Acquired amegakaryocytic thrombocytopenic purpura induced by percutaneous ethanol injection during treatment of hepatocellular carcinoma: A case report.

Percutaneous ethanol injection is an important localized treatment method for patients presenting with hepatocellular carcinoma (HCC). Among the advantages of percutaneous ethanol injection are its minimal invasiveness, simplicity, low cost and low risk of complications. However, the increasing popularity of percutaneous ethanol injection has resulted in serious adverse effects attributed to individual variations. The present study describes the case of a patient who exhibited acquired amegakaryocytic thrombocytopenic purpura, caused by percutaneous ethanol injection treatment for HCC. This complication was promptly identified, and platelet transfusion and injection of recombinant human interleukin-11 resulted in a rapid recovery of the patient's platelet count. Attention should be given to this rare complication in patients administered percutaneous ethanol injection treatment for HCC.

Enhanced therapeutic efficacy of combined use of sorafenib and transcatheter arterial chemoembolization for treatment of advanced hepatocellular carcinoma.

OBJECTIVE: Clinical trials suggest that combining transcatheter arterial chemoembolization with sorafenib in patients with advanced hepatocellular carcinoma shows a superior safety and tolerability profile. Our study aimed to retrospectively analyze the utility and prognostic factors of this combined therapy in these patients. METHODS: Patients with advanced hepatocellular carcinoma, treated by transcatheter arterial chemoembolization and sorafenib subsequently, between February 2010 and September 2012 in our hospital, were retrospectively analyzed. After sorafenib treatment for 12 weeks, abdominal enhanced computed tomography or magnetic resonance imaging was used to evaluate short-term outcomes and clinical benefit rate. Overall survival and adverse events were recorded during follow-up. Univariate and multivariate analyses were used to identify relationships between baseline characteristics and overall survival. RESULTS: Fifty-one advanced hepatocellular carcinoma patients were included. Common adverse events for sorafenib were hand-foot skin reaction, alopecia, diarrhea, anorexia and fatigue. The clinical benefit rate was 64% and the median survival time was 7.5 months. Median survival of patients with and without portal vein tumor thrombi was 6.0 months and 10.3 months (P < 0.001), respectively. Median survival of patients with cholinesterase ≥5000 U/l and < 5000 U/l was 10.6 months and 6.1 months (P < 0.001), respectively. Multivariate analysis identified the presence of portal vein tumor thrombi and low cholinesterase level as independent negative predictors of survival. CONCLUSIONS: Combining sorafenib and transcatheter arterial chemoembolization was safe and effective for advanced hepatocellular carcinoma patients with extrahepatic spread but without portal vein tumor thrombi. Portal vein tumor thrombi and cholinesterase level are independent predictors of prognosis following this combined therapy.
