Colorectal Cancer Staging and Prognosis

Colorectal Cancer Staging and Prognosis

The Colorectal cancer staging can be made according to the TNM staging system from the WHO organization, the UICC and the AJCC. The Astler-Coller classification (1954) or the Dukes classification (1932) are now less used.

Colorectal Cancer Stages

Medical practitioner, doctor and surgeon will take note to the stage of cancer because it is the most important factors for them to determine the prognosis and then treatment options. To find out the colorectal cancer stages, it will involve a physical exam, biopsy test and any imaging test necessary. If the colorectal cancer stages can be determine by the results from the mentioned procedure just now, it is called a clinical stage.

Maybe for some cases, the patient has to get a surgery to see how far the cancer developed and then the result from the surgery can be combined with the clinical stage, it is called pathologic stages. The surgery result also can be combined with some factors to be used in the clinical stage.

Pathologic stage is considered to be more accurate than clinical stage because it can describe how far the cancer developed or extent in the body. It is also to allow the doctors to give you the option of treatment based on your condition.

  1. Colorectal Cancer Stage 1

    Colorectal Cancer which has invaded the mucosa and the submucosa is considered stage 1 Colorectal cancer. The submucosa is the underlining of the large intestine and it lies beneath the mucosa. In stage 1 Colorectal cancer, malignant cells may have also affected the deeper muscle layer of the colon wall, but have not invaded any areas outside of the colon.

  2. Colorectal Cancer Stage 2

    When cancer has spread past the colon wall, but has not affected the lymph nodes, it is considered stage II colon cancer. This condition is subdivided into three stages:
    Colorectal Cancer Stage 2A has spread to the serosa or outer colon wall, but not beyond outer barrier.
    Colorectal Cancer 2B has spread past the serosa but has not affected nearby organs.
    Colorectal Cancer 2C has affected the serosa and the nearby organs.

  3. Colorectal Cancer Stage 3

    Colorectal Cancer Stage 3 has spread past the lining of the colon and has affected the lymph nodes is considered stage III colon cancer. In this stage, even though the lymph nodes are affected, the cancer has not yet affected other organs in the body. This stage is further divided into three categories: 3A, 3B and 3C. Where your cancer is staged in these categories depends on a complex combination of which layers of the colorectal wall are affected and how many lymph nodes have been attacked.

According to the National Cancer Institute in the US, patient with stage 1 colorectal cancer having about 93% of survival rate while stage II is between 72% and 85%, and stage III is still high as 83%. What we have to worry here is the prognosis of stage IV, which is only 8% of the patient can live for five years after diagnosed.

  2. Lymphatic System Damages

    Our body using lymph nodes and lymph vessels to control the immune system in order to fight against diseases. It is the lymphatic’s system job to protect our body from any bacterial infection or foreign substance. If the lymph glands are affected by cancer, our body will lose this preventive system and your cancer will be likely to re-occur one day.
