Abstract
BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. It depends on angiogenesis for growth and metastasis. Vascular endothelial growth factor (VEGF), a growth factor for angiogenesis, is hoped to be a biomarker for the diagnosis of HCC and its development. AIM: The objective of the study is to determine the difference of VEGF levels among HCC patients based on barcelona clinic liver cancer (BCLC) staging. METHODS: A cross-sectional study was conducted at Haji Adam Malik General Hospital Medan, Indonesia between January and December 2018. Patients aged 18 years or older with HCC were enrolled using consecutive sampling method. Patients with cholangiocarcinoma, hemangioma, and liver metastasis were excluded from the study. The diagnosis of HCC was confirmed by triphasic computed tomography-scanning. Circulating VEGF levels were determined from serum specimen using Quantikine Human VEGF-enzyme-linked immunosorbent assay. All patients were grouped based on BCLC staging. Kruskal Wallis-H test was applied at 95% confidence interval. p < 0.05 was considered significant. RESULTS: Of 60 patients, 47 (78.3%) were male. Mean age of patients was 61.4 (SD11.7) years. Hepatitis B was the most common etiology (70.0%) of HCC. Based on BCLC staging, 25 (41.7%) patients were in stage C. Median VEGF level was 951.25 pg/mL. There was a statistically significant difference in VEGF levels (p = 0.006) where patients in Stage C (1,009.6 pg/mL) and D (1,189.7 pg/mL) had higher VEGF levels compared to those in Stage A (578 pg/mL). CONCLUSION: There was a statistically significant difference of VEGF levels among HCC patients based on BCLC staging.
