title: The impact of ultrasonography-guided fine needle aspiration of no palpable supraclavicular lymph nodes on diagnosis and staging in advanced lung cancer.
abstract: Diagnosis and accurate staging of lung cancer is essential for selection of appropriate curative or palliative therapy and affects patient prognosis. Both invasive and non-invasive procedures are used for this purpose. We aimed to assess the frequency of no palpable supraclavicular lymph node metastases in lung cancer patients with enlarged mediastinal lymph nodes, and their impact on diagnosis and staging using ultrasound in this study. Lung cancer patients with no palpable supraclavicular lymph nodes and at least 2 enlarged mediastinal lymph nodes on computerized tomography underwent supraclavicular ultrasound examination. Ultrasound-guided fine needle aspiration (US-guided FNA) was performed when enlarged lymph nodes were present. Supraclavicular lymph node metastasis was confirmed cytologically via US-guided FNA in 16 (40%) of 40 patients. Upper paratracheal lymphadenomegaly was significantly higher in patients with supraclavicular metastases than in those without. No statistical significant differences were observed in the stage, cell types, and metastases of patients with or without supraclavicular metastases. In 3 patients US-guided FNA was used for diagnosis. More than one-third of lung cancer patients with enlarged mediastinal lymph nodes had supraclavicular lymph node metastases in present study. US-guided FNA is an easier, safer, and less invasive procedure than standard techniques used to diagnose lung cancer patients with enlarged mediastinal lymph nodes.
