MA13.06 - Endosonography with Lymph Nodes Sampling for Restaging the Mediastinum in Lung Cancer: A Systematic Review and Pooled-Data Analysis (ID 11918)

Background
Mediastinal restaging after induction treatment is still a difficult and controversial issue. We aimed to investigate the diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for restaging the mediastinum after induction treatment in patients with lung cancer.

Embase and PubMed databases were searched from conception to July 2017. Data from relevant studies were analyzed to assess sensitivity and specificity of EBUS-TBNA and EUS-FNA, and to fit the Hierarchical Summary Receiver-Operating Characteristic curves.

A total of nine studies consisting of 542 patients fulfilled the inclusion criteria. All patients were restaged by EBUS-TBNA, EUS-FNA or both. Negative results were confirmed by subsequent surgical approaches. There were no complications reported during any endosonography approaches reviewed. The pooled sensitivities of EBUS-TBNA and EUS-FNA were 66%(95% CI, 60%-72%) and 73%(95% CI, 52%-87%), respectively; and specificities were 100%(95% CI, 98%-100%) and 99%(95% CI, 90%-100%), respectively. The area under the HSROC curves(AUC) were 0.84(95% CI, 0.81-0.87) for EBUS-TBNA and 0.99(95% CI, 0.98-1) for EUS-FNA. Moreover, for patients who received chemotherapy alone, the pooled sensitivity of endosonography with lymph node sampling for restaging was 69% (95% CI, 63%-75%), and specificity was 100% (95% CI, 97%-100%); and for patients who received chemoradiotherapy, the results seemed similar with sensitivity of 65% (95% CI, 50%-78%) and specificity of 100% (95% CI, 96%-100%).

Endosonography with lymph node sampling is an accurate and safe technique for mediastinal restaging of lung cancer. For nondiagnostic results, a further more invasive approach should be thoroughly considered.
