The objective of the treatment in stages III A and III B without pleural effusion should be both locoregional and distant disease control. We known that at least 80% of the patients had micrometastatic disease at the time of diagnosis, so that a treatment that is only local would be condemned to failure from the time it is suggested. Many clinical questions continue to exist and each step achieved is followed by a new diagnostic or therapeutic dilemma and is thus a fertile field for clinical research.
