摘要

Because surgical therapy is the standard curative approach to non-small cell lung cancer, preoperative staging must be accomplished efficiently and accurateh Two recent articles address the issues of appropriate preoperative evaluation. Whit and coworkers suggest that computed tomographic (CT) scanning of the chest is nc sensitive or specific enough in the diagnosis of mediastinal invasion to alone preclud lung resection. In contrast, Ferrigno and colleagues found CT scanning of the brain t be a reliable technique in identifying brain metastasis, but brain metastasis could nc be predicted by either cell type or the presence of neurologic symptoms.
