Importance of clinical staging in limited small-cell lung cancer: a valuable system to separate prognostic subgroups. The University of Toronto Lung Oncology Group.

Abstract

Using simple clinical staging techniques, we were able to identify a subgroup of patients with very limited SCLC who had a significantly better prognosis. We recommend that randomized clinical trials stratify patients according to the presence or absence of clinically detectable mediastinal lymphadenopathy.
