RESUMO
PURPOSE: To evaluate the feasibility of transarterial therapy (transcatheter arterial chemoembolization and transcatheter arterial infusion) for patients with hepatocellular carcinoma and chronic kidney disease (CKD). MATERIALS AND METHODS: The study enrolled 35 patients who received transarterial therapy. The patients were classified into a CKD group (n = 10 nondialysis chronic kidney disease [NDCKD] and n = 9 end-stage renal disease [ESRD]) or a non-CKD group (n = 16). The survival rates between the two groups were compared using two different starting points: (a) from initial diagnosis of hepatocellular carcinoma and (b) from enrollment in the study. The tolerance of transarterial therapy in patients with CKD was evaluated by comparing the incidence of major adverse events. RESULTS: The 2-year and 5-year survival rates from initial diagnosis were 83.9% and 53.8% in the CKD group and 70.1% and 40.4% in the non-CKD group (P = .478). The corresponding 3-year survival rate from enrollment in the two groups was 25.6% and 41.2%, respectively (P = .995). The 2-year and 5-year survival rates from initial diagnosis were 70.1% and 40.4% in the non-CKD group, 90.0% and 39.4% in NDCKD patients, and 76.2% and 76.2% in ESRD patients (P = .380). The corresponding 2-year survival rates from enrollment in these groups were 54.9%, 48.0%, and 48.6% (P = .943). Severe contrast-induced nephropathy (n = 3) and late-onset death caused by cholesterol crystal embolism (n = 1) were observed in the NDCKD group. CONCLUSIONS: Transcatheter arterial chemoembolization is feasible in patients with CKD by instituting periprocedural hemodialysis with similar 2-year and 5-year survival compared with patients without CKD.

BACKGROUND: This study investigated the survival benefits of sorafenib vs. radiotherapy (RT) in patients with unresectable hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT) in the main trunk or the first branch. METHODS: Ninety-seven patients were retrospectively reviewed. Forty patients were enrolled by the Kanagawa Liver Study Group and received sorafenib, and 57 consecutive patients received RT in our hospital. Overall survival was compared between the two groups with PVTT by propensity score (PS) analysis. Factors associated with survival were evaluated by multivariate analysis. RESULTS: The median treatment period with sorafenib was 45 days, while the median total radiation dose was 50 Gy. The Child-Pugh class and the level of invasion into hepatic large vessels were significantly more advanced in the RT group than in the sorafenib group. Median survival did not differ significantly between the sorafenib group (4.3 months) and the RT group (5.9 months; P = 0.115). After PS matching (n = 28 per group), better survival was noted in the RT group than in the sorafenib group (median survival, 10.9 vs. 4.8 months; P = 0.025). A Cox model showed that des-γ-carboxy prothrombin <1000 mAU/mL at enrollment and RT were significant independent predictors of survival in the PS model (P = 0.024, HR, 0.508; 95% CI, 0.282 to 0.915; and P = 0.007, HR, 0.434; 95% CI, 0.235 to 0.779; respectively). CONCLUSIONS: RT is a better first-line therapy than sorafenib in patients who have advanced unresectable HCC with PVTT.

BACKGROUND: To determine the value of early alterations of the tumor markers α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) for predicting the outcomes of patients with advanced hepatocellular carcinoma (HCC) who receive sorafenib. MATERIALS AND METHODS: Tumor response, overall survival (OS), and progression-free survival (PFS) were retrospectively analyzed in 59 patients with advanced HCC. Serum AFP and DCP were examined for early elevation within 4 weeks after the initiation of sorafenib. An increase in AFP was defined as AFP of more than 20%, and an increase in DCP was defined as more than two-fold higher level than the baseline. The relationship of the clinical characteristics, laboratory data at baseline, and early elevations of AFP and DCP with disease progression was analyzed. RESULTS: The median OS and PFS were 11 and 3.3 months, respectively. The rate of progressive disease (PD) was 54%, and an early increase in AFP was significantly related to PD (P=0.006) and was a significant independent predictor of both poorer OS and PFS (P<0.001, hazard ratio, 4.14; 95% confidence interval, 1.946-8.811; and P=0.001, hazard ratio, 2.852; 95% confidence interval, 1.524-5.337, respectively). There was no association between early increase in DCP and clinical outcomes. CONCLUSION: Early increase in AFP predicted PD and poorer survival and may thus be a useful biomarker in patients with advanced HCC who receive sorafenib.

UNLABELLED: Some clinical studies confirmed the efficacy and safety of sorafenib in advanced hepatocellular carcinoma(HCC), for which the standard initial dose is 400 mg twice daily. However, it is unclear whether this dosage is tolerable for patients with a low body surface area(BSA). We retrospectively analyzed the difference in efficacy and safety of sorafenib between patients with low BSA and high BSA. METHOD: From July 2009 to June 2010, 64 patients with Child-Pugh grade A cirrhosis receiving sorafenib at 4 institutions were enrolled, and divided into two groups(BSA<1. 6m2 and ≥1. 6m2). RESULTS: In BSA<1. 6m2 and BSA≥1. 6m2 groups, grade 3-4 adverse events were observed in 64. 3% and 55. 3% of patients, respectively, and subsequent discontinuation was 38. 5% and 24. 2%, respectively indicating poor compliance in the former group. The disease control rate was 33. 3% and 37. 8%, the median time-to-radiological progression(TTRP)was 2. 1 months and 3. 6 months(p=0. 003), and median survival time was 6. 6 months and 11. 2 months in low BSA and high BSA groups(p=0. 10), respectively. Multi-variate analysis showed that poor prognostic factors for TTRP were ECOG performance status of ≥1 and BSA<1. 6m2. CONCLUSION: Standard dosage seems intolerable for patients with low BSA, and results in poor prognosis.

BACKGROUND AND AIMS: Sorafenib is currently in clinical use as an oral multikinase inhibitor that blocks tumor growth and cell proliferation in advanced hepatocellular carcinoma (HCC). It has been demonstrated in a translating study that sorafenib had a beneficial effect on portocollateral circulation in cirrhotic animals with portal hypertension. This study was prospectively performed to evaluate the portal hemodynamic effect of sorafenib in patients with advanced HCC using duplex Doppler ultrasonography (DDU). METHODS: Twenty-five Child-Pugh class-A patients with advanced HCC had received sorafenib at a dose of 400 mg twice daily. Primary outcomes were changes in portal venous area (PVA; cm(2)) as seen by using DDU before and after a 2-week administration of sorafenib. Secondary outcomes included the changes of laboratory data and other flow data revealed on DDU. RESULTS: PVA was significantly decreased after a 2-week administration (0.78 ± 0.23 vs. 0.64 ± 0.25, P = 0.023), while the portal venous flow velocity (PVV; cm/s) was not significantly changed (0.22 ± 0.06 vs. 0.24 ± 0.07, P = 0.17). Therefore, the congestion index (PVA/PVV), which reflects the pathophysiological hemodynamics of portal venous system, was significantly decreased (3.9 ± 1.7 vs. 3.0 ± 1.4, P = 0.042). CONCLUSIONS: We demonstrated the portal hemodynamic effect of sorafenib in patients with advanced HCC. Considering that this was a short-term study, because sorafenib could be a potential beneficial therapeutic agent for portal hypertension, it will be necessary to verify its clinical benefits for portal hypertension in future studies.

In a country such as Japan with the average age of patients with chronic hepatitis C treated with antivirals sometimes well above 60 years, the standard combination therapy is not well tolerated. In this randomized, prospective, controlled trial, we investigated the efficacy of 24-week peginterferon α monotherapy for easy-to-treat patients. A total of 132 patients chronically infected with hepatitis C virus (HCV) genotype 2 (n = 115) or low viral load HCV genotype 1 (<100 kIU/ml, n = 17) were treated with peginterferon α-2a (180 µg/week). Patients with a rapid virological response (RVR, HCV RNA negative or <500 IU/ml at week 4) were randomized for a total treatment duration of 24 (group A) or 48 (group B) weeks. Patients who did not show RVR (group C) were treated for 48 weeks. Sustained virological response (SVR) was assessed by qualitative reverse-transcription polymerase chain reaction. One hundred eight of 132 (82%) patients with RVR were randomized. SVR rates were 60% (group A), 79% (group B), and 27% (group C), respectively. Similar SVR rates were achieved in patients infected with HCV genotype 2 with low pretreatment viral load (<1000 kIU/ml) in group A (81%) and group B (79%) (P = 0.801), whereas in those with higher viral load (≥1000 kIU/ml), a lower SVR rate was identified in group A (26%) than in group B (67%) (P = 0.041). In conclusion, in patients infected with HCV genotype 2 and pretreatment viral load below 1000 kIU/ml who achieve RVR, 24-week treatment with peginterferon α-2a alone is clinically sufficient. Those who show no RVR or have higher baseline viral load, require alternative therapies.
