Inpatient mortality outcomes of patients with hepatocellular carcinoma with congestive heart failure: A nationwide retrospective cohort study.

Abstract

e16256 Background: Chronic conditions create challenges in improving outcomes and treatment strategies for cancer patients. In the general population, for example, congestive heart failure (CHF) has been associated with poor cardiovascular health and thus increased mortality. However, its prognostic implications in patients with hepatocellular carcinoma (HCC) are less clear despite the physiological connection of the cardiohepatic system. This study aims to elucidate the relationship between CHF and mortality among HCC patients, offering insights that could inform clinical management strategies and improve care. Methods: The 2017 – 2019 versions of the National Inpatient Sample (NIS) database from the Healthcare Cost and Utilization Project (HCUP) were used to acquire the sample population. ICD-10 codes were used to identify diagnoses and procedures. The main sample population consisted of all patients diagnosed with HCC. A multivariate regression model was used (adjusted for age, sex, race, median household income based on patient ZIP code, Charleston Comorbidity Index score, hospital region, hospital teaching status based on rural/urban setting) to calculate the adjusted odds ratio (aOR) for outcomes. First, the association between CHF and inpatient outcomes was examined. Then mortality was calculated for HCC patients receiving therapeutic interventions (chemoradiation, liver transplant, radiation, or immunotherapy) based on CHF status. Results: There were 29,396 patients with HCC. Of this amount, 3,810 patients (13%) had CHF diagnoses. For inpatient procedures, 1,120 patients (3.8%) underwent a liver transplant, 265 (0.9%) received chemotherapy, 2 (0.01%) received immunotherapy, and 5 (0.02%) received radiation therapy. The cohort of CHF patients was found to be older than non-CHF patients (70.2 ± 0.3 years and 64.3 ± 0.2 years, respectively, with p < 0.001). The multivariate regression analysis for the entire sample showed that the adjusted odds of mortality for HCC patients with CHF was 0.92 times that of not having CHF but not significant (95% CI 0.8 – 1.07, p = 0.3). The analysis was then applied to HCC patients receiving one of the four treatments during their hospitalization. Results showed that the CHF cohorts had increased odds of mortality if they received a liver transplant (aOR 20.3, 95% CI 2.5 – 165.7; p = 0.005) or chemotherapy (aOR 338.4, 95% CI 10.0 – 11428.9; p = 0.001). Conclusions: Having CHF is not a significant predictor of mortality in patients with HCC. However, when considering HCC patients undergoing liver transplantation, having comorbid CHF significantly carried about a 20-fold odds in mortality. In addition, HCC patients receiving chemotherapy had a 338-fold odds of death if they have CHF. Thus, careful consideration and planning must be taken into account to optimize patients’ cardiac status when considering treatment options.
