Patterns of lymph node metastasis and survival for upper esophageal squamous cell carcinoma.

AbstractBACKGROUND:
This study evaluated the clinical results, nodal metastatic patterns, and overall efficacy of esophagectomy with three-field lymph node dissection for upper esophageal squamous cell carcinoma (SCC).
METHODS:
Between 2001 and 2008, esophagectomy was performed in 497 esophageal cancer patients, of whom 93 underwent esophagectomy with three-field lymph node dissection, without neoadjuvant treatment for upper esophageal SCC.
RESULTS:
Of these 93 patients, 91 (97.8%) were men, the median age was 65.0 years, and 82 (88.2%) underwent R0 resection with curative intent. In-hospital mortality was 4.3%. Pathologic T N M stages were stage I, 8.6%; stage II, 16.1%; stage III, 75.3%; and stage IV, 0%. The mean numbers of total lymph nodes dissected and, of those, total metastatic lymph nodes per patient were 61.7±18.2 and 4.7±7.0, respectively. Metastases occurred to the recurrent laryngeal lymph nodes in 43.3%, to the cervical lymph nodes in 46.2%, and to abdominal lymph nodes in 24.7% of patients. Overall 5-year and disease-free survival rates were 43.5% and 34.3%, respectively, and were 50.1% and 37.6%, respectively, for R0 resection.
CONCLUSIONS:
Recurrent laryngeal lymph node chains are those most commonly affected by nodal metastasis, and the prevalence of cervical lymph node involvement is high, at more than 40%. Esophagectomy with three-field lymph node dissection in patients with upper esophageal SCC can be performed with acceptable morbidity and mortality. Curative R0 resection for upper esophageal SCC achieved a satisfactory 5-year survival rate.
