Stage Vs Grade In GI Cancers & Why Are They Important In Treatment?

Cancer diagnosis involves a complex interplay of multiple factors. Two critical factors in this diagnostic puzzle are the stage and grade of the cancer. While they may sound similar, they provide distinct and crucial information about the disease. But how exactly do these two factors differ, and how do they influence cancer treatment? 

Let’s dive deeper to find out.

Types of Cancer: The Starting Point

Before delving into the concepts of stage and grade, it’s crucial to identify the type of cancer present. This identification is primarily achieved through a biopsy, a medical test involving the extraction of sample cells or tissues for examination.

In the case of cancer, there are several types that can be diagnosed through a biopsy, including:

1.   Squamous Cell Carcinoma: A type of skin cancer that begins in the squamous cells.
2.   Adenocarcinoma: Cancer that forms in mucus-secreting glands throughout the body. It’s commonly seen in cancers of the lung, prostate, colon, and breast.
3.   Gastrointestinal Stromal Tumor (GIST): These are rare tumors that start in special cells in the wall of the gastrointestinal tract, also known as the digestive tract.
4.   Neuroendocrine Tumor: A rare kind of tumor that arises from the specialized body cells called neuroendocrine cells.

Cancer Grading: Peering through the Microscope

When it comes to cancer, the devil is often in the details, and those details are brought to life under the microscope. The grade of cancer gives us an inside look into how these rogue cells stack up against their normal counterparts. In essence, it’s all about observing the changes in these cells and figuring out how quickly they might be gearing up to spread.

To get a clearer picture, let’s break it down:

•       Low-grade cancer: Think of this as the tortoise in the race. It closely resembles normal cells, and its growth and spreading pace is comparatively slow. It’s the cancer equivalent of a “slow and steady” strategy.
• High-grade cancer: This is the hare in our story. High-grade cancer cells can look drastically different from normal cells, hinting that they are likely to spread much faster. It’s an unsettling indication of a possible “fast and furious” approach by these cells.

The Cancer Stage: The Bigger Picture

While the grade gives us a microscopic peek into the cancer cells, the stage takes us on a tour of the bigger picture. It shows us how far cancer has decided to travel within a person’s body, telling us whether the disease has decided to stay put or go sightseeing to other organs.

Staging isn’t just for our curiosity; it’s a crucial tool that helps us plan the treatment strategy and predict how the journey might unfold for the patient. To make it simpler, we use a combination of letters and numbers like Stage 3B. This is based on the TNM system, where:

•       ‘T’ stands for the size of the primary Tumor.
•       ‘N’ checks for the involvement of lymph Nodes.
•       ‘M’ notes any distant Metastasis or spread to other parts of the body.

Decoding the stage and grade of cancer isn’t just a medical procedure; it’s a way to understand the narrative of the disease, predicting its plot twists, and planning our counter-strategy accordingly.

In general, high grade cancers are usually identified at a higher stage and low grade cancers at a lower stage. However, various permutations and combinations between grade and stage are possible.

How Stage and Grade Influence Cancer Treatment?

The stage and grade of cancer are essential determinants of the treatment pathway. For instance, early-stage stomach or colon  cancer with a low grade could potentially be treated endoscopically, meaning through the use of an endoscope—a flexible tube with a light and camera attached to it.

However, if the early-stage cancer is high-grade, implying a faster growth rate and more changes in the cells, higher risk of spread to nodes, more aggressive treatment, such as surgery, may be required. The more advanced the stage and higher the grade, the more comprehensive and aggressive the treatment generally needs to be.

Wrapping Up

Understanding the difference between the stage and grade of cancer is key to understanding the disease’s nature and progression. They are not interchangeable terms but are complementary pieces of information that, when combined, provide a comprehensive picture of the patient’s cancer.

This picture then guides the oncologist in designing an effective treatment plan, thus highlighting the importance of accurate grading and staging in cancer care.
