Is this description the same thing as invasive mucinous adenocarcinoma or some variation type?
You'd have to defer to the pathologist writing the report, but it is probably the same. As Dr. West has written:
"There is actually a continuum from pure BAC to BAC with focal invasion, to adenocarcinoma with BAC features, and then invasive adenocarcinoma with no BAC component:
Although pathologists have sometimes been rigid in their use of the term “BAC” to describe the pure form, many clinicians have observed that the distinctive features of BAC in terms of natural history and behavior can be seen not only with pure BAC but in the more common situation of a combination of BAC with some component of invasive adenocarcinoma. Accordingly, clinicians have generally considered the eligibility for a clinical trial on BAC to depend on having an adenocarcinoma with at least BAC features, rather than restrict to a much msaller population of patients with pure BAC." - http://cancergrace.org/lung/2010/07/09/basics-of-bac/
Since the pathologist used the term "adenocarcinoma", he/she was most likely referring to "adenocarcinoma with BAC features".
<p>I began visiting GRACE in July, 2008 when my wife Liz was diagnosed with lung cancer, and became a forum moderator in January, 2010. My beloved wife of 30 years passed away Nov. 4, 2011 after battling stage IV lung cancer for 3 years and 4 months</p>
Thank you up very much...makes sense....
