Question:
Behavior--Lung: How is behavior to be coded for a diagnosis of adenocarcinoma of a lung tumor that is further classified per the CAP protocol as, "non-mucinous bronchiolo-alveolar carcinoma (adenocarcinoma in situ)" while the pathologist also classifies the tumor as pT1b, pN0? See Discussion.
Discussion:
Is the following case coded with an invasive or in situ behavior when a RUL lobectomy specimen reveals adenocarcinoma and the Histologic Type per the CAP protocol layout is non-mucinous bronchiolo-alveolar carcinoma (adenocarcinoma in situ)? The stage per the pathologist is pT1b, pN0. Per the COMMENT section in the pathology report, "The terminology adenocarcinoma in situ is based on a recent publication in the Journal of Thoracic Oncology (Volume 6, #2, February 2011). Based on this criterion, the behavior represents adenocarcinoma in situ with no evident invasive component."
Answer:
Code the behavior as in situ. The pathologist has the final say on the behavior of the tumor. This pathologist is indicating that in his opinion based on a recent publication, this tumor is in situ.
