Mediastinoscopic esophagectomy for patients with early esophageal cancer.
Journal of Thoracic Disease 2015 July
OBJECTIVE: The purpose of this study was to detect the feasibility, safety, and effectiveness of mediastinoscopic esophagectomy for early esophageal cancer.
METHODS: The clinical data of 194 patients who underwent mediastinoscopic esophagectomy for early esophageal cancer in our center from December 2005 to October 2014 were retrospectively analyzed.
RESULTS: All the surgery was performed successfully. The average duration of thoracic surgery was 48.2±7.8 min and the average intra-operative blood loss was 128.1±34.5 mL. An average of 3.1±1.6 lymph node stations were dissected, with an average number of dissected lymph nodes being 9.38±6.2, among which 4.2±5.4 were mediastinal lymph nodes. No peri-operative mortality was noted, and the rate of peri-operative morbidity was 13.4%. The median duration of follow-up was 39 [3-108] months, and the overall survival was 72.73%. The overall survival rates significantly differed among different T stages; more specifically, the 5-year survival was 95.23% in patients with stage T1a esophageal cancer, 70.15% for T1b, and 55.56% for T2 (P<0.001). The overall survival was significantly better in patients with negative lymph nodes than those with lymph nodes metastasis (P=0.003); more specifically, the 5-year survival rate was 84.9% for N0, 62.5% for N1, and 50.0% for N2 + N3.
CONCLUSIONS: The mediastinoscopic esophagectomy can achieve a similar effectiveness as the conventional thoracoscopic surgery for patients with early stage esophageal cancer.
