TNM staging system - Wikipedia
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the extent of spread of cancer.It is a classification system of the anatomical extent of tumor cancers. It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia and tumors of the central nervous system.
Tumor Grading
To grade a tumor a biopsy is done. The doctor removes part of the tumor or all of it and sends it to a pathologist, who takes samples of the tumor and assesses the cells of the tumor under a microscope.
Tumor Staging
Staging tells about the main tumor (location, size etc.), and if the cancer has spread to other parts of the body like the lymph nodes or other organs.
Why is cancer staging needed?
For most types of cancer, doctors need to know how much cancer there is and where it is (among other things) to help determine the best treatment options. For example, the best treatment for an early-stage cancer may be surgery or radiation, while a more advanced-stage cancer may need treatments that reach all parts of the body, such as chemotherapy, targeted drug therapy, or immunotherapy .
Why do we do clinical staging after cancer surgery?
Staging might be done after this first treatment to help measure the cancer’s response to treatment. This can be done the same way as clinical staging (if surgery hasn’t been done yet), which can help determine what type of surgery should be done. Or it can be done after surgery (the same way as pathological staging), which might give more precise information.
How is the overall stage determined in TNM?
In the TNM system, the overall stage is determined after the cancer is assigned a letter or number to describe the tumor (T), node (N), and metastasis (M) categories.
What is cancer stage?
The cancer stage is also a way for doctors to describe the extent of the cancer when they talk with each other about a person’s cancer. Not all cancers are staged. For example, leukemias are cancers of the blood cells and therefore typically have spread throughout the body by the time they are found.
Why is grade important in cancer?
This is also called differentiation. Grade can be important because cancers with more abnormal-looking cells tend to grow and spread faster.
Why is cancer stage important?
A cancer’s stage can also be used to help predict the course it will likely take, as well as how likely it is that treatment will be successful. Although each person’s situation is different, cancers of the same type and stage tend to have similar outlooks. The cancer stage is also a way for doctors to describe the extent ...
How long do people live with cancer?
This is the percentage of people with a certain type and stage of cancer who are still alive a certain amount of time (usually 5 years) after being diagnosed. For example, if the 5-year survival rate for a certain stage of a type of cancer is 80%, it means that 80 out of 100 people who have that type and stage of cancer will still be expected to be alive after 5 years.

Why are tumors graded?
It can generally be said that the less differentiated tumor cells are, the faster they grow and the earlier they penetrate surrounding tissue. Tumors are graded using the abbreviations G1 to G4: the higher the grade, the less differentiated and the more malignant the tumor is.
What does the letter T mean in cancer?
So this is what the three letters stand for: T refers to the primary tumor (original tumor).
What is a TNM?
The abbreviation “TNM” stands for tumor (T), nodes (N), and metastases (M). “Nodes” indicates whether or not the tumor has spread into neighboring (regional) lymph nodes. These are lymph nodes that are located in the drainage area of the affected organ. “Metastases” tells us whether or not the tumor has spread to other parts of the body, forming what is known as distant metastases. So this is what the three letters stand for: 1 T refers to the primary tumor (original tumor). 2 N describes whether or not regional lymph nodes are affected. 3 M describes whether or not distant metastases have been found.
What is TNM classification?
Doctors and researchers all use what is known as TNM classification. There is an international system for the classification of cancerous tumors. This helps to describe cancers and compare the results of medical tests and examinations. Doctors and researchers all use what is known as TNM classification.
What does the number after the letters mean?
The numbers after the letters indicate how big the tumor is and how far it has spread. The combination of letters and numbers describes the type of cancer, its size, characteristics and extent. Doctors often use this classification as a basis for making a prognosis and proposing an individual treatment plan.
What is the most commonly used staging system?
Staging can be of relevance for the prognosis of the disease. The most commonly used staging system is that of the International Union against Cancer (UICC).
What does p mean in cancer?
p(for “pathological ”) means that removed tissue was tested in a laboratory, and that the diagnosiswas made based on the results of that test. r(for “recurrence”) means that a tumor has returned. Rmeans that remaining cancer tissue was found after treatment.

How to determine the stage of cancer?
determine the stage of cancer. detect cancer that remains after treatment ( residual disease) or that has returned after treatment. assess how well a treatment is working. monitor whether the treatment has stopped working. Although an elevated level of a circulating tumor marker may suggest the presence of cancer and can sometimes help ...
What are the two types of tumor markers?
There are two main types of tumor markers: circulating tumor markers and tumor tissue markers.
Why are tumor markers important?
Because tumor markers can be used to predict the response of a tumor to treatment and for prognosis, researchers have hoped that they might also be useful in screening tests that aim to detect cancer early, before there are any symptoms.
What does it mean when a tumor marker decreases?
For example, a decrease in the level of a circulating tumor marker may indicate that the cancer is responding to treatment, whereas an increasing or unchanged level may indicate that the cancer is not responding.
What happens when a test has low specificity?
When a test has low specificity, people have to have further testing to determine whether cancer is present. And some screening tests based on tumor markers have been shown to lead to overdiagnosis, which happens when people are diagnosed with cancers that would never have affected them during their lifetimes.
Where are tumor tissue markers found?
Tumor tissue (or cell) markers are found in the actual tumors themselves, typically in a sample of the tumor that is removed during a biopsy. Tumor tissue markers are used to:
What is Tumor Staging?

How to determine the stage of a tumor?
To determine the stage of a tumor, a healthcare provider may order lab tests, X-rays, or other procedures depending on each individual case. Cancer staging can be categorized into clinical stage and pathologic stages. The clinical staging is performed before the tumor is removed.
What is the TNM staging system?
Many staging systems, such as the TNM staging system, are used to classify various types of cancers. Certain other staging systems are designed to stage a specific type of cancer. The information used in most staging systems include: The type of cell in the tumor (i.e., adenocarcinoma, squamous cell carcinoma, etc.)
What is staging in cancer?
The staging of a tumor is undertaken based on several characteristics of the tumor, such as its size, spread and cellular abnormalities, within the tumor.

The most common system for staging cancer in the form of solid tumor is the TNM system. Most providers and cancer centers use it to stage most cancers. The TNM system is based on: Numbers are added to each category that explains the size of the tumor and how much it has spread.
What is cancer staging?
Cancer staging is a way to describe how much cancer is in your body and where it is located in your body. Staging helps determine where the original tumor is, how big it is, whether it has spread, and where it has spread. Cancer staging can help your health care provider:
How does cancer spread?
As the cancer progresses, cancer cells from the tumor can break away and spread to other parts of the body through the bloodstream or lymph system. When cancer spreads, tumors can form in other organs and parts of the body. The spread of cancer is called metastasis. Cancer staging is used to help describe the progression of cancer.
What does M0 mean in cancer?
M0: No metastasis found (cancer has not spread) M1: Metastasis is found (cancer has spread to other parts of the body) As an example, a bladder cancer T3 N0 M0 means there is a large tumor (T3) that has not spread to lymph nodes (N0) or anywhere else in the body (M0).
Why are not all cancers staged in the TNM system?
This is because some cancers, particularly blood and bone marrow cancer such as leukemia, do not form tumors or spread in the same way. So other systems are used to stage these cancers.
What is the term for the spread of cancer?
The spread of cancer is called metastasis. Cancer staging is used to help describe the progression of cancer. It is often defined by: Location of the primary (original) tumor and type of cancer cells. Size of the primary tumor. Whether the cancer has spread to lymph nodes. Number of tumors from the cancer that has spread.

Also called carcinoma in situ, or CIS. CIS is not cancer, but it may become cancer. Stage I, Stage II, and Stage III. Cancer is present. The higher the number, the larger the cancer tumor and the more it has spread into nearby tissues. Stage IV. The cancer has spread to distant parts of the body.
What is stage IV cancer?
Stage IV. The cancer has spread to distant parts of the body. Another staging system that is used for all types of cancer groups the cancer into one of five main categories. This staging system is more often used by cancer registries than by doctors.
How many stages of cancer are there in TNM?
The TNM system helps describe cancer in great detail. But, for many cancers, the TNM combinations are grouped into five less -detailed stages. When talking about your cancer, your doctor or nurse may describe it as one of these stages:
