Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/22/2009 [ Schema ]

Pleura

CS Extension

Note 1: This AJCC staging system applies only to pleural mesotheliomas. Peritoneal and pericardial mesotheliomas are not TNM staged.
Note 2: Pleural effusion does not affect the coding of the CS Extension field, but is coded as Site-Specific Factor 1.
Note 3: Code 100 for Invasive tumor (mesothelioma) confined to pleura [NOS], has been made obsolete. All previously coded cases with code 100 need to be converted to code 160.

* The mapping to Summary Stage 1977 and Summary Stage 2000 depends on the value of Site-Specific Factor 1, Pleural Effusion. See the extra table, Extension Pleural Effusion Table, for details.
