Summary

Lung cancer is a prevalent cause of cancer-related mortality on a global scale. Appropriate staging of lung cancer is of paramount importance, as it customizes treatment and predicts prognosis. Fludeoxyglucose-18 (FDG) positron emission tomography (PET) combined with low dose contrast computed tomography (CT) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are two diagnostic modalities widely used in the field of staging \& diagnosis of lung malignancies, the former depends on image analysis while the later enables real-time sampling of lymph nodes under sonographic guidance with concurrent cytological examination. The present research aims to compare the diagnostic and staging accuracies of (EBUS-TBNA) versus FDG-PET /CT as two diagnostic modalities in patients with suspected lung malignancies. However as a secondary outcome this study aims at monitoring the possible complications arising post EBUS-TBNA procedure.

Detailed description

Lung cancer is a prevalent cause of cancer-related mortality on a global scale. Appropriate staging of lung cancer is of paramount importance, as it customizes treatment and predicts prognosis. Fludeoxyglucose-18 (FDG) positron emission tomography (PET) combined with low dose contrast computed tomography (CT) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are two diagnostic modalities widely used in the field of staging \& diagnosis of lung malignancies, the former depends on image analysis while the later enables real-time sampling of lymph nodes under sonographic guidance with concurrent cytological examination. Objective: To compare the diagnostic and staging accuracy of convex probe EBUS-TBNA versus FDG - PET/CT as two diagnostic modalities in diagnosis of suspected lung cancer \& staging of concurrent mediastinal lymphadenopathy Patients and Methods: This prospective, interventional cohort research was performed on 40 cases with suspected lung malignancies. All cases were examined via FDG-PET/CT followed by convex probe EBUS-TBNA for diagnosis of suspected lung cancer \& staging of concurrent mediastinal lymphadenopathy.

Conditions

• Lung Malignancies
• Mediastinal Lymphadenopathy

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Endo bronchial ultrasound transbronchial needle aspiration(EBUS-TBNA)	Endo bronchial ultrasound enables visualization of parabronchial structures throughout a bronchoscopic procedure. EBUS-TBNA, which is considered a less invasive diagnostic tool for nodal staging compared to mediastinoscopy, allows real-time, direct sampling of hilar \& MLNs under sonograghic guidance with concurrent cytological and histopathological examination
