Herein, the authors analyzed the National Cancer Data Base to evaluate overall survival (OS) between patients treated with surgical and organ\u2010preserving modalities.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The National Cancer Data Base was queried for patients diagnosed from 2004 through 2012 with T4M0 laryngeal cancer who underwent either laryngectomy (surgery) with adjuvant RT (SRT), chemotherapy starting concurrently within 7 days of RT (CCRT), or multiagent induction chemotherapy starting 43 to 98 days before RT (ICRT). Multivariate analysis and propensity score matching were used to explore the association between the intervention and OS. Recursive partitioning analysis was performed to identify groups benefiting from particular modalities.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A total of 1559 patients who underwent SRT, 1597 patients who underwent CCRT, and 386 patients who underwent ICRT were included. Adjusting for covariates, CCRT was found to be associated with inferior OS compared with SRT (hazard ratio [HR], 1.55; 95% confidence interval [95% CI], 1.41\u20101.70 [<jats:italic>P<\/jats:italic>&lt;.01]) and with ICRT (HR, 1.25; 95% CI, 1.07\u20101.45 [<jats:italic>P<\/jats:italic>&lt;.01]). OS among the patients treated with SRT did not appear to differ significantly from that of the ICRT cohort (HR, 0.87; 95% CI, 0.73\u20101.03 [<jats:italic>P\u2009=\u2009<\/jats:italic> 0.10]), a finding confirmed with propensity score matching. Recursive partitioning analysis identified no subset of patients that derived an OS benefit from either approach over the other.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>OS among patients undergoing SRT was found to be superior to that of patients treated with CCRT but did not significantly differ from that of those undergoing ICRT. Because these intriguing findings require validation, SRT should remain the standard of care for patients with this disease. However, organ preservation with ICRT may be a reasonable alternative in certain patients. <jats:bold><jats:italic>Cancer<\/jats:italic> 2017;123:600\u2013608.<\/jats:bold> \u00a9 <jats:italic>2016 American Cancer Society<\/jats:italic>.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cncr.30382","type":"journal-article","created":{"date-parts":[[2016,10,13]],"date-time":"2016-10-13T12:18:48Z","timestamp":1476361128000},"page":"600-608","source":"Crossref","is-referenced-by-count":56,"title":["A comparison of overall survival for patients with T4 larynx cancer treated with surgical versus organ\u2010preservation approaches: A National Cancer Data Base analysis"],"prefix":"10.1002","volume":"123","author":[{"given":"William A.","family":"Stokes","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernard L.","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shilpa","family":"Bhatia","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayman J.","family":"Oweida","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel W.","family":"Bowles","sequence":"additional","affiliation":[{"name":"Division of Medical Oncology, Department of Medicine University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Raben","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie A.","family":"Goddard","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica D.","family":"McDermott","sequence":"additional","affiliation":[{"name":"Division of Medical Oncology, Department of Medicine University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sana D.","family":"Karam","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Colorado School of Medicine Aurora Colorado"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,10,11]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21332"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199106133242402"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.27.3276"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-5998(99)70052-5"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2015.0102"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.124.9.964"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlg.0000236095.97947.26"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.133.12.1270"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2015.03.004"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(13)70011-1"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2013.54.6309"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(92)90133-8"},{"key":"e_1_2_8_14_1","unstructured":"Coca\u2010PerraillonM.
