Diabetes Mellitus and Prediabetes in Patients with Hepatocellular Carcinoma in a Tertiary Philippine Hospital.

BACKGROUND

Diabetes mellitus (DM) has been shown to be associated with an increased risk for hepatocellular carcinoma (HCC). DM and obesity are coexisting conditions that can increase the risk and severity of nonalcoholic fatty liver disease (NAFLD), leading to HCC even in the absence of cirrhosis. With the rising incidence of HCC and DM worldwide, it is important to identify the clinical characteristics of individuals with DM among those with HCC in our local setting.

OBJECTIVES

To determine the prevalence of DM among Filipino patients with HCC at our institution, determine their demographic and clinical profile, and compare the characteristics of HCC patients with and without DM.

METHODOLOGY

This is a retrospective, analytical, cross-sectional study involving patients with HCC seen at The Medical City's Center for Liver Disease Management and Transplantation from January 2010 to December 2014. A chart review was conducted and patients were grouped according to the presence or absence of DM. Data on demographics, body mass index (BMI), comorbidities, social and family history, risk factors for liver disease, and laboratory test results were gathered. STATA 12.0 was used for data analysis.

RESULTS

We included 180 patients with HCC in the analysis. The prevalence of type 2 DM and prediabetes was 52.78%. The median age of patients with DM and prediabetes was 65 years, and 58 years for patients without DM (p=0.002). The average BMI was 27.35 + 4.68 for patients with DM, and 25.04 + 5.11 for those without DM (p=0.002). Among the patients without DM, 50.59% had hepatitis B virus (HBV) infection compared to 24.21% of patients with DM (p=0.000). Twenty one percent of patients with DM had cryptogenic cirrhosis compared to 8.24% of patients without DM (p=0.016). Patients with DM had a higher proportion of hypertension (66.32% vs. 42.35%, p=0.001) and dyslipidemia (48.42% vs. 10.59%, p=0.000).

CONCLUSION

The prevalence of DM and prediabetes among HCC patients is higher in our institution compared to findings from previous studies. HCC patients with DM were older, and had increased BMI, higher proportion of hypertension and dyslipidemia, lower incidence of HBV infection, and higher incidence of cryptogenic cirrhosis.
