Materials & methods This retrospective cohort study included patients who initiated lenvatinib monotherapy as first-line treatment for uHCC (n = 233). Clinical outcomes included provider-reported best response, progression-free survival (PFS) and overall survival (OS). PFS and OS were estimated using Kaplan-Meier methods. Results Most patients (67.8%) were male. A total of 44.6% had Child-Pugh A and 39.1% had Child-Pugh B. Dose reductions were reported in 9%. Median PFS and OS were not reached. At 6 and 12 months, landmark PFS were 85.1 and 64.9%, respectively; landmark OS were 91.8 and 72.6%, respectively. Conclusion These results affirm the clinical effectiveness of first-line lenvatinib monotherapy in uHCC. Percutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option. To report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review. MEDLINE databases were searched for case reports and series including children and iatrogenic catheter fragments or guidewires retrieved through percutaneous techniques. We also conducted a retrospective analysis of 14 cases from our institution over a 14-year period. A total of 27 studies were selected comprising 74 children, plus our 14 unpublished cases. Statistical analyses were performed using Microsoft Excel version 2016. Port catheter fragments and peripherally inserted central catheters (PICCs) were the most embolized foreign bodies and the pulmonary artery was the most common site of embolization in 44.1% of cases. Analysis of the retrieval technique demonstrated a preference for extraction through the femoral vein (81.7%) and using snare techniques (93.5%). The success rate of percutaneou
