Pleural invasion is the presence of tumour in the pleura. Pleural invasion is poor prognosticator in lung cancer,[1][2] and important in determining the Tumour stage.
The visceral pleura is the pleura that covers the lung; tumour invasion into it is known as visceral pleural invasion (abbreviated VPI). The parietal pleural covers the chest wall.
Modified Hammar classification
Can be subgrouped:[1]
| Category | Description | Tumour stage (TNM staging) |
|---|---|---|
| PL0 | tumour confined to lung, not through elastic layer | T(any) |
| PL1 | tumour beyond elastic layer of the visercal pleura, not at pleural surface | at least T2 |
| PL2 | tumour at surface of pleura, not in parietal pleura | at least T2 |
| PL3 | tumour within parietal pleura and visceral pleura | at least T3 |
