Sorafenib plus partial splenic embolism for treatment of hepatocellular carcinoma Barcelona stage C combined with hypersplenism: a case series.

BACKGROUND: Sorafenib is mainly used to treat patients with hepatocellular carcinoma (HCC) Barcelona Clinic Liver Cancer (BCLC) stage C, many of whom also have severe cirrhosis. However, hypersplenism and digestive tract hemorrhage are common complications of cirrhosis, which increase the risk and difficulty of treatment. METHODS: Nineteen patients with HCC BCLC stage C with hypersplenism were treated with sorafenib plus partial splenic embolism at Chongqing University Cancer Hospital, Chongqing, China, between January 2015 and June 2018. We analyzed the therapeutic effect and clinical safety of this treatment in these patients. RESULT: Hypersplenism was rectified in all patients. The incidence rates of hemorrhage and myelosuppression were 0%, and the mean survival time was 11.2 months. CONCLUSION: Sorafenib plus partial splenic embolism could relieve hypersplenism and prolong survival in patients with BCLC stage C HCC.

Use of Iodized Oil and Gelatin Sponge Embolization in Splenic Artery Coiling Reduces Bleeding from Laparoscopic Splenectomy for Cirrhotic Portal Hypertension Patients with Complicating Hypersplenic Splenomegaly: A Comparative Study.

OBJECTIVE: Laparoscopic splenectomy (LS) is relatively contraindicated in cirrhotic portal hypertension (CPH) patients with complicating hypersplenic splenomegaly (HS). This study aimed to evaluate the effectiveness and safety of incorporation of iodized oil and gelatin sponge embolization to conventional splenic artery embolization (cSAE) with coiling in CPH/HS patients undergoing LS. PATIENTS AND METHODS: Between April 2012 and March 2014, eligible CPH/HS patients (n = 56) were assigned to preoperative modified SAE (mSAE) with LS (mSAE+LS group, n = 16), cSAE with LS (cSAE+LS group, n = 20) or LS alone (LS group, n = 20). Main outcome measures included frequency of conversion to laparotomy, operative time, intraoperative bleeding, and transfusion. RESULTS: The three groups had similar baseline characteristics (all P > .05). mSAE and cSAE similarly decreased LS conversion frequency (mSAE+LS versus cSAE+LS versus LS, 0.0% versus 10.0% versus 30.0%, P = .030) and operative time (155 ± 23 minutes versus 170 ± 26 minutes versus 221 ± 42 minutes, P < .001) compared with LS alone. mSAE significantly reduced bleeding (178 ± 22 mL versus 250 ± 27 mL versus 328 ± 67 mL, P < .001) compared with cSAE and LS alone. The three groups had similar postoperative recovery times and surgical morbidities (all P > .05). CONCLUSIONS: In CPH/HS patients, preoperative SAE reduced LS conversion frequency and reduced operative time compared with LS alone, while mSAE further decreased volume of blood loss.

Electromagnetic thermoablation to treat thrombocytopenia in cirrhotic and hypersplenic rats.

BACKGROUND AND AIM: Thrombocytopenia due to hypersplenism is usually a serious condition in cirrhotic patients who have undergone invasive procedures. We designed a new treatment method using a high-frequency alternating electromagnetic force to treat the disease condition in a rat model. METHODS: Sprague-Dawley rats were given thioacetamide in drinking water and injected with methylcellulose intraperitoneally to create a cirrhotic hypersplenism model. Spleen volume was determined using the Carlson method. The Control Group consisted of 14 rats, 15 weeks old, that were used to determine the normal platelet count and normal spleen size. Experimental Group I, consisting of 15 rats, received electromagnetic thermoablation of their spleens, after which the spleen was returned to the abdomen. Group II consisted of 13 rats, receiving the same electromagnetic thermoablation as Group I, but the ablated portion was removed. Group III consisted of 14 rats receiving total splenectomies. RESULTS: Cirrhotic hypersplenism was confirmed during laparotomy and pathological examination. Spleen volume enlarged from 1513 +/- 375 mm(3) (Control Group) to 7943 +/- 2822 mm(3) (experimental groups). Platelet counts increased from 0.35 +/- 0.21 x 10(6)/mm(3) to 0.87 +/- 0.24 x 10(6)/mm(3) for Group I, from 0.52 +/- 0.23 x 10(6)/mm(3) to 1.10 +/- 0.20 x 10(6)/mm(3) for Group II, and from 0.47 +/- 0.23 x 10(6)/mm(3) to 1.18 +/- 0.26 x 10(6)/mm(3) for Group III. No rats died due to the treatment in any of the experimental groups. CONCLUSIONS: Our animal model performed successfully and our proposed electromagnetic thermotherapy effectively treated thrombocytopenia due to cirrhotic hypersplenism.

[Study on primary hepatocellular carcinoma associated with hypersplenism treated by partial splenic embolization combined with hepatic arterial chemoembolization].

BACKGROUND & OBJECTIVE: 70-90% of patients of primary hepatocellular carcinoma (PHC) are associated with liver cirrhosis, portal hypertension and hypersplenism. The treatment of PHC is usually hampered by low or slow recovery of blood cell counts. This study was to investigate the effect of partial splenic embolization (PSE) combined with transcatheter hepatic arterial chemoembolization (TACE) for the treatment of PHC with portal hypertension and hypersplenism. METHODS: Efficacy of 26 patients with PSE combined with TACE and 26 patients with single TACE was observed. RESULTS: Satisfactory effects were achieved in PSE combined with TACE group in terms of correction of blood cell counts compared with cases treated with TACE alone. CONCLUSION: PSE associated with TACE is safe and effective for the treatment of patients with PHC associated with liver cirrhosis, portal hypertension and hypersplenism.
