Question:

Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of a 2018 lung cancer case with invasive non-mucinous adenocarcinoma? For non-mucinous carcinoma/adenocarcinoma, the Solid Tumor Rules have codes for microinvasive, minimally invasive, preinvasive, and in situ. Do we default to the microinvasive/minimally invasive code?

Discussion:

Answer:

Code histology to adenocarcinoma, NOS (8140/3). The World Health Organization and the College of American Pathologists no longer recognize non-mucinous carcinoma/adenocarcinoma, NOS. Pathologists are discouraged from using this term. Microinvasive/minimally invasive lung tumors have very specific criteria and these criteria do not apply to non-mucinous carcinoma, NOS.
