Advancements in lung cancer: a comprehensive perspective on diagnosis, staging, therapy and follow-up from the SAKK Working Group on Imaging in Diagnosis and Therapy Monitoring.

In 2015, around 4400 individuals received a diagnosis of lung cancer, and Switzerland recorded approximately 3200 deaths related to lung cancer. Advances in detection, such as lung cancer screening and improved treatments, have led to increased identification of early-stage lung cancer and higher chances of long-term survival. This progress has introduced new considerations in imaging, emphasising non-invasive diagnosis and characterisation techniques like radiomics.

Safety and efficacy of percutaneous arterial port Implantation for Hepatic Arterial Infusion Chemotherapy.

Objectives: Approximately 40% of patients with colorectal cancer will develop liver metastases. Hepatic arterial infusion chemotherapy (HAIC) represents a valuable treatment option, with curative, palliative, or adjuvant intent. The aim of our study was to describe technical considerations, safety, and oncological outcomes of patients receiving HAIC.

The effect of preoperative embolization on giant cell tumors of the bone localized in the iliosacral region of the pelvis.

Introduction: Giant cell tumors of the bone (GCTB) are aggressive neoplasms, with rare occurrences in the posterior pelvis and sacral area. Surgical challenges in this region include the inability to apply a tourniquet and limited cementation post-curettage due to proximity to neurovascular structures, leading to potential complications. This case-control study explores the impact of preoperative embolization on GCTB located in the iliosacral region.

Plantar vein thrombosis: 17-year longitudinal study of consecutive patients from a Swiss academic center.

Background: Plantar vein thrombosis (PVT) is a rare condition. Less than 50 cases have been described in the literature. Evidence from interventional and observational studies is sparse or lacking.

Multi-Energy Low-Kiloelectron Volt versus Single-Energy Low-Kilovolt Images for Endoleak Detection at CT Angiography of the Aorta.

Purpose To compare image quality, diagnostic performance, and conspicuity between single-energy and multi-energy images for endoleak detection at CT angiography (CTA) after endovascular aortic repair (EVAR). Materials and Methods In this single-center prospective randomized controlled trial, individuals undergoing CTA after EVAR between August 2020 and May 2022 were allocated to imaging using either low-kilovolt single-energy images (SEI; 80 kV, group A) or low-kiloelectron volt virtual monoenergetic images (VMI) at 40 and 50 keV from multi-energy CT (80/Sn150 kV, group B). Scan protocols were dose matched (volume CT dose index: mean, 4.

Long-term patency of arteriovenous fistulas for hemodialysis: A decade's experience in a transplant unit.

Background: The heterogeneous quality of studies on arteriovenous fistulas outcome, with variable clinical settings and large variations in definitions of patency and failure rates, leads to frequent misinterpretations and overestimation of arteriovenous fistula patency. Hence, this study aimed to provide realistic and clinically relevant long-term arteriovenous fistula outcomes.

Methods: We retrospectively analyzed all autologous arteriovenous fistulas at our center over a 10-year period (2012-2022).

Peritransplant Varicosis After Simultaneous Pancreas and Kidney Transplantation Is an Uncommon Cause of Late-Onset and Recurrent Gastrointestinal Bleeding.

Ectopic peritransplant varicosis represents an uncommon cause of late-onset gastrointestinal (GI) bleeding after simultaneous pancreas and kidney transplantation (SPK). We report on a 53-year-old female patient who suffered from recurrent upper GI bleeding seven years after SPK with persistent graft function. Upper endoscopy revealed perianastomotic angiodysplasias, treated by clipping and Argon-Plasma-Coagulation.

Thermal ablation of the most challenging cases of liver metastases.

Patient selection for image-guided thermal ablation of liver metastases has to be taken in a multidisciplinary tumor board given the extreme complexity of cancer metastatic disease, and the numerous treatment options offered to oligometastatic patient today.The role of image-guided thermal ablation increases over years in the treatment of liver metastases. In order to fulfill the expected outcomes which are to have a local control rate equivalent to surgery, interventional oncologist have to take every measure that will help when treating most challenging metastases including image guidance, anesthesia, respiration monitoring, ablation technique, confirmation software that can favor positive outcomes, and in some way to render challenging metastases easy to treat.

Patients were subdivided into training cohort (n = 100) and test cohort (n = 50).

Percutaneous Fixation of Impending Fracture of the Hip.

According to the literature, prophylactic consolidation of proximal femur lytic metastasis the is recommended when the Mirels' score is above 8. Osteoplasty (cementoplasty of proximal femur) alone provides inadequate consolidation. Various mini-invasive technics, augmented osteoplasties, have been proposed for better long-term consolidation.

Tapping basement membrane motifs: Oral junctional epithelium for surface-mediated soft tissue attachment to prevent failure of percutaneous devices.

Teeth, long-lasting percutaneous organs, feature soft tissue attachment through adhesive structures, hemidesmosomes, in the junctional epithelium basement membrane adjacent to teeth. This soft tissue attachment prevents bacterial infection of the tooth despite the rich - and harsh - microbial composition of the oral cavity. Conversely, millions of percutaneous devices (catheters, dental, and orthopedic implants) fail from infection yearly.

The PEARL Approach for CT-guided Lung Biopsy: Assessment of Complication Rate.

Background Percutaneous CT-guided biopsy of lung nodules is an established method with high diagnostic accuracy but a high rate of pneumothorax and chest tube insertion compared with endobronchial methods. Purpose To investigate the effect of a protocol combining patient positioning biopsy-side down, needle removal during expiration, autologous blood patch sealing, rapid rollover, and pleural patching (PEARL) on complication rate after percutaneous CT-guided lung biopsy, especially chest tube insertion. Materials and Methods In a secondary analysis of both prospectively and retrospectively acquired data from December 2019 to November 2020, consecutive participants underwent biopsy with use of the PEARL protocol (prospective data) and were compared with patients who underwent biopsy at the same tertiary cancer center according to the standard method without any additional techniques (controls, retrospective data).
