Background/Aims
Phosphatase and tensin homolog (PTEN) is a known tumor suppressor gene that is downregulated in hepatocellular carcinoma (HCC). Here, we investigated the association between single nucleotide polymorphisms (SNPs) of PTEN and HCC development in patients with hepatitis B virus (HBV) infection.
Methods
Six SNPs of PTEN at positions rs1234221, rs1903860, rs1234220, rs1903858, rs2299941, and rs17431184 were analyzed in a development population (417 chronic HBV carriers without HCC and 281 chronic HBV carriers with HCC). PTEN rs1903858, rs1903860, and rs2299941 SNPs were further assessed for the development of HCC in a validation population of 200 patients with HBV-related liver cirrhosis.
Results
In the development population, PTEN rs1903860 C allele, rs1903858 G allele, and rs2299941 G allele were associated with a low risk of HCC. The haplotype A-T-A-A-A was associated with an increased risk of HCC (recessive model; odds ratio=2.277, 95% confidence interval [CI] =1.144-4.532, P=0.019). In the validation population, PTEN rs2299941 G allele was the only significant protective genetic polymorphism related to HCC development after adjustment for age and sex (hazard ratio=0.582, 95% CI =0.353-0.962, P=0.035).
Conclusions
These findings suggest that genetic polymorphisms in PTEN may affect HCC development in patients with chronic HBV infection.

AbstractAbstract PDF
A 52 year-old-male patient was admitted to our hospital due to hematemesis. Ten years ago, he had been diagnosed chronic hepatitis B and he was heavy alcoholics. He was in the state of SB tube insertion and we had esophagogastroduodenoscopy and found out cardiac varix bleeding and injected history1. On abdominal ultrasonograpy, large hypoechoic mass in left lobe of liver was noted and the mass invaded into hepatic vein, inferior vena cava (IVC), and right atrium. On hepatic arteriography, large hypervascular mass in left lobe of the liver and several small dodules in right lobe were noted. We performed chemoembolization to the nodules in right lobe but cannot performed to the lesion in left love due to arteriovenous shunt. We inserted the chemport catheter to proper hepatic artery and started the intra-arterial chemotherapy (IACT) with 5-FU 250 mg and cisplatin 10 mg for 5 days. After the second cycle of IACT, tumor thrombus in right atrium was disappeared and thrombus in IVC and tumor mass in left lobe were decreased in size. We believed that hepatocellular carcinoma of this patient should be sensitive to chemotherapy and planned the additional IACT treatment.
