Patients diagnosed with hepatocellular carcinoma (HCC) between 2004 and 2015 were identified from the SEER-Medicare linked database. Information on county-level upward economic mobility was obtained from the Opportunity Atlas. The impact of economic mobility on early-stage diagnosis (stage I or II) and receipt of surgical treatment was analyzed and stratified by race/ethnicity.
Results:
Among 10,987 patients diagnosed with HCC, median age was 73 (IQR, 68-79) and a majority was male (n=7,502, 68.3%). Almost two thirds of patients were White (n=7,233, 65.8%), while other patients were either Black (n=1,059, 9.6%) or did not identify as either White or Black (n=2,695, 24.5%). Although most patients were diagnosed with stage I (n=4,467, 40.7%) or stage II disease (n=1,843, 16.8%), only a small minority of patients underwent surgical resection (n=930, 8.5%). On multivariable analysis, residing in a high versus low economic mobility county was not associated with stage at diagnosis (OR 1.10, 95%CI 0.99-1.23; p=0.09); however, patients who lived in high upward mobility communities had 89% (OR 1.89, 95%CI 1.54-2.33; p< 0.001) increased odds to undergo surgical resection of HCC. Additional analyses stratifing patients by race/ethnicity demonstrated that patients residing in high upward economic mobility areas remained much more likely to receive surgery than patients from low upward economic mobility areas independent of race/ethnicity (White: OR 1.15, 95%CI 1.24-2.04; Black: OR 3.16, 95%CI 1.28-7.79; Other: 2.89, 95%CI 1.85-4.50).
Conclusions:
Despite similar HCC disease stage at diagnosis, patients residing in areas with higher upward economic mobility were markedly more likely to undergo surgical resection of HCC. The impact of county-level upward economic mobility on receipt of surgical treatment was independent of patient race/ethnicity.
