The purpose of this study was to compare characteristics and outcomes of patients with breast cancer with liver metastasis who had and had not undergone radioembolization. Medical records of patients with breast cancer with liver metastases (4,332 patients who had not undergone radioembolization and 166 patients who had) seen between January 1, 2009, and October 31, 2021, were assessed. Propensity score matching was performed.

Role of Interventional Radiology in Managing Primary and Metastatic Breast Cancer.

Percutaneous image-guided locoregional therapies are emerging in the treatment of primary and metastatic breast cancer. Cryoablation has emerged as the dominant ablative approach as an alternative to surgery for primary breast cancer in patients who do not wish to have surgery or are poor surgical candidates. Cryoablation is well tolerated and provides excellent local control and cosmesis.

Tissue Ablation: Applications and Perspectives.

Tissue ablation techniques have emerged as a critical component of modern medical practice and biomedical research, offering versatile solutions for treating various diseases and disorders. Percutaneous ablation is minimally invasive and offers numerous advantages over traditional surgery, such as shorter recovery times, reduced hospital stays, and decreased healthcare costs. Intra-procedural imaging during ablation also allows precise visualization of the treated tissue while minimizing injury to the surrounding normal tissues, reducing the risk of complications.

New Frontiers in the Role of Locoregional Therapies in Breast Cancer: Proceedings from the Society of Interventional Radiology Foundation Research Consensus Panel.

Emerging evidence regarding the effectiveness of locoregional therapies (LRTs) for breast cancer has prompted investigation of the potential role of interventional radiology (IR) in the care continuum of patients with breast cancer. The Society of Interventional Radiology Foundation invited 7 key opinion leaders to develop research priorities to delineate the role of LRTs in both primary and metastatic breast cancer. The objectives of the research consensus panel were to identify knowledge gaps and opportunities pertaining to the treatment of primary and metastatic breast cancer, establish priorities for future breast cancer LRT clinical trials, and highlight lead technologies that will improve breast cancer outcomes either alone or in combination with other therapies.

Transarterial Embolization-Assisted Necrosis of a Facial Tumor.

The treatment and prognosis of non-operable high-risk head and neck squamous cell carcinoma (SCC) are poor. There is no definitive model for therapy in these cases to date, but strategies that have been utilized include radiation therapy (RT) with or without chemotherapy. Here, we report the effectiveness of arterial embolization with subsequent chemoradiation with cisplatin in a case of advanced oropharyngeal SCC.

Predictors of Major Hemorrhage After Spleen Core Biopsy in Cancer Patients.

In this retrospective study, 232 spleen biopsies from 218 patients with cancer were assessed. Biopsies resulting in hemorrhage requiring hospitalization, transfusion, or other interventions were compared with those that did not. The maximization of the Youden index helped determine the optimal systolic blood pressure (SBP) and platelet count thresholds.

Prospective Evaluation of Immune Activation Associated with Response to Radioembolization Assessed with PET/CT in Women with Breast Cancer Liver Metastasis.

Background The impact of transarterial radioembolization (TARE) of breast cancer liver metastasis (BCLM) on antitumor immunity is unknown, which hinders the optimal selection of candidates for TARE. Purpose To determine whether response to TARE at PET/CT in participants with BCLM is associated with specific immune markers (cytokines and immune cell populations). Materials and Methods This prospective pilot study enrolled 23 women with BCLM who planned to undergo TARE (June 2018 to February 2020).

Optimizing Y Particle Density Improves Outcomes After Radioembolization.

Purpose: To determine how particle density affects dose distribution and outcomes after lobar radioembolization.

Methods: Matched pairs of patients, treated with glass versus resin microspheres, were selected by propensity score matching (114 patients), in this single-institution retrospective study. For each patient, tumor and liver particle density (particles/cm) and dose (Gy) were determined.

Internet Search Trends Relevant to Interventional Oncology: A Google Trends Study (2004-2020).

Interventional Radiology (IR) procedures addressing cancer have been grouped in the subspecialty of interventional oncology and represent an important component of modern multidisciplinary cancer care. This study pinpoints temporal and geographical trends of public online searches for terms related to the field, as well as IR-related cancer therapies. Google Trends data were analyzed for long-term (2004-2020) trends in the United States and worldwide.

Relationship of radiation dose to efficacy of radioembolization of liver metastasis from breast cancer.

Purpose: To determine the relationship of tumoral and nontumoral radiation dose to response and toxicity after transarterial radioembolization (TARE) of breast cancer liver metastasis.

Methods: This retrospective study evaluated all patients with breast cancer liver metastases treated with TARE (2/2011-6/2019). Extent of disease was measured as unilobar or bilobar on baseline PET/CT prior to TARE.

Hepatic Metastasis from Breast Cancer.

Breast cancer is the most common cancer in women and breast cancer liver metastasis may be associated with poor outcomes. Emerging locoregional therapies can be given in outpatient settings or with short hospital stays, to provide local control, support quality of life, preserve liver function, and potentially prolong survival. This review discusses retrospective studies suggesting potential benefits of locoregional treatment of breast cancer liver metastasis.

Gender Disparity in Industry Relationships With Academic Interventional Radiology Physicians.

Industry relationships drive technologic innovation in interventional radiology and offer opportunities for professional growth. Women are underrepresented in interventional radiology despite the growing recognition of the importance of diversity. This study characterized gender disparities in financial relationships between industry and academic interventional radiologists.

Procedural complications of inferior vena cava filter retrieval, an illustrated review.

Annually, approximately 65,000 inferior vena cava (IVC) filters are placed in the United States (Ahmed et al., J Am Coll Radiol 15:1553-1557, 2018). Approximately 35% of filters are eventually retrieved (Angel et al.

Cryoablation of a Symptomatic Chest Wall Desmoid Tumor Underneath a Silicone Breast Implant.

Desmoid tumors are locally aggressive tumors that have a high rate of reoccurrence, even after resection. Percutaneous cryoablation is an effective alternative treatment with less associated risk. A patient in the fifth decade of life with a history of ductal carcinoma-in-situ, status post bilateral mastectomy and silicone implant placement, presented with a palpable mass in the left breast, core biopsy proven to be a desmoid tumor underneath the implant.

Comparison of Radiographic Approaches to Assess Treatment Response in Pituitary Adenomas: Is RECIST or RANO Good Enough?

Context: Pituitary adenomas (PA) are often irregularly shaped, particularly posttreatment. There are no standardized radiographic criteria for assessing treatment response, substantially complicating interpretation of prospective outcome data. Existing imaging frameworks for intracranial tumors assume perfectly spherical targets and may be suboptimal.

Given recent specialty attention to workforce diversity, we aimed to characterize potential gender differences in the practice patterns of interventional radiologists (IRs). Using Medicare claims data, we identified IRs on the basis of the distribution of their billed clinical work effort and descriptively characterized practice patterns by gender. Women represented 8.

Advances in Biomaterials and Technologies for Vascular Embolization.

Minimally invasive transcatheter embolization is a common nonsurgical procedure in interventional radiology used for the deliberate occlusion of blood vessels for the treatment of diseased or injured vasculature. A wide variety of embolic agents including metallic coils, calibrated microspheres, and liquids are available for clinical practice. Additionally, advances in biomaterials, such as shape-memory foams, biodegradable polymers, and in situ gelling solutions have led to the development of novel preclinical embolic agents.
