Minority-serving hospitals had similar survival after liver cancer surgery


 

FROM DDW 2020

Overall survival after liver cancer surgery was similar regardless of whether patients were treated at minority-serving hospitals or at hospitals with proportionally fewer African American or Hispanic patients, investigators have found.

“[T]reatment of racial minorities is largely restricted to a subset of hospitals, often referred to as minority-serving hospitals. We sought to examine whether racial and ethnic minorities with hepatocellular carcinoma receive their surgical care at minority-serving hospitals, and whether treatment at minority-serving hospitals is associated with differences in overall survival,” explained Winta T. Mehtsun, MD, MPH, of Dana-Farber Cancer Institute in Boston and associates in an abstract released as part of the annual Digestive Disease Week.®

Hepatocellular carcinoma continues to have a low 5-year survival rate and exhibits marked racial and ethnic disparities in diagnosis, treatment, and outcomes. In a recent study of Surveillance Epidemiology and End Results (SEER) data, African American patients with hepatocellular carcinoma were significantly younger at diagnosis, were more likely to have metastatic disease, and were less likely to receive surgical treatment compared with whites (Am J Prevent Med 2018;55:S40-48). Among patients with early-stage liver cancer, Hispanic and African American patients are less likely to receive curative therapy and die sooner, on average, than do other patients (Clin Gastroenterol Hepatol. 2019;17:551-9).

Minority-serving hospitals also have improved significantly less over time on measures of critical care, length of stay, and mortality, but whether these issues extend to hepatocellular carcinoma remains unclear. Therefore, Dr. Mehtsun and her associates studied all 2,609 patients in the National Cancer Database who received surgical resection (not transplantation or local therapy) for nonmetastatic hepatocellular carcinoma between 2004 and 2014. They compared survival at minority-serving hospitals – those in the top 10% based on the proportion of patients who were African American or Hispanic – with survival at other hospitals.

“There was no association between minority-serving hospital and overall survival,” the researchers reported (multivariable hazard ratio for death, 0.89; 95% confidence interval, 0.72-1.11). In contrast, survival was significantly shorter among patients with more advanced disease (HR, 2.5; 95% CI, 2.1-2.8), patients who were treated at a community cancer program (HR, 1.7; 95% CI, 1.3-2.4), and patients whose Charlson Comorbidity Index was greater than 2 (HR, 1.2; 95% CI, 1.1-1.4).

Stage at diagnosis, comorbidities, and sex were not significantly related to hospital type, the investigators noted. A total of 298 patients (11%) were treated at minority-serving hospitals. Patients treated at minority-serving hospitals were significantly more likely to be uninsured (11% vs. 4% at other hospitals) and significantly less likely to be treated at an academic center (55% vs. 69%; both P less than .001).

Dr. Mehtsun reported having no relevant conflicts of interest.
