Sudden death after operation, radiotherapy or chemoradiotherapy for head and neck cancer

Abstract

Abstract.Objective: The purpose of this report to determine sudden death following operation, radiotherapy (RT) or chemoradiotherapy (CRT) for head and neck cancer.Study Design: Retrospective, observational, single-center.Methods: Data from 729 consecutive patients diagnosed with head and neck cancer (confirmed using multiple modalities) who underwent operation, RT or CRT at Kagoshima University Hospital between April 2011, and March 2020 were analyzed. A total of 199 patients underwent operation, 223 patients underwent RT and 307 underwent CRT. 175 patients who received operation, 118 patients who received RT and 190 who received CRT had a complete response.Results: There were 13 cases of sudden death reported in 10 years. 12 were male and one was female. Sudden death occurred in 3/175 patients (1.7%) who received operation, in 4/118 patients (3.4%) who had received RT and in 6/190 (3.1%) who had received CRT. Conclusions: We present the first report on cases of sudden death after operation, RT and CRT for head and neck cancer. Otolaryngologists should still follow these patients carefully after such treatment given that sudden death does occur in some patients.
