BACKGROUND: Most surgeons consider esophageal carcinoma with lymph node involvement a systemic disease. However, it is possible that the disease may be localized in the earlier phases of lymphatic metastasis. The distribution of involved lesions in the initial phase of lymph node metastasis has not been thoroughly investigated yet. METHODS: Among 329 patients that underwent curative (R0 International Union Against Cancer [UICC]) esophagectomy with systematic mesoesophageal dissection, 51 cases of patients with only 1 involved lymph node (solitary involvement) were retrospectively investigated and compared with patients with multiple involved lymph nodes. The regional lymph nodes were divided into the thoracocervical junction group (lower deep cervical and recurrent nerve lymph nodes), perigastric group, and intrathoracic group. RESULTS: Lymph node involvement was limited to a solitary lymph node in 46% of lymph node positive patients with esophageal carcinoma confined to the wall (T1 and T2, UICC) and in 17% of lymph node positive patients with cancer that invaded the extramural layer (T3 and T4, UICC). Of patients with solitary involvement, 82% had a positive thoracocervical junction or perigastric lymph node. The 5-year survival rate in solitary involvement cases was 61%, and 65% when solitary involvement was not intrathoracic. Most of the 5-year survivors had involvement of a thoracocervical junction or perigastric lymph node and had not received systemic chemotherapy. CONCLUSIONS: Solitary involvement was not rare and not directly associated with a disseminated disease. Solitary involvement was commonly located in the thoracocervical junction or abdomen that are accessible without thoracotomy. Systematic dissection of the regional lymph nodes including thoracocervical junction and perigastric groups is recommended for resectable esophageal carcinoma at this time. However, less extensive dissection may be performed in selected cases if the sentinel lymph node concept proves valid. Copyright 2000 American Cancer Society.
