Non-invasive removal of a misplaced and knotted guidewire during ultrasound-guided central venous catheter insertion in a hybrid operating room: a case report.

Background: The standard of care for placement of a central venous catheter (CVC) includes a real-time ultrasound (US)-guided technique. We describe a rare case in which the guidewire penetrated the posterior wall of the vessel, forming a knot, which precluded simple removal. This occurred despite the procedure being performed under real-time US guidance.

[Survey Report on Assistant Work of Radiological Technologist During Angiography and Intervention Radiology Procedure].

Purpose: Investigating the status and challenges associated with radiological technologists acting as assistants during angiography and interventional radiology (IVR) through task shift/share.

Methods: The survey period was from August 1, 2023 to September 30, 2023. A 10-item questionnaire survey was conducted nationwide, targeting 676 hospitals equipped with angiography facilities.

Optimal Therapy for Postoperative Recurrence: Does Salvage Radiation Work for Locoregional Recurrence?

Background/aim: Survival outcomes in patients with successfully resected non-small-cell lung cancer (NSCLC) are not well understood. Furthermore, the best treatment strategy for postoperative locoregional recurrence has not been established.

Patients And Methods: Patients who underwent R0 resection of NSCLC between 2013 and 2022 were retrospectively reviewed.

Modified FOLFOXIRI plus cetuximab versus bevacizumab in RAS wild-type metastatic colorectal cancer: a randomized phase II DEEPER trial.

The clinical significance of FOLFOXIRI (5-FU, leucovorin, oxaliplatin, and irinotecan) plus anti-EGFR monoclonal antibody using cetuximab for metastatic colorectal cancer (mCRC) remains controversial. We report results from a randomized phase 2 DEEPER trial (UMIN000018217, jRCTs061180022) to test the superiority of modified (m)-FOLFOXIRI plus weekly cetuximab over bevacizumab in patients with RAS wild-type (wt) mCRC. Primary endpoint was depth of response (DpR).

Effective Preparation of FFPE Tissue Samples for Preserving Appropriate Nucleic Acid Quality for Genomic Analysis in Thyroid Carcinoma.

Formalin-fixed paraffin-embedded (FFPE) tissue samples are important for genomic analysis of thyroid carcinomas, particularly for various molecularly targeted therapies. Therefore, this study developed and validated a technique for preparing FFPE tissue samples that preserves nucleic acid quality, which is fundamental for precise genomic analysis, more effectively than conventional methods. We analyzed surgically resected thyroid gland tumors, lymph node metastases, and separately fixed tumor samples to optimize formalin fixation and assess the influence of specimen type and preparation methods on nucleic acid quality.

Prognostic factors in patients with pathological T3N0M0 gastric cancer: A multi-institutional, retrospective study (YCOG2202).

Aim: Gastric cancer is one of the leading causes of cancer-related mortalities worldwide. According to the pathological TNM classification, T3N0M0, Stage IIA gastric cancer has been excluded from the S-1 adjuvant chemotherapy trials. Thus, the clinical impact of S-1 adjuvant chemotherapy in patients with pathological T3N0M0 cancer and the associated prognostic factors have not been elucidated.

Outcome of donor lymphocyte infusion after allogeneic hematopoietic stem cell transplantation in relapsed myelodysplastic syndrome.

Background Aims: Allogeneic hematopoietic stem cell transplantation (HSCT) improves outcomes for myelodysplastic syndrome (MDS) patients, but relapse rates remain high, and postrelapse treatment options are limited. Therefore, this study aimed to identify the factors contributing to the response to donor lymphocyte infusion (DLI) in relapsed MDS patients post-HSCT.

Methods: This study included 107 patients with relapsed and DLI-treated MDS who underwent their first HSCT between 2002 and 2022 and were registered in the Transplant Registry Unified Program.

The Real-World Outcomes of Relapsed/Refractory Multiple Myeloma Treated with Elotuzumab, Pomalidomide, and Dexamethasone.

: A combination of elotuzumab, pomalidomide, and dexamethasone (EPd) was approved for the treatment of relapsed/refractory multiple myeloma (RRMM) following the ELOQUENT-3 phase II clinical trial. However, the clinical experience with this therapy is still limited. In this retrospective study, we analyzed the efficacy and safety of EPd in a real-world cohort of RRMM patients.

Influence of dementia-specialized care team on clinical outcomes in a general hospital.

Background: Because of the increasing prevalence of dementia in Japan, the government introduced financial incentives for specialized care for dementia at acute care hospitals in 2016. Our hospital then introduced a multidisciplinary collaborative specialized team, referred to as dementia-specialized care team. The aim of this study is to examine the influence of dementia-specialized care team on clinical outcomes for elderly inpatients.

Unprecedented Megakaryocytic Blast Phase Transformation in Chronic Myeloid Leukemia After 16 Years of Tyrosine Kinase Inhibitor Therapy.

We report the case of a 51-year-old Japanese man with chronic myeloid leukemia (CML) initially diagnosed in the chronic phase. For 16 years, the patient maintained chronic phase (CP) under treatment with first- and second-generation tyrosine kinase inhibitors (TKIs), including imatinib, dasatinib, and bosutinib, none of which resulted in ABL1 mutations. However, despite long-term disease stability, the patient experienced an abrupt progression to the megakaryocytic blast phase (MBP), a rare and aggressive form of CML.

Point-of-Care Lung Ultrasound to Evaluate Lung Isolation During One-Lung Ventilation in Children: A Blinded Observational Feasibility Study.

Background: Minimally invasive thoracic surgical techniques require effective lung isolation using one-lung ventilation (OLV). Verification of lung isolation may be confirmed by auscultation, visual confirmation using fiberoptic bronchoscopy (FOB), or more recently, point-of-care ultrasound (POCUS). The aim of this study was to prospectively compare lung ultrasound with clinical auscultation to confirm OLV before thoracic surgery in pediatric patients.

Overcoming post-transplant graft failure and adenovirus infection in a patient with -TKD-mutated mixed-phenotype acute leukemia: A case report.

Mixed-phenotype acute leukemia (MPAL) with -TKD mutations is a rare and challenging subtype of leukemia. Effective management strategies are crucial for improving patient outcomes. A 31-year-old man with -TKD-mutated MPAL achieved hematological remission through the JALSG ALL202-O protocol and gilteritinib, followed by cord blood transplantation (CBT).

Complete Response to Pembrolizumab in a Patient with Castration-Resistant Prostate Cancer with Both BRCA Positivity and a High Frequency of Microsatellite Instability: A Case Report.

Introduction: There have been few reports of patients for whom a cancer gene panel test for solid tumors revealed the simultaneous presence of BRCA mutation and microsatellite instability (MSI)-high status. BRCA mutations have been reported in 13% of castration-resistant prostate cancer (CRPC) patients, and 3.1% of prostate cancer cases are MSI-high/mismatch repair deficient.

Tumor thickness as a novel risk factor for lymph node metastasis by superficial squamous cell carcinoma of head and neck.

Narrow-band imaging combined with magnified endoscopy has enabled the detection of superficial squamous cell carcinoma of the head and neck (SSCCHN) that has been resected with minimally invasive treatment, preserving vocalization and swallowing functions. However, risk factors of lymph node metastasis (LNM) must be identified, as some patients with LNM have a poor prognosis. From an initial 599 patients with 700 lesions who underwent trans-oral surgery in 27 Japanese hospitals (a nationwide registration survey), we enrolled 541 patients with 633 SSCCHNs, as indicated by central pathological diagnoses.
