Background/AimsTransarterial chemoembolization (TACE) is performed for single hepatocellular carcinoma (HCC) that are not eligible for surgery or ablation therapy. We investigated the clinical outcomes of patients with a single HCC ≤ 5 cm treated with TACE.MethodsThis study analyzed 175 consecutive patients who underwent TACE as an initial treatment for single HCC ≤ 5 cm. Predictive factors for complete response (CR), recurrence after CR, and overall survival (OS) were evaluated.ResultsTotal 119 patients (68%) achieved CR after TACE. Tumor size < 3 cm and hepatitis B virus infection were significant predictors of CR (p < 0.05). Recurrent HCC was detected in 73 patients (61.3%) after CR. Age > 65 years and absence of liver cirrhosis were predictive factors for non-recurrence after CR (p < 0.05). The OS for all patients was 80.7 ± 5.6 months, and the 1-, 3-, and 5-year OS rates were 88.1%, 64.8%, and 49.9%, respectively. In multivariate analysis for OS, CR (hazard ratio [HR], 0.467; 95% confidence interval [CI], 0.292 to 0.747) and Child class A (HR, 0.390; 95% CI, 0.243 to 0.626) were significant factors. The OS for the CR and Child class A group were 92 and 93.6 months, respectively, and that of the non-CR and Child B, C group were 53.3 and 50.7 months, respectively (p < 0.001).ConclusionsTACE can be a valid treatment in patients with a single HCC ≤ 5 cm not suitable for curative treatment, especially in patients with Child class A and CR after TACE.

Background and ObjectivesCirculating endothelial progenitor cells (EPCs) play a key role in the maintenance of endothelial homeostasis and promote vascular repair. A reduced number of EPCs and the functional activity have been associated with several cardiovascular risk factors. However, the relationship between the number of EPCs and circadian rhythm of the blood pressure (BP) remains unclear. The purpose of the present study was to evaluate the relationship between the circadian rhythm of the BP and EPCs in patients with essential hypertension.Subjects and MethodsA total of 45 patients with essential hypertension who were newly identified by outpatient BP measurements, underwent 24-hour ambulatory BP monitoring. Among the 45 patients with essential hypertension, 20 were classified as dippers (12 men and 8 women; mean age 48±14 years) and 25 as non-dippers (14 men and 11 women; mean age 52±18 years). The EPC count was isolated from the peripheral bloodstream and quantified by flow cytometry.ResultsThe baseline clinical characteristics were similar between the dipper and non-dipper hypertensive patients. The circulating EPCs were statistically reduced in the non-dipper patients as compared to the dippers (104±60 vs. 66±47 EPCs per 106 mononuclear cells, p=0.027). The circulating EPC level correlated positively with the circadian changes in the systolic and diastolic BP (r=0.435, p=0.003, and r=0.310, p=0.038, respectively).ConclusionThe present study demonstrated that the EPC count was reduced in the peripheral bloodstream in non-dipper hypertensive patients.

Background/AimsPractice guidelines recommend endoscopic band ligation (EBL) and endoscopic variceal obturation (EVO) for bleeding from esophageal varices and fundal varices, respectively. However, the optimal treatment for bleeding from cardiac varices along the lesser curvature of the stomach (GOV1) remains undefined. This retrospective study compared the efficacy between EBL and EVO for bleeding from GOV1.MethodsPatients treated by EBL or EVO via cyanoacrylate injection for bleeding from GOV1 were enrolled. Patients diagnosed with hepatocellular carcinoma or treated with endoscopic injection sclerotherapy were excluded.ResultsThe study included 91 patients treated for bleeding from GOV1. The mean age was 56.3±10.9 years (mean±SD), and 78 of them (85.7%) were men. Overall, 51 and 40 patients were treated with EBL and EVO, respectively. A trend for a higher hemostasis rate was noted in the EVO group (100%) than in the EBL group (82.6%, P=0.078). Varices rebled in 15 patients during follow-up. The rebleeding rate was significantly higher in the EBL group than in the EVO group (P=0.004). During follow-up, 13 patients died (11 in the EBL group and 2 in the EVO group); the survival rate was marginally significant between two groups (P=0.050). The rebleeding-free survival rate was significantly higher in the EVO group than in the EBL group (P=0.001).ConclusionCompared to EBL, EVO offered significantly lower rebleeding rates, significantly higher rebleeding-free survival rates, and a trend for higher hemostasis and survival rates. EVO appears to be the better therapeutic option for bleeding from GOV1.

Hepatocellular carcinoma (HCC) is the 2nd most common cause of cancer related death in Korea and well-known malignancy with poor prognosis. Sorafenib is the first-line molecular targeted agent in patients with extra-hepatic spread of HCC. However, complete response is extremely rare in patients treated with sorafenib and the disease control rate is only 43%. We report a 53-year-old man with advanced HCC with pulmonary metastasis who showed complete response by cytotoxic chemotherapy with doxorubicin and cisplatin with relatively tolerable adverse effects after failure of treatment with sorafenib.
