Background: For cervical and higher-level esophageal tumors, the choice of cervical anastomosis or thoracic anastomosis is still controversial. The goal of this study was to explore the optimal surgical approach for cervicothoracic esophageal squamous tumors.
Methods: We retrospectively analyzed 3,802 consecutive patients with esophageal squamous cell tumors in Nanjing Drum Tower Hospital from Jan 2001 to Jan 2017. Twenty-six patients with cervical anastomosis and twenty-eight patients with thoracic anastomosis were evaluated.
Results: The cervical anastomosis group exhibited a greater number of resected lymph nodes (36.5±7.3 vs. 19.9±5.7, P<0.001). In addition, the cervical anastomosis group exhibited a higher recurrence rate (71.4% vs. 41.7%, P=0.047) and increased locoregional recurrence (P=0.040). Overall survival was not significantly different between groups (P=0.331). Moreover, multivariate Cox regression analysis revealed that postoperative locoregional recurrence is an independent risk factor for survival (P=0.031, 95% CI: 1.114-8.952).
Conclusions: Thoracic anastomosis led to satisfactory results in patients with cervicothoracic esophageal squamous tumors.
