Core Tip

Core tip: The evidence is evolving for the role of positron emission tomography-computed tomography (PET-CT) in the management of non-small cell lung cancer (NSCLC). Available literature supports the use of PET-CT in the staging of NSCLC to have better disease staging (assessment of mediastinal and extra-thoracic disease). Detection of abnormal mediastinal nodes at various basins is the potential advantage of PET-CT for better targeted biopsy and it may lead to reduction in futile surgical interventions. The role of PET-CT in the prediction and assessment of response to neoadjuvant therapy needs further studies.
