Risk factors for 30-day mortality in patients with head and neck cancer bleeding in the emergency department

Abstract

Background: Acute head and neck cancer (HNC) bleeding is a life-threatening situation that frequently presents to the emergency department (ED). The purpose of the present study was to analyze the risk factors for the 30-day mortality in patients with HNC bleeding.

Methods: We included patients who presented to the ED with HNC bleeding (n = 241). Patients were divided into the survivor and nonsurvivor groups. Variables were compared, and the associated factors were examined with Cox's proportional hazard model.

Results: Of the 241 patients enrolled, the most common bleeding site was the oral cavity (n = 101, 41.9%). More than half of the patients had advanced HNC stage while 41.5% had local recurrence. The proportion of active bleeding was significantly higher in the nonsurvivor group (70.5% vs. 53.3%, p = 0.038). 42.3% received blood transfusion and 5.0% required inotropic support. In total, 21.2% of the patients experienced rebleeding, and 18.3% died within 30 days. Multivariate analyses indicated that a heart rate > 100 (beats/min) (HR = 2.42; Cl 1.15-5.06; p = 0.019) and inotropic support (HR = 3.00; Cl 1.14-7.89; p = 0.026) were statistically significant independent risk factors for 30-day mortality.

Conclusions: The results of this study may aid physicians in the evaluation of short-term survival in HNC bleeding patients and provide critical information for risk stratification and medical decisions.
