Figure legends
Figure 1. The predicted probability of lung metastases increased when tumor size . For each10 mm increase in tumor size, the odds of having lung metastases increases by 6.6%, controlling for other covariates.
Figure 2. The cumulative mortality of patients with or without lung metastases. The patients with lung metastases had a higher rate of cumulative mortality.
Figure 3. The cumulative mortality of patients in different race and primary site. African Americans had a high cumulative mortality of 60%, while white people only had a rate of 40%(Figure 3). The tumors’ primary site of patient didn’t display a significant difference in cumulative mortality.
