[The clinical therapeutic effects of arsenic trioxide combined with transcatheter arterial chemoembolization in treating primary liver cancer with pulmonary metastases].

OBJECTIVE: To observe the therapeutic effects of arsenic trioxide combined with transcatheter arterial chemoembolization on treatment of primary liver cancer with pulmonary metastases. METHODS: Sixty patients were randomly divided into two groups: group A (treatment group, n = 30) and group B (control group, n = 30). Group A was received periodic transcatheter arterial chemoembolization (TACE) and 10 mg arsenic trioxide by intravenous infusion for 5 hours per day, 3 days after TACE. Each cycle consisted of 14 days' administration, and repeated after 2 weeks. Each patient was received 3-4 successive cycles. Group B was received periodic TACE alone. OBJECTIVE: efficiency, benefit rate, quality of life and the correlates with metastatic tumor size and number in the both groups were recorded. RESULTS: The objective efficiency was 26.7% (8/30), and the benefit rate was 60.0% (18/30) in group A, while they were 0 and 16.7% (5/30) in group B with significant statistics differences (χ(2) = 7.067, P = 0.008; χ(2) = 11.915, P = 0.001). The quality of life was improved in 4 patients and stable in 18 of group A, while no patient was improved and 13 were stable in group B (χ(2) = 9.669, P = 0.008). There was a significantly positive correlation between the tumor burden and therapeutic effect (Kendall r = -0.765, P < 0.001; Spearman r = -0.821, P < 0.001). CONCLUSION: Arsenic trioxide combined TACE is an effective treatment method in treating primary liver cancer with pulmonary metastases.

Sorafenib improves lipiodol deposition in transarterial chemoembolization of Chinese patients with hepatocellular carcinoma: a long-term, retrospective study.

OBJECTIVE: Though synergy of sorafenib and transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) is well discussed in previous reports, association of lipiodol retention by sorafenib addition to TACE with the survival outcomes remain elusive. Therefore, we studied the impact of sorafenib addition to TACE on survival outcomes mediated by lipiodol retention. MATERIALS AND METHODS: This is a long-term, retrospective, single-center study using medical records of patients diagnosed with HCC at the Department of Interventional Radiology of Zhengzhou University Affiliated Cancer Hospital (China) between April 2004 and March 2012. RESULTS: Lipiodol deposition of > 50% was significantly increased in TACE + sorafenib group (70.87%) compared to TACE alone group (45.11%) (P = 0.0001). Significant increase in lipiodol deposition with sorafenib treatment was observed compared to TACE alone group (OR = 0.449, P = 0.041). The median overall survival in TACE + sorafenib and TACE alone groups were 38 months [95% CI = 9.772-56.228] and 31 months [95% CI = 21.855-40.145] respectively. Also, the hazard of death was comparatively greater in TACE alone group than TACE + sorafenib group [HR = 1.071]. Response rate to the therapy significantly increased after sorafenib administration to TACE patients, [compared to TACE alone treatment [69/103 (66.99%)] vs 55/133 (41.35%)], P = 0.0001. CONCLUSIONS: Lipiodol deposition is significantly increased upon sorafenib addition after TACE. However, there was no significant impact of lipiodol deposition on the survival benefits exerted by the synergistic combination and hence, future prospective trails are warranted to validate the findings of this study.

Influence of lactulose on interventional therapy for HCC patients with hepatocirrhosis and hypersplenism.

OBJECTIVE: To investigate the influence of lactulose on immunity of hepatocellular carcinoma (HCC) patients with hepatocirrhosis and hypersplenism after double-interventional therapies. METHODS: A total of 40 HCC patients with hepatocirrhosis and hypersplenism, hospitalized during January 2013 to June 2014, were enrolled and randomized into control group and observation group. Both groups received partial splenic embolization combined with transcatheter arterial chemoembolization. Besides, observation group orally took lactulose 30 mL/d. Four days before interventional therapies and at days 1, 3, 7 and 14 after therapies, fasting venous blood was collected to detect white blood cell count, red blood cell count (RBC), and platelet count (PLT). Four days before therapies and at days 7 and 14 after therapies, the levels of alanine aminotransferase, aspartate transaminase, total bilirubin, malondialdehyde, super-oxide dismutase (SOD), IFN-γ, and IL-4 as well as the distribution of T cell subsets in peripheral blood were tested. Complications were observed after interventional therapies. RESULTS: Before interventional therapies the levels of white blood cell count, PLT and RBC in both groups showed no difference, while after interventional therapies the levels of PLT and RBC in both groups showed an increasing tendency (P < 0.05). At day 14 after interventional therapies, the level of blood cell as well as that of SOD, IFN-γ and IL-4 in serum were significantly higher than that before therapies; meanwhile, the levels of alanine aminotransferase and total bilirubin of observation group after therapies were significantly lower than before and control group (P < 0.05), the levels of CD4(+)/CD8(+), SOD and IFN-γ were all higher than before and control group (P < 0.05). CONCLUSIONS: Oral administration of lactulose could adjust the imbalance of oxidation system/antioxidant system in HCC patients with hepatocirrhosis and hypersplenism after interventional therapies, and improve the antitumor immunity and prognosis.

Tumor vascularity and lipiodol deposition as early radiological markers for predicting risk of disease progression in patients with unresectable hepatocellular carcinoma after transarterial chemoembolization.

This study evaluated the factors impacting overall survival (OS) and time to progression (TTP) in patients with unresectable hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE). HCC patients were grouped based on tumor vascularity and lipidiol deposition after TACE. Tumor vascularity was classified based on contrast enhancement on arterial phase baseline CT scans. Lipiodol deposition was evaluated using CT scans. The progression-free rate was significantly higher in patients with good blood supply + good lipiodol deposition compared to those with good blood supply + poor lipiodol deposition. In patients with poor lipidiol deposition, risk of death was significantly positively correlated with stage, and negatively correlated with number of TACE procedures and degree of lipidiol deposition after the first TACE. Risk of disease progression in these patients was positively correlated with tumor size, and negatively correlated with number of TACE procedures and degree of lipidiol deposition after the first TACE. Our data showed that tumor vascularity and lipiodol deposition can be used as early radiological markers to identify patients who do not respond to TACE, and who can be considered earlier for alternative combination treatment strategies. Our data also indicated that poor lipiodol retention may predict a poor TTP and OS despite the blood supply status.
