Trends in prevalence of prognostic factors and survival in lung cancer patients from 1985 to 2004 at a tertiary care center.

ABSTRACT:

Background

After a prolonged period of increasing rates of lung cancer incidence and mortality for both men and women, incidence and mortality rates are decreasing in men and stabilizing in women. The goal of this study was to assess changes over 20 years in the prevalence of known risk factors for lung cancer and to elucidate possible predictors associated with lung cancer survival.

Methods

The study included a total of 908 patients with primary lung cancer referred to The University of Texas M.D. Anderson Cancer Center over three study periods 1985-1989 (N=392), 1993-1997 (N=216), and 2000-2004 (N=300). Detailed questionnaires were used to collect information from the patients. Hazard ratios were estimated by fitting a Cox proportional hazards model. Using the Kaplan-Meier
