Examples of cancers with different staging systems.

Staging cancer systems. The Commission on Cancer CoC of the American College of Surgeons requires that the American Joint Committee on Cancer AJCC staging system be completed on all applicable sites and histologies. Some blood cancers or lymph system cancers have their own staging systems. There are two staging classifications developed by SEER.

The systems mean that doctors have a common language to describe the size and spread of cancers. TNM stands for Tumour Node Metastasis. Doctors have a common language to describe the size and spread of cancers.

Stage 1 describes an early cancer that has not spread anywhere else in the body. Below is an example of one common method of staging. Stage 0 indicates that the cancer is where it started in situ and hasnt spread stage I the cancer is small and hasnt spread anywhere else.

You are likely to see your cancer described by this staging system in your pathology report unless you have a cancer for which a different staging system is used. There are 2 main types of staging systems for cancer. There are 2 main types of staging systems for cancerthese are the TNM system and the number system.

Staging systems are key to predict the prognosis of patients with cancer to stratify the patients according to prognostic variables in the setting of clinical trials to allow the exchange of information among researchers and finally to guide the therapeutic approach. These are the TNM system and the number system. The COC and NPCR require summary staging on the sites or histologies not included in AJCC staging.

The systems mean that. The TNM system is the most widely used cancer staging system. Another commonly used staging system is the number system.

There are usually 3 or 4 number stages for each cancer type. The American Joint Committee on Cancer AJCC and the Union for International Cancer Control UICC maintain the TNM classification system as a way for doctors to stage many different types of cancer based on certain common standards. They classify cancers based on the extent of tumour or the location of the tumour in relation to where it arose.

The TNM Staging System. General Guidelines for Staging all Schemes. Common cancers using TNM staging The most common cancers that doctors stage using the TNM system are breast colorectal stomach oesophagus pancreas and lung Other cancers staged with the TNM system include soft tissue sarcoma and melanoma Staging systems exist for 52 sites or types of cancer 8.

Stage 4 describes a cancer that has spread to other parts of the body. There are different types of systems used to stage cancer but the most common and useful staging system for most types of cancer is the TNM system. Summary staging is the most basic staging system and it is based on the theory of cancer growth which uses all information available in the medical record clinical and pathological.

Extent of disease and summary stage. Extent of disease EOD coding is required for all SEER programs funded through the National Cancer Institute. Types of staging systems.

Most hospitals and medical centers use the TNM system as their main method for cancer reporting.
