The only person that I recall that considered an actual hilar node extraction was Kathryn_in_MN ca 2011-2. Her hilar location was considered difficult then, that would require a hot shot thoracic surgeon willing and able to move organs at that location. Also mind their risk/benefit concerns on distant LN for unknown (micro)mets. So she didn't have hilar LN surgery and was able to buy time with chemo.
Perhaps today surgical techniques with or without machines can do a better job mechanically or slight differences in location(s).
Then the next question is what to do about potential metastatic seedlings, presumed likely to be more than lower down LN.
My take for hilar LN and met spread is similar to my prior comments on LN except more days of repair time on supernutrition after surgery, before a chronomodulated chemo formula with milder side effects but more cumulative cancer cell kill.Metastatic lymph node treatment optionsswinging for the fence
