The International Association for the Study of Lung cancer (IASLC) 7th edition for lung cancer staging is as follows. This has now been updated and superseded by the 8th edition in 2016.
T staging descriptor
The parameters assessed on the T stage include size, endobronchial location, local inv...
A number of staging systems have been described for staging of malignant pleural mesothelioma. Below is the International Mesothelioma Interest Group TNM staging system.
T - Tumour
Tx: primary tumour cannot be assessed
T0: no evidence of primary tumour
The Masaoka staging system is commonly adopted for thymomas 1-3, and is the most important determinant of survival following surgical resection 4:
stage I: intact thymic capsule
stage II: capsular invasion into adjacent mediastinal fat or pleura
stage III: macroscopic invasion into adjacent o...
The IASLC (International Association for the Study of Lung Cancer) 8th edition lung cancer staging system was introduced in 2016 and supersedes the IASLC 7th edition.
It is as follows:
T: primary tumour
Tx: primary tumour cannot be assessed or tumour proven by presence of maligna...
Non-small cell lung cancer (NSCLC) staging can be accomplished both by the TNM system or by the AJCC staging system.
This staging has since been revised. See IASLC 8th edition staging.
For a general discussion of these tumours please refer to the article on non-small cell lung cancer (NSCLC).
Oesophageal cancer staging can depend slightly on whether the tumour is squamous cell or adenocarcinoma subtype. Due to the lack of a serosal layer, oesophageal cancer often tends to have mediastinal spread at the time of diagnosis.
Tx: primary tumour cannot be...
Siltzbach system is a chest radiographic staging method for sarcoidosis.
stage 0: normal chest radigraph: 10% at time of diagnosis
stage I: lymph node enlargement: 50% at time of diagnosis
stage II: lymph node enlargement and pulmonary opacities: 30% at time of diagnosis
stage III: pulmonary...
Previously, small cell lung cancer was not staged in the same manner as non small cell lung cancer, on account of its being almost never resectable at the time of diagnosis, except in rare cases where it appears as a solitary pulmonary nodule.

Visceral pleural invasion is a feature that can be seen in lung cancers. It is defined as tumour extension beyond the elastic layer of the visceral pleura. It is considered an aggressive sign and one of the most important adverse prognostic factors in non-small cell lung cancers 1.
