Abstract

OBJECTIVE:

To determine the impact of recent relocation prior to a cancer diagnosis on cancer-specific outcomes.

METHODS:

We identified 272,718 patients with two different entries in the Surveillance, Epidemiology, and End Results database within 3years of each other. Those who had relocated to a different county between entries were identified and we determined the risk of stage IV disease or cancer-specific mortality among relocators and non-relocators after adjusting for other patient-specific demographic and clinical factors.

RESULTS:

A total of 4639 (1.7%) patients relocated to a new county within 3years prior to a second cancer diagnosis and 268,079 (98.3%) patients did not. Patients who had relocated to a new area were more likely to be diagnosed with stage IV cancer (25.2% vs. 20.8%; adjusted odds ratio=1.27; 95% confidence interval [CI], 1.18-1.37; P<0.001), and had an increased risk of 10-year cancer-specific mortality (20.9% vs. 17.9%; adjusted hazard ratio 1.26; 95% CI, 1.17-1.36; P<0.001).

CONCLUSION:

These results suggest that recent relocation to a new county prior to a cancer diagnosis is associated with an increased risk of late-stage presentation and worse cancer-specific mortality.
