Abstract
Squamous cell carcinoma of the middle thoracic esophagus (SCC-ME) often metastasizes to the neck, mediastinum, and abdomen. This study aims to assess the prognostic impact of supraclavicular (SC) and celiac (CE) lymph node (LN) metastases in patients with SCC-ME. We examined 210 patients who underwent curative esophagectomy with three-field LN dissection for SCC-ME. The clinicopathological features and survival outcomes of patients with and without SC and/or CE metastases were compared to assess the prognostic significance of SC and/or CE metastases. We observed metastases to SC and CE in 25 (11.9%) and 20 (9.5%) patients, respectively. Seven patients (3.3%) had both SC and CE metastases. Although the survival of patients with SC and/or CE metastases was worse compared with those without, that of patients with SC metastases but without CE metastases was comparable with that of patients with CE metastases but without SC metastases; the 5year overall survival rates were 35.6% and 46.2%, respectively. However, survival of patients with both SC and CE metastases was the worst among all groups, and all patients with both SC and CE metastases experienced disease recurrence. The prognosis of patients with both SC and CE metastases was extremely poor. In contrast, patients with metastasis to either one of these sites could be candidates for surgery as the main modality in a multidisciplinary strategy.
