Abstract
OBJECTIVE: Patients with advanced hypopharyngeal squamous cell carcinomas (HSCCs) have poor prognoses. The use of surgical or non-surgical treatments for these patients remains a topic of debate. This study compared survival following surgical and non-surgical treatments of patients with advanced HSCC based on the Surveillance, Epidemiology and End Results (SEER) database. METHODS: Patients diagnosed with hypopharyngeal cancer from 2004 to 2018 were identified from the SEER database. Patients were divided into non-surgical group and surgical group, and patients in the surgical group were further divided into three groups: surgery-only, surgery with adjuvant radiation therapy and surgery with adjuvant chemoradiation therapy. The primary endpoint was overall survival (OS), and the secondary outcome was cancer-specific survival (CSS). Outcomes were analyzed using Kaplan-Meier analysis. A multivariate Cox regression analysis was also used to identify independent prognostic factors. RESULTS: The records of 1568 eligible patients with stage III or IV HSCC were examined. Receipt of surgery was associated with a longer OS [hazard ratio (HR) = 0.47, 95% confidence interval (CI): 0.4-0.56] and a longer CSS (HR = 0.47, 95% CI: 0.38-0.57) after adjusting for age, sex, race, tumor site, tumor size, tumor grade, TNM stage, AJCC stage, number of carcinomas, prior cancer, receipt of radiotherapy, and receipt of chemotherapy. The results for OS were similar in an exploratory analysis of different patient subgroups. CONCLUSION: Among patients with advanced HSCC in the SEER database, treatment with surgery was associated with longer OS and CSS than treatment with a non-surgical modality.
