Risk factors and survival analysis for synchronous esophageal carcinoma in patients with hypopharyngeal carcinoma / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To investigate the risk factors and survival status of hypopharyngeal carcinoma with synchronous second primary carcinoma of the esophagus.@*Methods@#One hundred and sixty patients with newly diagnosed hypopharyngeal carcinoma from January 2009 to December 2012 were retrospectively reviewed. The clinical data, tumor-related information and follow-up results were collected and analyzed.@*Results@#Forty-three synchronous esophageal carcinomas (27%) were detected in 160 patients with hypopharyngeal carcinoma, and most patients (72%) were at an early stage. On univariate analysis, the median age of less than 55 years old (χ2=4.525, P=0.033), excessive alcohol consumption (χ2=6.942, P=0.008) and invasion site more than 3 anatomical regions (χ2=21.503, P=0.000) had a significant correlation with the occurrence of synchronous esophageal carcinomas. Multivariate analysis showed that excessive alcohol consumption (OR=4.787, P=0.029) and invasion site more than 3 anatomical regions (OR=14.391, P=0.000) were independent risk factors. The median survival time was 26 months in 43 patients with synchronous esophageal carcinomas, which was significantly lower than that (58 months) in patients without secondary primary esophageal carcinomas (χ2=11.981, P=0.001).@*Conclusions@#There is a high incidence of synchronous esophageal carcinoma in hypopharyngeal carcinoma patients, affecting the prognosis of hypopharyngeal carcinoma. Surveillance for esophageal carcinomas in patients with hypopharyngeal carcinoma, especially in excessive alcohol drinkers, is warranted.
