Purpose: This study aimed to assess the safety and efficacy of endovascular treatment of unruptured pancreatic arcade aneurysms in a single-center series.

Materials And Methods: The electronic medical records of patients who underwent endovascular treatment for unruptured pancreatic arcade aneurysms between 2011 and 2022 at our tertiary center were retrospectively reviewed. The presence of celiac artery stenosis/occlusion; aneurysm number, location, and size; endovascular technique; procedure-related complication incidence; and clinical outcomes were assessed.

Purpose: To retrospectively investigate the safety and effectiveness of percutaneous radiofrequency (RF) ablation by analyzing results in patients with lung neoplasm accompanied by interstitial lung disease (ILD) on computed tomography (CT) in a multicenter study.

Materials And Methods: Patients with lung neoplasm accompanied by ILD who underwent RF ablation between April 2002 and October 2017 at 7 institutions were investigated. Technical success rate and local tumor progression (LTP) of ablated tumors were evaluated.

The enhancement of T cell and NK cell function is an immunotherapeutic strategy for combating cancer. Antibodies that block inhibitory receptors, such as PD-1 and CTLA4, augment T cell function and have been successful in curing patients with some types of cancer. As an alternative approach to targeting specific inhibitory receptors by antibodies, small molecule drugs that inhibit negative regulators of T cell activation have been sought.
