Happy to be of assistance! Here are a few more general observations based on your last post. Going mostly from memory (I’ll go confirm later and amend if necessary). Pulmonary nodules *can* be lymph nodes, but they can be many other things also. Size, growth rate (usually expressed as “doubling time”), radiological appearance, and clinical context (e.g., primary somewhere else, CEA) are all relevant to diagnostic evaluation. PET uptake is, as you know, another factor. Most generally (there are loads of distinctions “under” this), most *nodes* are “solid.” Many primary lung malignancies are classed as “subsolid,” at least in some respect. CRC mets are usually solid. Another complication in your case is the small size of your nodules: these are just barely beyond being “micronodules” (<3mm). That makes them harder to characterize and very hard to find. It’s a positive factor diagnostically, however. Also, if I recall right, your PET uptake was on the line.
They’ve called these “indeterminate,” which seems to make sense (tiny, stable or slow growing (but with a background of treatment including 5-FU), some uptake but not lots, no other obvious explanation, e.g., infection, smoking, etc.). I would be interested in their view of (1) no (or minimal) growth over such long periods (except maybe for 1/3); (2) any clues from appearance on scans (even at this size there usually are such); (3) are they suggesting chemo to test the nodules through shrinkage/stability, or because of worries about disseminated disease, or both? (4) is there clear lymphatic involvement, no evidence of same, or unknown? and (5) is there urgency to treat now, or can they wait to watch growth? (This last assumes you aren’t considering FOLFIRI. If you are I understand why they’d want to do that right away.) Another interesting question might be whether they consider this to be oligometastatic disease, or evidence thereof, or something else? That would give you more insight into their perspective/rationale than your health, but it might be worth exploring given the complexities of your situation.
