Metode: Sebanyak 221 sampel kelenjar getah bening dari 40 pasien yang memenuhi kriteria penelitian studi potong lintang yang menjalankan pemeriksaan CT scan leher dengan kontras, dilakukan operasi diseksi leher, dan memiliki hasil pemeriksaan histopatologi dari tahun 2020 hingga 2023. Dilakukan analisis bivariat antara Node-RADS dan histopatologi menggunakan Mc Nemar test dan Kappa Cohen R.
Hasil: Sistem skoring Node-RADS memiliki nilai diagnostik yang tidak terlalu berbeda dengan histopatologi dengan p = 0,76. Sistem skoring Node-RADS memiliki nilai Kappa Cohen 0,725, masuk kedalam substansial agreement. Hasil rasio konkordans pada skoring Node-RADS yang tinggi sebesar 88,2%, Sensitivitas 87,3%, Spesifisitas 88,6%, Nilai Duga Positif 75,3%, Nilai Duga Negatif 94,5%, LR+ 7,2, LR- 14%.
Kesimpulan: Node-RADS memiliki nilai akurasi yang cukup tinggi dan dapat dipertimbangkan sebagai metode diagnostik metastasis kelenjar getah bening regio leher pada pasien dengan karsinoma sel skuamosa di kepala dan leher.
Objective: Assessing the accuracy of Node-RADS in diagnosing lymph node metastases in the neck region in patients with squamous cell carcinoma of the head and neck.
Method: A total of 221 lymph node from 40 patients who met the criteria for a cross-sectional research study, underwent a CT scan of the neck with contrast, neck dissection surgery, and had histopathological examination results from 2020 to 2023. Bivariate analysis was carried out between Node-RADS and histopathology using the McNemar test and Cohen's Kappa (κ).
Results: Node-RADS scoring system had a diagnostic value that was not significantly different from histopathology, with p = 0.76. The Node-RADS scoring system has a Cohen's Kappa value of 0.725, indicating substantial agreement. The concordance ratio results for Node-RADS scoring were high, with 88.2% concordance, a sensitivity of 87.3%, specificity of 88.6%, positive predictive value of 75.3%, negative predictive value of 94.5%, LR+ of 7.2, and LR- of 14%.
Conclusion: Node-RADS has a high accuracy value and can be considered as a diagnostic method for lymph node metastases in the neck region in patients with squamous cell carcinoma of the head and neck."
