Results of a Global Survey on the State of Interventional Radiology 2024.

Purpose: To understand the state of IR practice and education worldwide and identify factors impacting access to IR services.

Methods And Materials: A Society of Interventional Radiology (SIR) approved anonymous survey was created to gather demographics, regional IR practice and education characteristics, and challenges impacting local IR development. The survey was distributed to members of global IR societies and shared on social media from 6/2022 to 9/2023.

CT versus MR guidance for radiofrequency ablation in patients with colorectal liver metastases: a 10-year follow-up favors MR guidance.

Objectives: To compare the results of CT- vs MR-guided radiofrequency ablation (RFA) of liver metastases (LM) from colorectal cancer after 10 years of follow-up in an observational, retrospective, and multicentric study.

Methods: A total of 238 patients with 496 LM were treated with RFA either with CT (CT group) or magnetic resonance (MR group) guidance. Every ablated LM was assessed and followed up with diagnostic MRI.

Local Tumour Control Following Microwave Ablation: Protocol for the Prospective Observational CIEMAR Study.

Purpose: Microwave ablation (MWA) is a treatment modality for colorectal liver metastases (CRLM). While potentially curative, more information is needed on factors that contribute to long-term local tumour control. The prospective multicentre observational study CIRSE Emprint Microwave Ablation Registry aims to prospectively collect real-world technical data and clinical outcomes on patients treated with MWA in CRLM.

CIRSE Position Paper on Artificial Intelligence in Interventional Radiology.

Artificial intelligence (AI) has made tremendous advances in recent years and will presumably have a major impact in health care. These advancements are expected to affect different aspects of clinical medicine and lead to improvement of delivered care but also optimization of available resources. As a modern specialty that extensively relies on imaging, interventional radiology (IR) is primed to be on the forefront of this development.

Research in interventional oncology: How sound is the evidence base?

Introduction: Interventional oncology (IO) is an essential component of cancer care, which has gained substantial recognition in recent years. The aim of this review is to evaluate the level of evidence supporting IO and its inclusion in cancer treatment guidelines.

Methods: A literature search of the PubMed database was performed to identify publication numbers and types for IO treatments published between 2012 and 2022.

Standardizing lymphangiography and lymphatic interventions: a preclinical in vivo approach with detailed procedural steps.

Purpose: To present a preclinical in vivo approach for standardization and training of lymphangiography and lymphatic interventions using a pictorial review.

Materials And Methods: Different lipiodol- and gadolinium-based lymphangiography and lymphatic interventions were performed in twelve (12) landrace pigs with a mean bodyweight of 34 ± 2 kg using various imaging and guiding modalities, similar to the procedures used in humans. The techniques used were explicitly introduced and illustrated.

Safety, Feasibility and Technical Considerations from a Prospective, Observational Study-CIREL: Irinotecan-TACE for CRLM in 152 Patients.

CIREL, a prospective, Europe-wide, observational study aimed to assess the real-world feasibility and tolerability of irinotecan-based transarterial chemoembolization (LP-irinotecan TACE) for unresectable colorectal cancer liver metastases with regard to the treatment plan and adverse events (AEs). CIREL enrolled 152 eligible patients (≥18 years) with liver-only or dominant metastases treated with LP-irinotecan TACE following a multidisciplinary tumor board decision. Data were prospectively collected for baseline, the number of planned and performed sessions, and technical information and safety according to CTCAE 4.

Role of interventional oncology for treatment of liver metastases: evidence based best practice.

The presence of liver metastases is associated with a poor prognosis in many cancer diseases. Multiple studies during the last decades aimed to find out the best multimodal therapy to achieve an ideal, safe and highly effective treatment. In addition to established therapies such as systemic therapy, surgery and radiation therapy, interventional oncology with thermal ablation, transarterial chemoembolisation and radioembolisation, is becoming the fourth pillar of cancer therapies and is part of a personalised treatments' strategy.

Present Status of Thyroid Ablation in Europe: An International Survey among the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) Members.

Aim: To evaluate the effective spread of image-guided thermal ablation in thyroid gland and to characterize its current perceptions among European interventional radiologists.

Materials And Methods: A questionnaire with 29 multiple choice questions about thyroid ablation was sent as an E-blast to 4752 CIRSE members. Only those who completed the survey in all its parts were included in the study.

[International comparison of radiological aspects of the new German S3 guideline on hepatocellular carcinoma and intrahepatic cholangiocarcinoma].

The updated German S3 guideline "Diagnostics and therapy of hepatocellular carcinoma and biliary carcinomas" covers two tumor entities. The original guideline published in 2013 focusing only on the diagnosis and therapy of hepatocellular carcinoma (HCC) has been expanded to include intrahepatic cholangiocarcinoma. These guidelines were developed within the framework of the guideline program on oncology of the Scientific Medical Society e.

[Transarterial radioembolization of hepatocellular carcinoma and intrahepatic cholangiocarcinoma].

Since the first version of the S3 guideline for the diagnosis and treatment of hepatocellular carcinoma (HCC) in 2013, a large number of studies have consolidated the data on transarterial radioembolization (TARE) and created a broad evidence base. As a result, TARE was incorporated into the current 2021 S3 guideline with a number of specific recommendations, whereas it was previously only offered under study conditions. TARE is now offered with the other minimally invasive procedures for bridging and downstaging before liver transplantation, but also as an alternative to transarterial chemotherapy (TACE) in intermediate HCC and in locally limited intrahepatic cholangiocarcinoma in second-line therapy for selected patients-albeit with different levels of evidence.

Consensus Guidelines for the Definition of Time-to-Event End Points in Image-guided Tumor Ablation: Results of the SIO and DATECAN Initiative.

There is currently no consensus regarding preferred clinical outcome measures following image-guided tumor ablation or clear definitions of oncologic end points. This consensus document proposes standardized definitions for a broad range of oncologic outcome measures with recommendations on how to uniformly document, analyze, and report outcomes. The initiative was coordinated by the Society of Interventional Oncology in collaboration with the Definition for the Assessment of Time-to-Event End Points in Cancer Trials, or DATECAN, group.
