Purpose: Metastatic breast cancer (MBC) is usually incurable; treatment aims to maximize patients' function and quality of life (QOL). Eribulin is a standard treatment in patients with MBC pretreated with anthracycline and taxane; however, the best administration schedule is unknown.

Methods: In this prospective phase II trial of patients with luminal MBC, we administered biweekly eribulin to patients who completed a three-cycle induction treatment.

Temporal Trends in Antithrombotic Therapy for Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention From 2014 to 2022 in Japan.

Recent revisions of clinical guidelines by the Japanese Circulation Society, American Heart Association/American College of Cardiology, and European Society of Cardiology updated the management of antithrombotic strategies for patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). However, the extent to which these guidelines have been implemented in real-world daily clinical practice is unclear. We conducted surveys on the status of antithrombotic therapy for patients with AF undergoing PCI every 2 years from 2014 to 2022 in 14 cardiovascular centers in Japan.

Necessity for surveillance for hepatocellualr carcinoma in older patients with chronic hepatitis C who achieved sustained virological response.

Background And Aim: Hepatocellular carcinoma (HCC) surveillance in low-risk patients (annual incidence <1.5%) is not recommended per the American Association for the Study of Liver Diseases guidelines. Because patients with chronic hepatitis C with non-advanced fibrosis who have achieved sustained virological response (SVR) have a low risk of HCC, HCC surveillance is not recommended for them.

Simple new clinical score to predict hepatocellular carcinoma after sustained viral response with direct-acting antivirals.

The time point of the most precise predictor of hepatocellular carcinoma (HCC) development after viral eradication with direct-acting antiviral (DAA) therapy is unclear. In this study we developed a scoring system that can accurately predict the occurrence of HCC using data from the optimal time point. A total of 1683 chronic hepatitis C patients without HCC who achieved sustained virological response (SVR) with DAA therapy were split into a training set (999 patients) and a validation set (684 patients).

Clinical outcome of endovascular therapy using a VIABAHN VBX-covered stent for complex aortoiliac artery disease: the AVOCADO II study.

Clinical trials have demonstrated the efficacy of a balloon-expandable covered stent (CS) for aortoiliac occlusive disease (AIOD). However, the real-world clinical outcomes and the underlying factors remain unclear. We assessed the clinical outcomes and factors associated with primary patency after implantation of a balloon-expandable CS for patients with complex AIOD.

Bypass Surgery Provides Better Outcomes Compared with Endovascular Therapy in Patients with Chronic Limb-Threatening Ischemia Classified as Indeterminate Category According to the Global Vascular Guidelines.

Background: The present study aimed to determine the preferred initial revascularization procedure between bypass surgery and endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI) categorized as indeterminate according to the Global Vascular Guidelines (GVG).

Methods: We retrospectively analyzed the multicenter data of patients who underwent infrainguinal revascularization for CLTI categorized as indeterminate according to the GVG between 2015 and 2020. The end point was the composite of relief from rest pain, wound healing, major amputation, reintervention, or death.

Clinical outcomes of chronic limb-threatening ischemia due to inflammatory nonatherosclerotic versus atherosclerotic etiologies undergoing revascularization.

Background: The scope of clinical guidelines for the management of chronic limb-threatening ischemia (CLTI) is limited to atherosclerotic disease of the lower-extremity arteries. This study aimed to reveal the clinical features and prognoses of CLTI due to inflammatory nonatherosclerotic etiologies undergoing revascularization.

Methods: DECOPON (DatabasE of ChrOnic limb-threatening ischemia Presenting ischemic ulcer and gangrene due to nON-atherosclerotic disease) is a multicenter retrospective study that evaluated 465 limbs of 414 patients with CLTI undergoing revascularization for ischemic tissue loss with inflammatory nonatherosclerotic etiologies between 2010 and 2020.

Survival impact of pancreatic resection for metastases in the pancreas: A retrospective multi-center study.

Background: Pancreatic metastases from other primary malignancies are rare. There is no clear evidence for a treatment strategy for this condition. The purpose of this study was to assess the clinical outcomes, including prognostic factors for pancreatic resection of metastatic tumors in the pancreas, through a retrospective review.

Stent Implantation and Thromboendarterectomy for the Common Femoral Artery in Real-World Practice.

Purpose: To compare the outcomes of thromboendarterectomy (TEA) and endovascular therapy (EVT) with stenting for patients with atherosclerotic common femoral artery (CFA) occlusive disease.

Materials And Methods: From a retrospective registry of 1193 consecutive patients with CFA treatment performed between 2018 and 2020 at 66 institutions in Japan, we identified patients who underwent TEA (n=432) or stent implantation (n=157). The primary outcome measures were the 1-year primary patency of TEA versus stenting with propensity score matching.

A Case of General Anaesthesia Using an I-gel Airway for MRI of an Adult Patient With Athetoid Cerebral Palsy.

Patients with athetoid cerebral palsy may develop cervical myelopathy owing to repetitive involuntary motion. In these patients, MRI evaluation is required; involuntary motion is problematic, and general anaesthesia and immobilisation may be necessary. However, MRI studies requiring muscle relaxation and general anesthesia in adults are rare.
