Question:

EOD-Extension--Lung: Are "aortico-pulmonary window", "paratracheal space", and "subcarina" coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.

Discussion:

Would a lung tumor that extends into the AP window be synonymous with extension into the mediastinum? If so, would this also apply to extension to subcarina, paratracheal space, and other such terms corresponding to areas listed in the mediastinal lymph node field under code 2?

Answer:

For cases diagnosed between 1998-2003:

Extension into the aortico-pulmonary window, would be coded in the EOD-Extension field as 70 [mediastinal extension]. If the tumor extends into the paratracheal space, subcarina, or other areas listed under the code 2 in lymph nodes, code the EOD-Extension field to 70 to capture this type of involvement.
