Abstract
As the leading cause of death worldwide, lung cancer has proven itself incurable in the advanced stages. For early stages, endobronchial ultrasounds transbronchial needle aspiration (EBUS-TBNA) is now considered the standard to assess mediastinal lymph node, to define the multimodality therapeutic approach. In recent years, EBUS-TBNA has extended its use also in the metastatic and locally recurrent disease. New molecules, with specific mutations that give resistance to current target therapies, have made re-biopsy at disease progression an important assessment, with therapeutic and clinical implication. Here we present the oncologist's point of view on EBUS-TBNA in the staging process, at recurrence and progression.
