Introduction: Metastatic spread of lung cancer to supraclavicular lymph nodes is considered distant metastasis for treatment purposes. Detection of supraclavicular lymph node metastasis in patients with lung cancer serves for tissue diagnosis by itself and also helps avoid more invasive biopsy from the primary lung mass itself. Ultrasonography of the lower neck can detect supraclavicular lymph nodes before they are palpable and can also be used for safe sampling of these lymph nodes. The aim of this study was to find out the prevalence of metastatic supraclavicular lymph nodes among patients with lung carcinoma in a tertiary care centre.
Methods: A descriptive cross-sectional study done in a tertiary care center, carried out from 15 September 2019 to 14 September 2020. Ethical approval was obtained from the Institutional Review Committee (Reference number: 84(611)E2/076/077). The study was done among 92 patients with biopsy-proven lung cancer (lung mass or supraclavicular lymph node biopsy) who were referred for evaluation, and/or percutaneous transthoracic biopsy. Convenience sampling method was used. Point estimate and 90% Confidence Interval were calculated.
Results: Among 92 patients with proven lung cancer, metastatic supraclavicular lymph nodes were seen in 13 patients (14.10%) (8.17- 19.73, 90% Confidence Interval). Among 13 patients with metastatic lymph nodes, 9 (69.23%) had palpable supraclavicular lymph nodes. The majority 11 (84.61%) had round-shaped lymph nodes. All metastatic lymph nodes showed loss of echogenic fatty hilum. A total of 12 (92.30%) metastatic lymph nodes showed a peripheral disorganized pattern of vascularity.
Conclusions: The prevalence of metastatic supraclavicular lymph nodes was lower than in similar studies done in international settings.
