Fig 1 Cancer-specific survival curve (solid line) for patients with early stage (I and II) non-small cell lung cancer. (A) Representative (dotted) tangent lines demonstrate that the risk of death (slope of the curve) changes throughout the course of follow-up. (B) For example, the risk of dying of cancer in the subsequent 5 years is greater for patients at the time of cancer diagnosis (Δ1) than for patients 3 years after diagnosis (Δ2). Data from the Surveillance, Epidemiology, and End Results Database (1988–2005).

Fig 3 Five-year cancer-specific survival rates, with error bars indicating 95% confidence intervals (vertical axis) conditioned on surviving 0 to 10 years after lobectomy (horizontal axis).

Fig 4 Competing risks curves for the probability of the following outcomes: surviving (solid line), cancer-specific mortality (dotted line), cardiovascular disease-specific mortality (dashed line), and death from other causes (dotted and dashed line) at (A) the time of diagnosis and conditioned on living (B) 1 year, (C) 3 years, (D) 5 years, and (E) 7 years after lobectomy. The p values are for tests comparing the conditional probabilities of cancer-specific and cardiovascular disease-specific mortality within 5 years.

Fig 5 Analysis demonstrating the year at which the probability (P) of dying of cancer is not significantly different (p > 0.01) from the probability of dying of cardiovascular (CV) disease (vertical axis) for each of the following subgroups: (A) age, (B) race, (C) sex, (D) pathologic tumor (T) stage, and (E) histology. (Adeno = adenocarcinoma; BAC = bronchoalveolar carcinoma; squam = squamous cell carcinoma.)
