Prognostic Markers for Breast Cancer: What Patients Should Know
By
Breast cancer is one of the most common cancers affecting women across the globe. However, the good news is that early detection and advances in treatment have crucially improved the survival rates. The key area of treating breast cancer progress lies in understanding its prognostic markers, such as biological indicators that help doctors predict how a breast cancer might behave and respond to treatment. In simpler terms, the prognostic markers are the same as the ‘clues’ that are hidden within the cancer cells that help make personalized treatment decisions.
In this blog, we’ll discover more about how these markers empower patients to understand their diagnosis better and take a proactive role in their cancer care.
Prognostic Markers for Breast Cancer
A prognostic marker for breast cancer is a crucial measurable biological characteristic that provides significant information about the overlook of a breast cancer patient, which include the recurrence of cancer or death, independent of specific treatment or therapy.
These cans helps with:
- How aggressive the cancer appears
- The chance of the cancer recurrence or the overall survival
Here are some of the examples: tumor grade, size, lymph node status in breast cancer, all of these considered as prognostic markers for breast cancer.
Key prognostic markers in Breast Cancer
Here are some of the most commonly used prognostic markers in breast cancer.
These may include:
Hormone Receptor Status:
What it is: These tests used to check if the breast cancer cells have proteins called estrogen receptors (ER) and progesterone receptors (PR).
Why it matters: Cancer cells with these types of receptors can use hormones to grow. This is commonly known as hormone-receptor positive breast cancer, which tends to slow the growth and these can be often treated with hormone therapy.
HER2 (Human Epidermal Growth Factor Receptor 2):
What it is: This is a protein that can be often present in high amounts on cancer cells.
Why it matters: While HER2 positive breast cancers are often found to be aggressive, they are also responsible for targeted therapies such as trastuzumab (Herceptin).
Ki-67 Index:
What it is: This is a type of test that is used to measure the percentage of cancer cells that are actively dividing as well.
Why it matters: A high Ki-67 score usually indicates a quickly growing, more aggressive type of cancer, while a low score suggests a slower growth and better treatment prognosis.
Tumor grade and Stage:
What it is: This often helps to indicate how abnormal the cancer cells appear under a microscope.
Why it matters: How far the cancer cells has spread in the body
Genomic Tests (eg: Oncotype DX, MammaPrint)
What it is: These types of advanced tests help to analyse the activity of a certain gene in the tumor.
Why it matters: These tests are often used to provide more accurate risk of these cancers recurring and generally help breast cancer specialists decide whether chemotherapy is beneficial for a specific patient.
Why do prognostic markers matter for breast cancer patients?
Understanding these types of markers helps breast cancer patients and their caregivers on their breast cancer treatment journey.
Here is why prognostic markers matter most for breast cancer patients; these may include:
- More personalized treatment plans designed for their cancer type: While prognostic markers like PR, ER, and HER2 status allow the oncologists to design a personalised treatment plan especially for a specific patient.
- Avoid overtreatment when it's not necessary: These help to identify patients at low risk of recurrence, how doctors avoid aggressive treatments like chemotherapy, which can also have serious side effects.
- Gain insights into long-term treatment outcomes and recurrence risks: These help to identify and predict the chance of cancer recurrence or even death, allowing patients to understand the long-term prognosis of the patient.
- Empowered and informed throughout their cancer journey: Understanding the specific markers for breast cancer that help patients and their families to feel more informed and get more control of their treatment decisions.
The future of breast cancer prognosis
The science of breast cancer prognosis is evolving rapidly in today’s time. New markers, molecular profiling, and AI-based prediction tools have been used in cancer treatments. It helps breast cancer specialists make even more precise treatment decisions and treatment plans. The main goal is to make cancer treatments more personalized, effective and compassionate for every patient.
