Dukes classification

Dukes classification is a system used to categorize the stages of colorectal cancer. It was developed by Dr. Cuthbert E. Dukes in the 1930s and has been widely used in the medical field.

Overview

The Dukes classification system is divided into three stages: Dukes A, Dukes B, and Dukes C. Each stage represents the progression of the cancer, with Dukes A being the earliest stage and Dukes C being the most advanced.

Dukes A

In Dukes A, the cancer is confined to the inner lining of the colon. It has not spread beyond the mucosa, or the innermost layer of the colon.

Dukes B

In Dukes B, the cancer has spread to the muscle layer of the colon. It may have also spread to the serosa, or the outermost layer of the colon, but it has not spread to the lymph nodes.

Dukes C

In Dukes C, the cancer has spread to the lymph nodes. It may also have spread to other parts of the body, such as the liver or lungs.

Use in Medical Practice

The Dukes classification system is used by doctors to determine the best course of treatment for patients with colorectal cancer. It can also help predict a patient's prognosis.
