Hepatocellular Carcinoma Surveillance Strategies: Major Guidelines and Screening Advances.

Background/objectives: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths globally, with prognosis and treatment outcomes that are significantly influenced by the stage at diagnosis. Early detection through regular surveillance is crucial for improving patient outcomes, especially in high-risk groups such as those with cirrhosis or chronic hepatitis B. Geographic variations in HCC risk factors, including viral hepatitis and non-alcoholic fatty liver disease (NAFLD), have led to the development of different international surveillance guidelines.

Role of Imaging in Diagnosis and Management of COVID-19: Evidence-Based Approaches.

Imaging has been demonstrated to play a crucial role in both the diagnosis and management of COVID-19. Depending on resources, pre-test probability, and risk factors for severe disease progression, real-time polymerase chain reaction (RT-PCR) testing may be followed by chest radiography (CXR) or chest computed tomography (CT) to further aid in diagnosis or excluding COVID-19 disease. SARS-CoV-2 has been shown not only to pathologically impact the pulmonary system, but also the cardiovascular, gastrointestinal, and neurological systems to name a few.

Trans-arterial embolization versus chemoembolization for neuroendocrine liver metastases: a propensity matched analysis.

Introduction: Locoregional therapies are a mainstay of treatment for patients with neuroendocrine liver metastases (NELM), yet the optimal transarterial approach remains undefined and recent studies have raised concern over the safety of transarterial chemoembolization (TACE).

Methods: Patients with NELM who underwent TACE or transarterial embolization (TAE) at a single institution between 2000-2022 were retrospectively reviewed. Propensity score matching (PSM) controlling for age, sex, bilateral disease, tumor size, lobar embolization, grade, and extrahepatic disease was utilized to compare short- and long-term outcomes.

Clinical outcomes of DEB-TACE in locally advanced hepatocellular carcinoma: A 5-year real world experience.

Purpose: To evaluate outcomes including safety and efficacy of drug-eluting bead trans-arterial chemo-embolization (DEB-TACE) in the treatment of locally advanced hepatocellular carcinoma (LA-HCC).

Materials And Methods: In this single-center, retrospective study, we evaluated 471 consecutive patients with LA-HCC who underwent DEB-TACE from 2015 to 2020. Efficacy of DEB-TACE was assessed based on the imaging response using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) and the biochemical response using alpha-fetoprotein (AFP) levels at 1-month follow-up.

Value of interventional radiology and their contributions to modern medical systems.

Interventional radiology (IR) is a unique specialty that incorporates a diverse set of skills ranging from imaging, procedures, consultation, and patient management. Understanding how IR generates value to the healthcare system is important to review from various perspectives. IR specialists need to understand how to meet demands from various stakeholders to expand their practice improving patient care.

Examining the Efficacy and Safety of Combined Locoregional Therapy and Immunotherapy in Treating Hepatocellular Carcinoma.

More than 800,000 people worldwide are diagnosed with HCC (hepatocellular carcinoma) each year, with approximately 700,000 deaths alone occurring in that same year. Treatment of HCC presents complex therapeutic challenges, particularly in intermediate and advanced stages. LRTs such as transarterial chemoembolization (TACE) and ablations have been the mainstay treatment for early to intermediate-stage HCC, and systemic therapies are used to treat intermediate-late-stage HCC.

Advances in Image-Guided Ablation Therapies for Solid Tumors.

Image-guided solid tumor ablation methods have significantly advanced in their capability to target primary and metastatic tumors. These techniques involve noninvasive or percutaneous insertion of applicators to induce thermal, electrochemical, or mechanical stress on malignant tissue to cause tissue destruction and apoptosis of the tumor margins. Ablation offers substantially lower risks compared to traditional methods.

Erosion of embolization coil into the renal collecting system: Retrograde fragmentation of stone and coil via thulium laser lithotripsy.

A 50-year-old female developed kidney stones on an eroded embolization coil 16 months after percutaneous nephrolithotomy (PCNL) related bleeding complications. Retrograde ureteroscopy and thulium laser lithotripsy was performed to fragment the exposed portion of the coil into clinically insignificant pieces. Thulium laser coil fragmentation remains a potential strategy to remove eroded coils and their associated kidney stones; however, recurrent stone formation on the coil stump may necessitate repeat intervention if this conservative approach is pursued over radical antegrade coil removal.

Transarterial Chemoembolization Treatment Paradigms for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) accounts for 90% of liver cancer cases worldwide and is currently the most quickly increasing cause of cancer-related deaths in the United States. The 5-year survival rate for primary liver cancer is estimated to be below 20%, and HCC mortality is expected to increase by 41% by 2040. Currently, surgical resection is the first-line approach to definitive treatment of early-stage HCC.

Patient-Derived Conditionally Reprogrammed Cells in Prostate Cancer Research.

Prostate cancer (PCa) remains a leading cause of mortality among American men, with metastatic and recurrent disease posing significant therapeutic challenges due to a limited comprehension of the underlying biological processes governing disease initiation, dormancy, and progression. The conventional use of PCa cell lines has proven inadequate in elucidating the intricate molecular mechanisms driving PCa carcinogenesis, hindering the development of effective treatments. To address this gap, patient-derived primary cell cultures have been developed and play a pivotal role in unraveling the pathophysiological intricacies unique to PCa in each individual, offering valuable insights for translational research.

Liver-Directed Locoregional Therapies for Neuroendocrine Liver Metastases: Recent Advances and Management.

Neuroendocrine tumors (NETs) are a heterogeneous class of cancers, predominately occurring in the gastroenteropancreatic system, which pose a growing health concern with a significant rise in incidence over the past four decades. Emerging from neuroendocrine cells, these tumors often elicit paraneoplastic syndromes such as carcinoid syndrome, which can manifest as a constellation of symptoms significantly impacting patients' quality of life. The prognosis of NETs is influenced by their tendency for metastasis, especially in cases involving the liver, where the estimated 5-year survival is between 20 and 40%.

Locoregional Therapies for Hepatobiliary Tumors: Contemporary Strategies and Novel Applications.

A large majority of primary hepatobiliary tumors are hepatocellular carcinomas (HCC), with the remainer being cholangiocarcinoma. While surgical resection remains the gold standard treatment for hepatobiliary tumors, relatively few patients are operative candidates, and systemic treatments have limited effectiveness. Locoregional therapies offer significant promise in the management of HCC.
