title: [Metastatic involvement of regional lymph nodes and long-term results of the treatment of patients with cancer of the thoracic part of the esophagus].
abstract: The patients who underwent the radical operations for cancer of the thoracic esophagus were subdivided into three groups: group 1--patients with no metastatic involvement of the regional lymph nodes (N0); group 2--with enlarged regional lymph nodes because of their hyperplasia, but without metastatic involvement (NX); group 3--with metastatic involvement of the regional lymph nodes (N1). The best results of 5-year survival after radical operation (50.2%) were noted in patients with a tumor size less than 3 cm, infiltration of only muscular layer, high degree of cancer differentiation, without metastatic involvement of regional lymph nodes. In presence of metastases, the 5-year survival was 6.01%. Discovering at operation the enlarged lymph nodes is a poor prognostic sign, 5-year survival of these patients do not exceed 9%.
