Stage Information
Patients with stage I disease have a significantly better prognosis than those
with more advanced stages. Because of the relative rarity of this
disease, exact survival information based upon stage is limited.[1] A proposed
staging system based upon thoracic surgery principles and clinical data is
shown below.[2] It is a modification of the older system proposed by Butchart
et al.[3] Other staging systems that have been employed, including the current international TNM staging system, are summarized by the International
Mesothelioma Interest Group.[4]
- Stage I: Disease confined within the capsule of the parietal pleura
(i.e., ipsilateral pleura, lung, pericardium, and diaphragm).
- Stage II: All of stage I with positive intrathoracic (N1 or N2) lymph nodes.
- Stage III: Local extension of disease into the following areas, e.g., chest wall or
mediastinum, heart or through the diaphragm or peritoneum, with or without
extrathoracic or contralateral (N3) lymph node involvement.
- Stage IV: Distant metastatic disease.
Localized malignant mesothelioma
See description of stage I above.
Advanced malignant mesothelioma
See descriptions of stages II, III, and IV above.
For the purposes of the discussion of treatment in this summary, the disease is
categorized as either localized or advanced.
