This document summarizes a study examining factors that predict outcomes for patients with non-small cell lung cancer who undergo lobectomies or pneumonectomies. Neural networks, Cox regression, and bootstrap simulation were used to analyze data on 511 patients. The analysis found that nodal status (N0-2), tumor growth characteristics, surgery type, grade (G1-3), histology, radiotherapy, adjuvant therapy, and 16 blood factors best predicted whether patients would be 5-year survivors or experience cancer mortality within 5 years of surgery. Neural networks correctly predicted patient outcomes in 99.8% of cases.
