Özet
Background: To determine the contribution to diagnostic rates of the evaluation of the sonographic characteristics of lymph nodes with EBUS together with vascularity. Methods: In the present study, patients who underwent the Endobronchial ultrasound (EBUS) procedure were evaluated retrospectively. Patients were classified as benign or malignant by using the sonographic features of EBUS. EBUS-Transbronchial Needle Aspiration (TBNA) confirmed histopathologically with lymph node dissection or in cases where no disease progression was observed clinically or radiologically in at least 6 months of follow-up. Malignant lymph node diagnosis was based on histological examination. Results: Evaluation was made of 165 patients comprising 122 (73.9%) males and 43 (26.1%) females with a mean age of 62.0 ± 10.7 years. Malignant disease was diagnosed in 89 (53.9%) cases and benign disease in 76 (46.1%) cases. The success level of the model was seen to be approximately 87%. The Nagelkerke R2 value was calculated as 0.401. The probability of malignancy increased 3.86-fold (95% CI: 2.61-5.11) in lesions of diameter ≥20 mm compared to lesions <20 mm, 2.58-fold (95% CI: 1.48-3.68) in lesions not determined with central hilar structure (CHS) compared to those determined with CHS, 6.85-fold (95% CI: 4.67-9.03) in lymph nodes observed with necrosis compared to those without necrosis, and 1.51-fold (95% CI: 0.41-2.61) in lymph nodes with a vascular pattern (VP) score of 2-3 compared to those with a VP score of 0-1. Conclusion: Visualization of coagulation necrosis with EBUS-B mode and the determination of VP 2-3 in power Doppler mode were seen to be the most important criteria of malignancy.
