Supraclavicular lymph node metastasis in esophageal carcinoma: a topic of ongoing controversy.

ABSTRACT: Lymph node metastasis is an important prognostic factor in esophageal carcinoma (EC). Currently, there are no consensus-based staging methods for EC with supraclavicular lymph node (SCLN) metastasis. In this review, we present a summary of several classification methods of the SCLNs and highlight their differences in anatomic definitions. Then, we analyze the lymphatic drainage of the SCLNs from esophagus and the distribution patterns of the SCLNs metastasis from EC. Moreover, we discuss the prognostic influence and different staging methods of the SCLN metastasis. In summary, the variations in different classification methods make the SCLNs confusing for clinical application. A standardized and precise definition of the SCLNs should be established urgently for EC. SCLNs can drain lymphati
