Thoracic recurrent laryngeal lymph node metastases predict cervical node metastases and benefit from three-field dissection in selected patients with thoracic esophageal squamous cell carcinoma



Thoracic recurrent laryngeal lymph node metastases predict cervical node metastases and benefit from three-field dissection in selected patients with thoracic esophageal squamous cell carcinoma



Journal of Surgical Oncology 105(6): 548-552



Recurrent laryngeal nerve lymph nodes (RLN LNs) are considered sentinel nodes for cervical LN metastases of esophageal cancer. Surgery is the treatment of choice, but whether three-field lymph node dissection (3FL), which includes cervical LN dissection, or 2FL, which does not, should be performed is controversial. We retrospectively analyzed medical records of 200 patients with esophageal cancer who underwent 3FL from January 2000 to August 2010, focusing on LN status. We also compared survival rates between these patients and those who underwent 2FL. The rate of cervical LN metastases did not differ significantly between RLN LN+ (for metastasis) and RLN LN- 3FL groups. However, in a subgroup of patients with middle/lower thoracic esophageal tumors, cervical LN metastases were significantly more common in patients with positive rather than negative RLN LNs. Survival did not differ after 3FL versus 2FL in general. However, 3FL was associated with longer survival than 2FL in patients with RLN LN positivity and either lower thoracic esophageal tumors or more than four abdominal/thoracic LN metastases. Metastasis to RLN LNs is a reliable indicator of cervical LN metastasis in middle/lower thoracic esophageal cancer, while 3FL offers survival benefit over 2FL in certain patient subgroups.
