Overview
Classification
- The staging of pancoast tumor is based on the TNM system.
- Pancoast tumors staging starts at T3 always, as there is invasion of chest wall. Invasion of vertebral body or the subclavian vessels is regarded as T4.

Tumor size ≤3cm in greatest dimension
|
| T2
|
- Tumor size >3cm to ≤5cm
- Tumor of any size that
- invades the visceral pleura
- involves main bronchus, irrespective of distance to the carina
- shows an atelectasis or obstructive pneumonitis that extends to the hilum
|
| T3
|
- Tumor size >5cm to 7cm
- Pancoast that involves thoracic nerve roots T1 and T2 only.
- Tumor of any size that
- invades the chest wall
- invades the pericardium
- invades the phrenic nerve
- involves main bronchus, irrespective of distance to the carina
- shows one or more satellite nodules in the same lung lobe
|
| T4
|
- Tumor size >7cm
- Involvement of C8 or higher nerve roots, brachial plexus, subclavian vessels or spine
- Tumor of any size that
- invades mediastinal fat or mediastinal structures
- invades the diaphragm
- involves the carina
- shows one or more satellite nodules in another lobe on the ipsilateral side

No regional lymph node metastasis
|
| N1
|
Nodes are ipsilateral nodes within the lung up to hilar nodes.
|
| N2
|
Nodes represent ipsilateral mediastinal or subcarinal lymphadenopathy.
|
| N3
|
Nodes represent contralateral mediastinal or contralateral hilar lymphadenopathy or any scalene or supraclavicular nodes.
