Colorectal Cancer Staging

According to the American Cancer Society, colorectal cancer stages and corresponding 5-year survival rate as follows:

Colorectal Cancer Stage I: 85%--95%;

Colorectal Cancer Stage II: 60%--80%;

Colorectal Cancer Stage III: 30%--60%;

Colorectal Cancer Stage IV: below 5%.

Early treatment is the important factors to improve the 5-year relative survival rate of colorectal cancer. Doctors use staging information to help plan treatment and to predict a patient’s prognosis.

TNM system

The staging system most often used for colorectal cancer is TNM.

The T refers to the size and extent of the main tumor. The main tumor is usually called the primary tumor.

T1, T2, T3, T4: Refers to the size and/or extent of the main tumor. The higher the number after the T, the larger the tumor or the more it has grown into nearby tissues.

The N refers to the number of nearby lymph nodes that have cancer.

N1, N2, N3: Refers to the number and location of lymph nodes that contain cancer. The higher the number after the N, the more lymph nodes that contain cancer.

The M refers to whether the cancer has metastasized. This means that the cancer has spread from the primary tumor to other parts of the body.

M0, M1: Cancer has not spread to other parts of the body.
