Mesothelioma Staging.

Staging of mesothelioma cancer will determine the treatment that can be offered. Currently there are three staging methods in use for pleural mesothelioma. The three staging systems are the Butchart system, TNM system, and the Brigham system. The Butchart system is the oldest and the Brigham system the latest. There is not staging for peritoneal mesothelioma.

Butchart System for Mesothelioma staging.
Stage 1: Mesothelioma is confined to the pleura of either the left or right lung and possibly the diaphragm of the same side.
Stage II: Mesothelioma has spread to the chest wall or the esophagus, heart, lymph nodes and pleura of both sides.
Stage III: Mesothelioma has extended beyond the diaphragm into the abdominal cavity and peritoneum. Lymph glands outside the chest may be involved.
Stage IV: Metastasis or spread of the tumor through the blood stream to other organs of the body.

 TNM (Tumor, lymph Nodes, Metastases.)
Stage I : Mesothelioma cancer of either right or left pleura. Spread to lung, pericardium or diaphragm. Lymph nodes not involved.
Stage II : As above but spread to lymph glands on the same side of the pleura.
Stage III : Spread to chest wall, ribs, heart, esophagus and muscles.
Stage IV : Spread to lymph nodes on the other side of the tumor. Spread to pleura or lung on the other side or into the organs in the abdomen or into the neck. Metastases through the blood stream to other organs.

Brigham System of Mesothelioma staging.
Stage I : Mesothelioma cancer is resectable. Lymph nodes not involved.
Stage II : Tumor resectable. Lymph nodes involved.
Stage III : Tumor nor resectable. Spread into chest wall, heart or through the diaphragm and peritoneum.
Stage IV : Spread of mesothelioma cancer through the blood stream to distal organs of the body.
