH): Similar to FISH, CISH also measures the number of HER2 genes in cells but uses a chromogenic substrate instead of fluorescence, making it easier to see under a regular microscope.

How the Test Is Performed

The HER2 amplification tests are performed on a biopsy or surgery sample of the tumor tissue. After the sample is prepared and placed on slides, it is then analyzed using one of the methods mentioned above to determine the HER2 status.

Interpreting Test Results

Understanding the results of HER2 tests is a key step in planning cancer treatment. A positive result indicates an overexpression of the HER2 protein or an amplification of the HER2 gene, suggesting that HER2-targeted therapies may be effective. Negative results mean that HER2 is not overexpressed, and other treatment options would be considered. Equivocal results, where the test doesn't clearly show if the cancer is HER2-positive or --negative, may require additional testing.

It's important to note that the results of HER2 tests are just one piece of the puzzle in the overall treatment plan for cancer patients. Consultation with an oncologist and a personalized approach to treatment are key to achieving the best outcomes.

Why It Matters
