THE RISK RATIO, T1N1/T1N0, CORRELATES WITH TUMOR PROGNOSTIC MARKERS, HOST FACTORS, AND OVERALL SURVIVAL IN BRONCHOGENIC LUNG CANCER: A SEER (SURVEILLANCE, EPIDEMIOLOGY, AND END RESULTS) STUDY

PURPOSE: Bronchogenic carcinoma, low stage, presents as an intraparenchymal tumor (T1) that may involve bronchial/hilar lymph nodes (N1). This study investigates whether a risk ratio, T1N1/T1N0, derivable from the SEER data set, correlates with tumor features and host factors, predicts overall survival, and may be an indicator of tumor biologic potential.
