Purpose: To evaluate the effect of chronic liver disease (CLD) in a multivariate analysis of associated risk factors in patients with hepatocellular carcinoma (HCC) using transarterial chemoembolization (TACE). Materials and methods: A total of 145 patients with HCC (99 men, 46 women; mean age: 63 years ±8.1; age range: 46-84 years) underwent 598 TACE procedures. The presence of CLD, number and location of lesions, tumor size, Child-Pugh score, vascularity, portal involvement and alpha fetoprotein value were analyzed using the multivariate regression model. Cox regression was used for survival analysis. Results: The median survival time was 26.7 months, and 78.6% of all treated lesions showed tumor responses. The presence of CLD (OR 2.12, P=0.004), Child-Pugh score B (OR 2.24, P=0.002), alpha fetoprotein >100ng/dl (OR 1.18, P<0.001), multinodularity (≥3 lesions) (OR 4.41, P=0.003), lesion size >5cm (OR 4.12, P=0.002) and hypervascularity (OR 7.94, P=0.003) were significant effective factors for a local response when analyzed using a multivariate logistic model. Multivariate survival analysis using Cox's regression model during the median follow-up period of 25 months (range: 1-42 months) demonstrated a significant difference in survival rates (P values <0.05). No significant difference in responses was noted for males, locations of lesions and portal involvements statistically. Conclusion: The presence of chronic liver disease as well as associated risk factors including Child-Pugh score B, alpha fetoprotein 100ng/dl, multinodularity (≥3 lesions), lesion size >5cm and hypervascularity statistically led to a significant effect in tumor response in HCC patients treated with TACE. Patient gender, location of lesion and involvement of portal vein showed no significant difference in response.
Background & Aims: Thrombopoietin receptor agonists are a new class of compounds licenced for the treatment of immune thrombocytopenic purpura. They are currently being studied for patients with thrombopenia in advanced liver disease or under therapy for hepatitis C. There are indications that the risk for development of portal vein thrombosis in patients with advanced liver cirrhosis might be increased under therapy with thrombopoietin receptor agonists. We report a case of a patient with Child class B liver cirrhosis with concurrent immune thrombocytopenic purpura that developed portal vein thrombosis under therapy with the thrombopoietin receptor agonist romiplostim.
Methods: A 50-year-old woman with hepatitis C virus associated immune thrombocytopenic purpura and Child class B liver cirrhosis presented in our emergency with rapidly evolving hydropic decompensation and general malaise. For immune thrombocytopenic purpura, the patient was started on the thrombopoietin receptor agonist romiplostim nine months ago.
Results: During hospitalization, the platelet count was measured above 330,000/μl and partial portal vein thrombosis was diagnosed by imaging studies. The thrombotic event was assumed to be associated with the romiplostim treatment for immune thrombocytopenic purpura via excessive elevation of platelet count. After anticoagulation with heparin and cessation of romiplostim treatment, complete recanalisation of the portal vein was achieved.
Conclusions: We conclude that romiplostim should be used with precaution in patients with hepatitis C-associated immune thrombocytopenic purpura and advanced liver cirrhosis as the risk for thrombotic complications may increase significantly.
