The median (range) follow-up was 14.2 (3.5-28.7) months. Compared with $26\u202f602.67 for up-front surgery, NAT was associated with mean overall costs of $51\u202f561.02, or a 93.8% increase, equivalent to $24\u202f958.36 (95% CI, $22\u202f057.95 to $24\u202f692.43) per patient, which was primarily associated with the drug acquisition costs of atezolizumab ($30\u202f603.96). NAT was associated with mean cost reductions from $12\u202f707.07 to $10\u202f543.71 (17.0%) in surgery and $11\u202f711.97 to $7157.32 (38.9%) in radiation across all patients compared with up-front surgery. Adjuvant radiation therapy was obviated in 5 of 17 patients not previously irradiated (29.4%), reducing costs of radiation. Mean (SD) surgical complexity was reduced from 63.81 (30.55) to 44.71 (32.49) work relative value units (wRVUs; difference, 19.10 wRVU; 95% CI, 5.00 to 33.20 wRVU). NAT was associated with 5 fewer free flaps, 4 fewer neck dissections, 5 more organ-preserving resections, and 3 conversions from inpatient to outpatient surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions and Relevance<\/jats:title><jats:p>This study found that treatment with 3 doses of NAT was associated with an overall cost increase compared with up-front surgery, driven by drug acquisition costs, and cost reductions from less extensive surgical resections and obviated adjuvant radiation.
