Bland embolization

F Pesapane, N Nezami, F Patella, J F Geschwind
Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems...

PURPOSE: Transarterial embolization is frequently used to treat local hepatocellular carcinoma (HCC). While various complications are known to occur following transarterial embolization, only one prior case of peritoneal spread of HCC occurring shortly after transarterial chemoembolization has been reported. We present five cases of peritoneal spread of HCC following transarterial embolization (including bland embolization, conventional transarterial chemoembolization (TACE), and doxorubicin-eluting beads TACE) and identify features common among those cases...

Percutaneous radiofrequency ablation (RFA) for the treatment of stage I renal cell carcinoma has recently gained significant attention as the now available long-term and controlled data demonstrate that RFA can result in disease-free and cancer-specific survival comparable with partial and/or radical nephrectomy. In the non-controlled single center trials, however, the rates of treatment failure vary. Operator experience and ablation technique may explain some of the different outcomes. In the controlled trials, a major limitation is the lack of adequate randomization...

Undifferentiated embryonal sarcomas of the liver are extremely rare cases in adults. We report the case of a 30-year-old male who presented with early satiety and abdominal pain due to a massive tumor originating from the left liver and occupying the entire epigastrium. The patient underwent bland embolization in an attempt to decrease the size of the tumor. He then underwent a formal left hepatectomy with resection of liver segments 2, 3, and 4. Extrahepatic inflow control of the portal vein and hepatic artery was performed prior to parenchymal transection...

Colorectal cancer is the third leading cause of cancer death in the United States. Although hepatic excision is the first-line treatment for colorectal liver metastasis (CRLM), few patients are candidates. Locoregional therapy (LRT) encompasses minimally invasive techniques practiced by interventional radiology. These include ablative treatments (radiofrequency ablation, microwave ablation, and cryosurgical ablation) and transcatheter intra-arterial therapy (hepatic arterial infusion chemotherapy, transarterial "bland" embolization, transarterial chemoembolization, and radioembolization with yttrium 90)...

RATIONALE AND OBJECTIVES: Intra-procedural measurement of hepatic perfusion following liver embolization continues to be a challenge. Blood volume imaging before and after interventional procedures would allow identifying the treatment end point or even allow predicting treatment outcome. Recent liver oncology studies showed the feasibility of parenchymal blood volume (PBV) imaging using an angiographic C-arm system. This study was done to evaluate the reproducibility of PBV measurements using cone beam computed tomography (CBCT) before and after embolization of the liver in a swine model...

BACKGROUND: Intra-arterial brachytherapy with yttrium-90 ((90)Y) resin microspheres (radioembolization) is a procedure to selectively deliver high-dose radiation to tumors. The purpose of this research was to compare the radioembolic effect of (90)Y-radioembolization versus the embolic effect of bland microspheres in the porcine kidney model. METHODS: In each of six pigs, ~25-33 % of the kidney volume was embolized with (90)Y resin microspheres and an equivalent number of bland microspheres in the contralateral kidney...

PURPOSE: We tested the hypothesis that establishing a dedicated interventional oncology (IO) clinical service line would increase clinic visits and procedural volumes at a single quaternary care academic medical center. METHODS: Two time periods were defined: July 2012 to June 2013 (pre-IO clinic) and July 2013 to June 2014 (first year of dedicated IO service). Staff was recruited, and clinic space was provided in the institution's comprehensive cancer center. Clinic visits and procedure numbers were documented using the institution's electronic medical record and billing forms...

A 64-year-old patient developed sudden hypoglycemia leading to unconsciousness. Hypoglycemic episodes recurred on several occasions but were not accompanied by unconsciousness. Magnetic resonance imaging revealed a liver tumor in the right lobe sized 20.0 × 14.6 × 19.0 cm. No other masses were detected. Right hemihepatectomy was indicated but could not be performed due to heavy bleeding near the tumor. Histological examination showed a relatively cellular tumor made of elongated bland cells. The mitotic index was fewer than 4 mitoses per 10 HPF...

(90)Y radioembolization refers to the selective, transcatheter, and intra-arterial injection of micrometer-sized particles loaded with the radioisotope yttrium-90 for the treatment of primary and metastatic hepatic malignancies. In the treatment of intermediate- and advanced-stage hepatocellular carcinoma, (90)Y radioembolization provides favorable outcomes with minimal side effects, offering an alternative treatment option to other transarterial therapies, such as bland embolization and chemoembolization. This review provides an overview of the use of (90)Y radioembolization in the treatment of hepatocellular carcinoma, including patient selection criteria, dosimetry, and clinical outcomes...

BACKGROUND: The unique situation of the liver with arterial and venous blood supply and the dependency of the tumor on the arterial blood flow make this organ an ideal target for intrahepatic catheter-based therapies. Main forms of treatment are classical bland embolization (TAE) cutting the blood flow to the tumors, chemoembolization (TACE) inducing high chemotherapy concentration in tumors, and radioembolization (TARE) without embolizing effect but very high local radiation. These different forms of therapies are used in different centers with different protocols...

PURPOSE: To review the safety of hepatic radioembolization (RE) in patients with high (≥ 10%) hepatopulmonary shunt fraction (HPSF) using various prophylactic techniques. MATERIALS AND METHODS: A review was conducted of 409 patients who underwent technetium 99m-labeled macroaggregated albumin scintigraphy before planned RE. Estimated pulmonary absorbed radiation doses based on scintigraphy and hepatic administered activity were calculated. Outcomes from dose reductions and adjunctive catheter-based prophylactic techniques used to reduce lung exposure were assessed...

BACKGROUND: Transarterial chemoembolization (TACE) is the most common procedure for the treatment of hepatocellular carcinoma (HCC). However, HCC is generally considered chemoresistant and data demonstrating the superiority of TACE over bland embolization (TAE) are lacking. MATERIALS AND METHODS: A nationwide, retrospective cohort study of HCC patients treated with first-line TACE or TAE within the Veterans Affairs health care system (2005-2012) was performed. The primary outcome was overall survival...

BACKGROUND: Surgery is the only curative treatment for gastroenteropancreatic neuroendocrine tumors (GEP-NETs), but the prediction of residual disease/recurrence is limited in the absence of optimal biomarkers. We examined whether a blood-based multianalyte neuroendocrine gene transcript assay (NETest) would define tumor cytoreduction and therapeutic efficacy. METHODS: The NETest is a polymerase chain reaction-based analysis of 51 genes. Disease activity is scaled 0-100%; minimal <14%, low 14-47%, and high >47%...
