Abstract

Radiotherapy (RT) and/or concurrent chemoradiation (CRT) is the mainstay for the treatment of locally advanced head-and-neck cancer (LAHNC). Sepsis remains a poorly understood and unrecognized event in head-and-neck cancer. The study aims to hypothesize a 'toxicity syndrome' leading to sepsis and subsequent sepsis-related deaths. A retrospective audit of all 125 LAHNC patients treated radically from January 2013 to June 2017 was conducted. A total of fifteen toxic deaths were reported. Thirteen deaths were attributed to sepsis. Individual toxicity for death was ascertained only for three cases. A toxicity syndrome namely 'mucositis-dysphagia-aspiration-sepsis (MDAS) complex' was proposed as the cause of death in the rest ten cases. The authors recommend the surveillance of the 'MDAS complex' for the prevention of early toxicity-related deaths in patients with LAHNC undergoing RT or CRT.
