Multicenter StudyLocal recurrence after surgery for non-small cell lung cancer: a recursive partitioning analysis of multi-institutional data.
To define subgroups at high risk of local recurrence (LR) after surgery for non-small cell lung cancer using a recursive partitioning analysis (RPA). ⋯ The risk of LR was similar in the primary and validation patient data sets. There was discordance between the 2 data sets regarding the clinical factors that best segregate patients into risk groups.
