Butchart System


Mesothelioma staging is an important part of diagnosis. There are several systems for staging pleural mesothelioma. The oldest system is the Butchart System. The stages are based on tumor size and how far the cancer has spread. Stage 1 and Stage 2 mesothelioma, under the Butchart system, may respond well to treatment. Stages 3 and 4 often mean that palliative care is the only treatment option.

Stage 1 Mesothelioma

Under the Butchart system, in Stage 1 mesothelioma the cancer is only present on one side of the chest cavity, not both. Mesothelioma is seen in the right or left pleural membrane and possibly the diaphragm on the same side.

Diagnosis of Stage 1 mesothelioma is rare, but when mesothelioma is diagnosed in this stage it may be possible to remove all of the cancer with surgery and make a full recovery.

Stage 2 Mesothelioma

In Stage 2 pleural mesothelioma, the cancer has invaded both sides of the pleura. The cancer may also have moved into the chest wall, heart, stomach, or esophagus. Lymph nodes in the chest may be affected.

Stage 2 mesothelioma may still respond to surgery and other treatments such as chemotherapy, radiation, gene therapy, and immunotherapy. Stage 2 mesothelioma diagnosis is uncommon.

Stage 3 Mesothelioma

Stage 3 pleural mesothelioma is advanced mesothelioma. The cancer has spread through the diaphragm into the peritoneum (lining of the abdomen), and may also involve lymph nodes beyond the chest.

Curative treatments are not generally considered an option for Stage 3 mesothelioma, but there are exceptions and the appropriate course of treatment will depend on a number of factors, not just Butchart Staging. Surgery and other treatments may result in a longer survival for Stage 3 mesothelioma patients. Palliative care is definitely needed in Stage 3 mesothelioma.

Stage 4 Mesothelioma

Stage 4 mesothelioma is the final stage of mesothelioma. The cancer has spread (metastasized) through the bloodstream to distant organs and tissues and may be found as far away as the brain. At this stage, palliative care is very important. Pain management becomes a major part of care. Curative treatments are no longer an option.
