UCell scoring, sample\u2010level summaries, pseudobulk differential analysis, Monocle2 trajectory inference, and targeted macrophage\u2013T cell interaction analysis were applied. A posttreatment SPP1 inflammatory TAM\u2010derived NR\u2010TAM signature was projected to pretreatment bulk RNA\u2010seq from the same cohort.

The NR\u2010TAM signature was partially recapitulated in pretreatment bulk RNA\u2010seq, with higher scores in NMPR but substantial group overlap. Exploratory ROC analysis showed modest discrimination for NR\u2010TAM score (AUC\u2009=\u20090.60), INHBA (AUC\u2009=\u20090.64), and the combined model (AUC\u2009=\u20090.64; LOOCV AUC\u2009=\u20090.37). INHBA was higher in NMPR cases, correlated with residual tumor burden and selected TAM\u2010related genes, showed less favorable survival trends particularly in LUSC, and its knockdown reduced proliferation and migration in lung cancer cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>An SPP1 inflammatory TAM program is associated with unfavorable pathologic response in NSCLC neoadjuvant immunotherapy.
