Abstract

Purpose: To survey ultrasonographic characteristics suggested benign and malignant cervical lymph node metastasized
from EC methods (esophagus cancer). To find out the values of FNA in diagnosis of metastatic cervical lymph node from EC.
Materials and Methods: 20 patients were diagnosed EC and ultrasound detected suspiciously malignant cervical lymph node,
from 4/2012 to 6/2013. The patients were surveyed: Mode 2D, FNA, cytopathology in Hue Central Hospital. We divided the diagnosis into 2 groups: benign and malignant group.
Results: In 20 patients with cytology, 8 cases are diagnosed malignant lymph node metastasized from EC. The remains, 12 patients are diagnosed with benign lymph node: lymphadenitis. In our research, the signs suggest malignant lymph node in sonography: hypoechonic, heterogeneous, loss of the fatty hyperechoic hilum, ill-defined border, size about 10mm in diameter (short axis), round-shaped, greater numbers. Se= 80%, Sp= 100%, PPV= 100%, no false negative cas.
Conclusion: The combination of ultrasound and FNA is valuable in the diagnosis of suspected malignant lymph node in the neck, metastasized from EC. It is a safe and simple method for selected patients which allows diagnosis and staging in a single step.
