Although active surveillance reduces the upfront costs of surgery and hospital stay, it requires repeated diagnostic tests and, for some patients, delayed surgery and hospitalization during follow-up.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To assess the cost-effectiveness of active surveillance compared with standard surgery after nCRT.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n This prespecified cost-effectiveness analysis from a health care perspective conducted at 12 hospitals in the Netherlands as a secondary analysis of the Surgery as Needed for Oesophageal Cancer (SANO) trial, a noninferiority, cluster randomized study, enrolled patients with esophageal cancer who achieved a CCR after nCRT between November 8, 2017, and January 17, 2021, with follow-up for up to 5 years. Data were analyzed on June 1, 2025.<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n Active surveillance, consisting of repeated response evaluations at 6, 9, 12, 16, 20, 24, 30, 36, 48, and 60 months after nCRT, compared with standard surgery.<\/jats:p>\n <\/jats:sec>\n \n Main Outcome and Measures<\/jats:title>\n Incremental cost-effectiveness of active surveillance vs standard surgery and quality-adjusted life-years (QALYs) with 95% CIs up to 5 years were derived with bootstrapping, with 80% of patients (247 of 309) having complete follow-up. Incremental net monetary benefit (iNMB) was calculated at varying willingness-to-pay thresholds. All analyses followed the modified intention-to-treat principle. Costs are given in Euros (currency exchange rate of \u20ac1\u2009=\u2009US $1.16 as of June 11, 2026).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Among 309 patients (198 in the active surveillance group; median age, 69 years [IQR, 63-74 years]; 156 men [79%]; and 111 in the standard surgery group; median age, 68 years [IQR, 61-73 years]; 86 men [77%]), those in the active surveillance group had a mean of 2.99 QALYs (95% CI, 2.73-3.26) at 5 years vs 2.88 QALYs (95% CI 2.69-3.06) in the standard surgery group. Mean health care costs per patient at 5 years were \u20ac36\u202f733 (95% CI, \u20ac33\u202f530-\u20ac40\u202f009) in the active surveillance group vs \u20ac45\u202f106 (95% CI, \u20ac39\u202f449-\u20ac51\u202f545) in the standard surgery group. The incremental QALY for active surveillance was 0.11 (95% CI, \u22120.10 to 0.33) and mean costs were \u20ac8374 lower (95% CI, \u20ac1792-\u20ac15\u202f355) compared with standard surgery. At a willingness-to-pay threshold of \u20ac80\u202f000 per QALY, the mean iNMB was \u20ac17\u202f568 (95% CI, \u2212\u20ac725 to \u20ac37\u202f497), indicating that active surveillance is cost-effective. Bootstrap analysis showed that 97% of replications fell in the cost-effective region.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this secondary analysis of a randomized clinical trial of patients with esophageal cancer achieving a CCR after nCRT, active surveillance was cost-effective over a 5-year horizon compared with standard surgery. Broader implementation of this strategy among appropriately selected patients would most likely reduce health care costs without compromising health outcomes.<\/jats:p>\n <\/jats:sec>\n \n Trial Registration<\/jats:title>\n \n The Dutch Trial Register:\n NTR 6803<\/jats:ext-link>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2026.24615","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T15:30:35Z","timestamp":1785166235000},"page":"e2624615","source":"Crossref","is-referenced-by-count":1,"title":["Surveillance vs Standard Surgery and Cost-Effectiveness After Neoadjuvant Chemoradiotherapy for Esophageal Cancer"],"prefix":"10.1001","volume":"9","author":[{"given":"Sanjiv S.
