Abstract


Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics,treatment protocols, and survival outcomes in Chinese CEC patients.

Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare thecontinuous variables and survival.

Results: Among the 500 CEC patients, 278 (55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171 (34.2%) patients who received surgery, 22 (12.9%) had undergonelaryngectomy. In 322 (64.4%) patients who received non-surgical treatments, 245 (76.1%) received radiotherapy. Stratified survivalanalysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomesbetween laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar inCEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy (P = 0.244).

Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with orwithout total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.
