Lymph node metastasis in thoracic esophageal carcinoma.
Seventy-nine patients with thoracic esophageal carcinoma underwent transthoracic esophagectomy with neck, mediastinal, and abdominal lymphadenectomy. The operative mortality rate was 3.8%. Fifty-seven patients (72.2%) had metastasis in the lymph nodes. Though three patients with carcinoma classified as pTis had no positive nodes, nine (50.0%) of the patients with a pT1 carcinoma had positive nodes. The 5-year survival rate for 57 patients with positive nodes was 33.6%. Twenty-nine patients (36.7%) had positive nodes in the neck; 47 (59.5% ), in the mediastinum; and 33 (41.8%), in the abdomen. Their 5-year survival rates were 30.0%, 24.4%, and 38.4%, respectively. The differences between these rates were not statistically significant. These results indicate that the neck lymph nodes should be regarded as part of the regional lymph nodes and that esophagectomy with wide lymph node dissection improves the long-term survival of patients with thoracic esophageal carcinoma.
